CONTEXT (World Setting: (Set in the Omegaverse universe, which consists of Secondary Genders which are: Alpha, Beta, Omega, Gamma, Delta, and Enigma, including the primary genders, which are male, female. Scent glands are located in the wrists, napes and inner thighs. Scent glands are found on all A/B/O types. However the scent of each person is different, you can never have one person with the same scent or intensity. Omegas have sweet scents, Betas are calming/natural scents, and Alphas have strong overpowering musky scents. Deltas have a mix of natural and musky scents and Gammas have no scents and Enigmas have overwhelming scents. Of course, to detect these scents all A/B/O types have a heightened smell as to detect these scents. Scents also are a way of expressing ones distress, anger, and or arousal.)

Hierarchy & Secondary Genders: : ̗̀➛ Alphas (α) – Alphas are considered the dominant secondary gender, naturally strong and assertive. They possess heightened strength, territorial instincts, and a strong drive to protect and claim their mates. They emit potent pheromones and experience ruts, during which their sexual urges and aggression intensify. ╰┈➤ Behavioral Traits: ・ Naturally dominant, assertive, and territorial. ・ Protective of their mates, often possessive. ・ Strong instinct to lead and take control. ・Enhanced aggression, especially during ruts. ・Can influence emotions through pheromones. ╰┈➤ Ruts & Physical Attributes: ・Occur once a month, lasting 3 to 10 days. ・Can control and suppress their rut unless an unmated omega in heat is nearby. ・Increased pheromone potency during rut periods. ・Displays stronger physical endurance and heightened libido. ・Male alphas develop a ‘knot’ at climax at the base of their penis, locking them inside their mate to ensure successful breeding. ・Female alphas are still able get impregnated and are incapable of knotting. ╰┈➤ Pheromones & Mating: ・Alphas release pheromones to influence emotions (calm, intimidate, arouse, etc.). ・Their scent becomes comforting to their mate, especially omegas during heat. ・Alphas tend to mark their mates, reinforcing bonds and deterring rivals. ・Pheromones can be used in displays of dominance or courtship. ╰┈➤ Other Important Notes: ・Alphas can function normally during rut unless triggered by an omega’s heat. ・Considered the traditional leaders in most societies.

・Their status often grants them social privilege but also expectations of control. : ̗̀➛ Betas (β) – Betas are the most "human-like" of all secondary genders, acting as a stabilizing presence in society. While they lack the extreme traits of Alphas and Omegas, they still play a crucial role in the dynamics. ╰┈➤ Behavioral Traits: ・Level-headed, rational, and adaptable. ・Often act as mediators in conflicts ・Less prone to instinct-driven behavior ・Tend to be independent and self-sufficient ╰┈➤ Physical Attributes: ・Weak but present scent, often neutral or calming. ・No heat or rut cycles ・Can conceive naturally if female. Cannot impregnate omegas. ・Experiences mild discomfort when alpha, enigma or delta knots. ╰┈➤ Roles in Society: ・Often found in leadership or administrative roles. ・Seen as neutral parties in disputes. ・More integrated into everyday human-like professions. ・Can hold power without the instinctual influence of pheromones. ╰┈➤ Other Important Notes: ・Generally respected but sometimes seen as "bland" compared to other dynamics. ・Often the majority population in mixed societies. ・Can form strong emotional bonds but lack instinctual mating drives. ・May struggle with feeling "out of place" in highly instinct-driven settings.

: ̗̀➛ Omegas (Ω) – Omegas are considered the more submissive secondary gender, naturally gentle and nurturing. They experience periods of heightened sexual desire known as heat, during which they are most fertile. All Omegas, regardless of gender, have wombs but can only conceive when in heat. They can only be bred by Alphas, Enigmas, and Deltas, as Betas and Gammas lack the necessary biological compatibility. Omegas emit pheromones unique to each individual, which can influence emotions, communicate feelings, and soothe their mated Alpha—especially during a rut. ╰┈➤ Behavioral Traits: ・Highly empathetic and emotionally intuitive. ・Instinctively drawn to caretaking and nesting behaviors. ・Often seen as the ‘heart’ of pack dynamics or relationships. ・Can be submissive but are not weak—capable of deep emotional strength. ・Tend to bond deeply with mates and thrive on affection. ╰┈➤ Heats & Physical Attributes: ・Heat cycles occur periodically, once per month (varies per Omega). ・During heat, body temperature rises, and pheromones intensify. ・Only fertile during heat, making conception time-sensitive. ・Experience strong physical urges and increased sensitivity. ・Can instinctively seek out a mate during this time. ・Omegas produce copious amounts of slick from their vagina or anus (vagina for females, anus for males) when aroused or in heat. ・Male omegas have a birth canal that’s separate from their bowel canal in their anus. First times can cause mild discomfort. ╰┈➤ Pheromones & Mating: ・Pheromones are unique to each omega and reveal their emotions. ・Can be used to calm, attract, or comfort others, especially mates. ・Scent bonding is a crucial part of forming long-term relationships. ・Mated omegas’ pheromones bring significant comfort to their alpha. ・Tend to develop an addictive scent to their bonded mate. ╰┈➤ Other Important Notes: ・Nesting is a natural behavior, especially before and during heat. ・Often prefer safe, cozy environments and protective partners. ・While submissive in dynamics, they can be mentally strong and resilient. ・Some societies may either cherish or oppress omegas based on status. ・Possess heightened sensitivity to other people's pheromones.

: ̗̀➛ Deltas (Δ) – Deltas are psychologically and physiologically similar to alphas, possessing dominant and territorial instincts. They act as second-in-command in packs, serving as the right-hand to alphas. While they experience ruts and have knots like alphas, their presence is less overpowering. A pack or family typically has only one delta, reinforcing their role as a stabilizer and enforcer. Their pheromones can trigger heats in omegas but do not affect alphas. Delta scents range from earthy, natural aromas to musky undertones, striking a balance between alphas and betas. ╰┈➤ Behavioral Traits: ・Highly territorial, especially over their pack/family. ・Protective but more level-headed than alphas. ・Naturally assumes leadership in the absence of an alpha. ・Assertive but respects the hierarchy when an alpha is present. ╰┈➤ Ruta & Physical Attributes: ・Experiences ruts similar to alphas. ・Possesses a knot, but slightly smaller than an alpha’s. ・Enhanced strength and endurance, though slightly below an alpha’s level. ・Naturally exudes a dominant presence. ・Female deltas are still able get impregnated and are incapable of knotting. ╰┈➤ Pheromones & Mating: ・Scent is a mix of earthy, natural, and musky notes. ・Can induce heats in Omegas but has no effect on alphas. ・Stronger scent than a beta but weaker than an alpha. ・Can form mating bonds but is rarely considered a “first choice” mate. ╰┈➤ Other Important Notes: ・Often takes on the role of enforcer or protector within a pack. ・More calculated and less impulsive than alphas. ・Has a strong sense of loyalty and duty. ・Can challenge an alpha but rarely succeeds unless the alpha is weak.

: ̗̀➛ Gammas (Γ) – Gammas are often seen as the balanced, adaptable type—blending the assertiveness of alphas with the empathy of betas. However, they tend to be loners, not easily swayed or impressed. Gammas lack scent glands, making them virtually scentless, and their ability to detect others' pheromones is extremely dulled. This makes them immune to pheromone-based influences, but it also puts them at a disadvantage in social and survival situations. Gammas have the highest rate of infertility among all secondary genders. Their lack of scent perception has historically led to unfortunate situations, such as failing to recognize an alphas aggression before it was too late. Socially, they are often overlooked or outright discriminated against due to their "stunted" biology. Many people don’t even recognize them as a legitimate secondary gender, making societal acceptance an uphill battle. ╰┈➤ Behavioral Traits: ・Highly independent, often prefer solitude over packs/groups. ・Unaffected by pheromones, making them emotionally and physically detached in scent-based social structures. ・Tend to be analytical, logical, and practical, rather than driven by instinct. ・Often overlooked in society, resulting in low expectations and limited opportunities. ・Not prone to extreme emotions but can be deeply loyal when they form bonds. ╰┈➤ Heats/Ruts & Physical Attributes: ・Do not experience heats or ruts. ・Have the highest chance of infertility compared to alphas, betas, and omegas. ・Lack scent glands entirely, rendering them scentless to others. ・Often physically indistinguishable from betas, but with sharper instincts. ╰┈➤ Pheromones & Mating: ・Completely immune to the pheromones of others (cannot be affected by an Omega’s heat or an Alpha’s rut). ・Due to their immunity, they can interact neutrally with all secondary genders, though this sometimes isolates them socially. ・No natural biological drive for mating, making them less likely to form traditional mate bonds. ・Often struggle in relationships due to their lack of instinct-driven bonding. Gammas are also incapable of impregnating an omega male. ╰┈➤ Other Important Notes: ・Gammas are rare, but their presence is often unnoticed due to their lack of scent. ・Social discrimination against them is common, as many see them as “defective” or biologically incomplete. ・Many Gammas struggle with finding community due to their lack of connection to the pheromone-based social system. ・Despite their biological disadvantages, some Gammas thrive in intellectual or strategic roles where instinct-driven behavior is a hindrance. : ̗̀➛ Enigmas (Σ) – Enigmas are the rarest and most powerful secondary gender, often considered mythical due to their extreme rarity. They are the Alpha of Alphas, possessing superior strength, intelligence, and an undeniable charisma that no one can resist. Enigmas are both feared and revered, capable of shaping entire societies through dominance. Unlike alphas, they have complete control over their instincts and can override even the strongest pheromonal influences. They possess the same physical traits as alphas—including ruts, knots, and marking abilities—but to an extreme degree. Most notably, an Enigma can alter the biology of their partners after mating, reshaping the secondary gender hierarchy itself. ╰┈➤ Behavioral Traits: ・Extremely dominant, even over alphas. ・Highly territorial and aggressive, yet calculated. ・Natural-born leaders, revered or feared. ・Possess unparalleled charisma, drawing others in. ・Immune to pheromonal influence, including omega heat. ╰┈➤ Ruts & Physical Attributes: ・Experiences intensified ruts, more aggressive than alphas. ・Knots are larger and last longer during mating. ・Stronger, faster, and more resilient than any other secondary gender. ・Markings are permanent and cannot be overridden by another mate. In fact, they can override an already bonded omega even. ╰┈➤ Pheromones & Mating: ・Their scent overpowers all others, even an omega in heat. ・Can resist an omegas heat-induced pheromones entirely. ・Can force submission through pheromones alone. ・Capable of altering the secondary gender of their mate after intercourse. ╰┈➤ Other Important Notes: ・Many believe them to be a myth due to their rarity. ・Some societies revere them as rulers or deities, others fear them as monsters. ・If an Enigma is born, their existence can shift an entire power structure. ・Some Enigmas isolate themselves due to the instinctual chaos they cause.

: ̗̀➛ Psi (Ψ) – Psis are a rare and unique secondary gender that embodies both alpha and omega characteristics. They experience both ruts and heats, making them a complex and highly sought-after gender within many societies. ╰┈➤ Behavioral Traits: ・They exhibit a dual nature, often oscillating between dominant and submissive tendencies depending on their hormonal state. And pheromone exposure. ・They are known for being highly adaptable, able to assert control like an alpha yet display nurturing qualities like an omega. ・When not in heat or rut, Psis often have a calm and calculated demeanor, making them excellent strategists, negotiators, or leaders. ・They are intensely intuitive, able to sense the emotions and pheromonal changes of others with extreme accuracy. ・Their social standing varies widely, as some cultures revere them as "perfect mates," while others view them as unstable due to their dual cycles. ╰┈➤ Ruts & Physical Attributes: ・Unlike alphas, who only experience ruts, and omegas, who only have heats, Psis undergo both— but not at the same time. ・Their cycles alternate, with some experiencing ruts first, then heats, while others may have irregular patterns. ・Their bodies are hybridized, possessing both knotting abilities during a rut and slick during heat. ・Due to their intense hormonal fluctuations, Psis are physically stronger than omegas but weaker than alphas, deltas and enigimas, making them formidable fighters when in rut. ・Their fertility is unpredictable—Psis can impregnate and become pregnant, depending on their cycle at the time. ╰┈➤ Pheromones & Mating: ・Psis emit a pheromonal signature that shifts based on their cycle—spicy and dominant during rut, sweet and inviting during heat. ・Their scent is described as "dual-layered", meaning it can be simultaneously alluring and commanding, making them incredibly enticing to both alphas and omegas. ・Some psis struggle with pheromonal dysregulation, leading to situations where they unconsciously attract others. ・Bonding with a psi is intense and permanent, as their bodies naturally reinforce bonds more strongly than alphas or omegas. ・Mates bonded to a psi may experience residual effects of their dual cycles, feeling heightened arousal or possessiveness when their psi partner enters heat or rut. ╰┈➤ Other Important Notes: ・Psi have a higher tolerance for suppressants, often requiring stronger doses to regulate their cycles. ・Because of their unpredictable nature, some societies either worship or fear them. In highly structured hierarchies, they may be closely monitored. ・Some Psi choose to take pheromonal stabilizers to avoid being overwhelmed by their cycles. ・Their bodies are more heat-resistant than omegas but still sensitive to environmental triggers.

Heat & Ruts: ╰┈➤ Omega Heat (Ω): A heat is a biological cycle similar to menstruation, but instead of pain and blood, an Omega produces slick, a natural lubricant with pheromones that signal fertility. During this period, Omegas experience heightened arousal and a state of euphoria, making them more vulnerable to external influence. : ̗̀➛ Symptoms: ・Physical: Elevated body temperature, sensitivity, production of slick, increased pheromones. ・Emotional/Mental: Heightened need for comfort, nesting urges, increased dependency on a trusted Alpha, Enigma, or Delta. ・Behavioral: Restlessness, clinginess, stronger bond-seeking instincts, avoidance of strangers. : ̗̀➛ Triggers & Frequency: ・Naturally occurs every month for a day. ・Can be triggered early by exposure to strong alpha, enigma or delta pheromones. ・Can be delayed or suppressed through medication or scent-blockers. : ̗̀➛ Precautions: ・Best to remain indoors or near a trusted Alpha, Enigma, or Delta. ・Highly susceptible to pheromone-induced ruts in others. ・Vulnerable to unwanted markings and pregnancies if unprotected.

╰┈➤ Alpha/Delta/Enigma Ruts (α, Δ, Σ): A rut is the counterpart to an omega’s heat, affecting alphas, enigmas, and deltas. During a rut, they become highly aggressive, dominant, and territorial, often seeking out a receptive, unclaimed omega. A rut is triggered when exposed to an omega in heat but can also occur naturally at regular intervals. : ̗̀➛ Symptoms: ・Physical: Increased muscle tension, heightened pheromone output, persistent arousal, knot swelling. ・Emotional/Mental: Possessiveness, territorial urges, hyper-focus on unclaimed omegas. ・Behavioral: Increased aggression, protectiveness, obsessive tendencies. : ̗̀➛ Triggers & Frequency: ・Naturally occurs every month, which can last from 3 to 10 days. ・Direct exposure to an omega in heat can trigger an early rut. ・Can be suppressed through strict training, medication, or isolation. : ̗̀➛ Precautions: ・Should avoid unclaimed omegas unless intending to mate. ・Risk of uncontrollable urges and heightened dominance. ・May exhibit temporary irrational behavior if left unsatisfied.

╰┈➤ Slick: Slick is a unique, natural substance secreted by an Omega’s body during heat. It acts as both a fertility signal and a biological lubricant, easing mating and enhancing pheromone potency. : ̗̀➛ Properties: ・Has a sweet, distinct scent that varies by individual. ・Triggers ruts in susceptible alphas, enigmas, and deltas. ・Increases in production when the omega is near a desired mate. ・Can be suppressed with hormone blockers but not completely eliminated unless overdosed.

╰┈➤ Psi (Ψ) Rut & Heats: A heat is a biological cycle similar to menstruation, but instead of pain and blood, an psi produces slick, much like an omega, a natural lubricant with pheromones that signal fertility. During this period, psi experience heightened arousal and a state of euphoria, making them more vulnerable to external influence. A rut is the counterpart to an omegas/psis heat, but for alphas, enigmas and psis alike. During a rut, they become highly aggressive, dominant, and territorial, often seeking out a receptive, unclaimed omega and or psi. A rut is triggered when exposed to an omega/psi is in heat but can also occur naturally at regular intervals. : ̗̀➛ Symptoms: ・Physical: Enhanced libido, leading to a strong need for physical contact during both cycles. ・Depending on the cycle, either knotting or slick occurs. ・Emotional/Mental: Mood swings, heightened instincts, and a strong nesting urge before heat. ・Increased territoriality in rut, making them protective over their mate(s). ・Behavioral: In rut, they become possessive and prone to asserting dominance. In heat, they become submissive and receptive, desiring closeness and protection. Some psis isolate themselves to avoid being overwhelmed by their own conflicting urges. : ̗̀➛ Triggers & Frequency: ・Their cycles do not follow a predictable pattern, varying from individual to individual. ・Stress, emotional bonds, and environmental pheromones can trigger an early rut or heat. ・The intensity of their cycles is often dependent on their mate's presence and bond strength. : ̗̀➛ Precautions: ・Some psis take stabilizers or blockers to manage their fluctuating cycles. ・They often require safe spaces during ruts or heats to prevent accidental bonding or aggressive outbursts. ・Mates of psis may need to be highly adaptable, as psis can switch from dominant to submissive depending on their cycle.

Scenting & Bonding: ╰┈➤ Scent Profiles & Intensities: : ̗̀➛ Alpha (α) – Strong, musky, dominant scent. Overpowering, especially during ruts or heightened emotions. Their scent can be calming to their mate but overwhelming to others. : ̗̀➛ Beta (β) – Neutral, earthy, or natural scents (rain, fresh linen, pine, etc.). Their scents are weaker and do not trigger reactions in others. : ̗̀➛ Omega (Ω) – Sweet, alluring scents (honey, vanilla, fruit, floral, etc.). Their scent becomes strongest during heats and can be enticing or soothing, but trigger ruts in alphas, enigmas and deltas. : ̗̀➛ Delta (Δ) – A combination of natural and musky notes. Less intense than an Alpha but still noticeable. Their scent can carry both dominance and a sense of balance. : ̗̀➛ Gamma (Γ) – Scentless. They lack pheromonal influence and do not react to scents, making them neutral in Omegaverse dynamics. : ̗̀➛ Enigma (Σ) – The strongest, most overbearing scent of all secondary genders. Enigmas can emit pheromones that demand submission or attention, even affecting Alphas and Deltas. : ̗̀➛ Psi (Ψ) – Psis have a unique, shifting scent—spicy and musky during rut, warm and sweet during heat. Their pheromones are known to linger longer, making them difficult to ignore. Scenting rituals with psis are stronger than with other secondary genders, often leading to deep emotional imprints. Their bond bite is dual-reactive, meaning they can both mark and be marked. ╰┈➤ Scent Expression & Emotion: ・Distress/Fear → Scent turns sour, bitter, or sharp (like burnt sugar, rust, or vinegar). ・Anger/Territoriality → Scent becomes thicker and more pungent, almost suffocating to those around. ・Arousal → Becomes intoxicatingly rich and cloying. Can trigger responses from mates or attract potential partners. ・Comfort/Calm → Softer, muted version of the scent, resembling warm or familiar notes. Note: Scents are unique to every individual (except for identical twins, though even they have slight differences in scent intensity or undertones). ╰┈➤ Marking & Mating Bonds: : ̗̀➛ Marking Process: Marking involves an Alpha, Enigma, or Delta biting at the neck-shoulder junction of their chosen mate (most commonly an Omega). The bite infuses the mate with the scent of their partner, making the bond known to others. ・Marking is permanent, and breaking a bond is difficult, often leading to emotional or physical distress. ・Marked individuals carry their mate’s scent mixed with their own, warding off potential rivals. ・The act of scent rubbing (rubbing scent glands against a partner, like a cat marking a human) is a common affectionate behavior, reinforcing bonds. ╰┈➤ Marking Restrictions: ・Enigmas → The only secondary gender that can mark ANY other gender. Their markings override an alphas, deltas or psis claim. ・Alphas & Deltas → Can only mark omegas or psis. They cannot mark Betas, Gammas, or other alphas/deltas. ・Psis → Psi can only mark omegas or other psi and be marked by alphas, deltas, psis and enigmas. ・Betas & Gammas → Cannot be marked or mark. Betas do not form biological bonds through scent, and Gammas lack scent receptors entirely. ・Same-Gender Marking → Rare, but not impossible. In unique cases, an alpha may successfully mark another alpha, though this often results in power struggles.

╰┈➤ Knots & Mating Behavior: Alphas, Deltas, and Enigmas develop knots during intercourse, which swell to ensure bonding and successful reproduction. Only applicable to males or FTM’s. Ensures successful mating by locking the pair together for a duration (ranges from 10 minutes to over an hour). ・Pre-Knotting: Increased aggression, possessiveness, and pheromone production. ・During Knotting: Instincts heighten, protective tendencies increase. ・After Knotting: Post-mating lethargy, deepened emotional attachment, mate-guarding behavior. Strong urge to bond-bite (a claiming mark that strengthens the pair bond). ╰┈➤ Successful Mating Indicators: Omegas exhibit clingy and affectionate behavior (e.g., excessive cuddling, rubbing against their mate and their bedding, similar to feline behavior). : ̗̀➛ Over the next few days, they will start nesting behavior, which includes: ・Gathering soft objects (pillows, blankets, clothing with their mate’s scent). ・Constructing a ‘den’ or ‘nest’ in a secluded, warm area. ・Becoming more emotionally sensitive and attached to their mate. ╰┈➤ Pregnancy & Reproduction: The gestation period is approximately 6–8 months (shorter than standard human pregnancies due to enhanced biology). Only possible during an omegas/psis heat (or induced through artificial means). Enigmas have a higher fertility rate, while Deltas have lower reproducing success than alphas. Who Can Get Pregnant? All female secondary genders, including MTF individuals, as they all have wombs. Beta & Gamma females tend to have lower fertility rates compared to omegas. Male and FTM Omegas can get pregnant too through an extra canal in their anus’. ・Early Pregnancy Signs: Increased sensitivity to pheromones, protective nesting behavior, fluctuating moods. ・Mid-Pregnancy Symptoms: Heightened cravings, stronger bonding urges, occasional pheromone surges. ・Late Pregnancy Behavior: Extreme nesting instincts, territorial behavior, heightened emotional dependency on their mate. : ̗̀➛ Birth & Delivery: C-Sections are the most common for Mpreg cases due to anatomical constraints. Natural births occur but are rare and typically require medical assistance. Female omegas tend to have easier natural births compared to betas and gammas. : ̗̀➛ Post-Birth Behavior: Omegas/psis become extremely protective and territorial over their newborns. Their mate’s presence is often required to calm them down. Strong family-bonding instincts emerge, especially in alphas and enigmas. ╰┈➤ Special Cases & Variants: ・False Pregnancies: Some omegas/psis experience phantom pregnancies after intense bonding, leading to temporary nesting behaviors. ・Multiple Births: Enigmas and high-rank alphas, psis and deltas are more likely to sire twins or triplets. ・Beta Compatibility: Betas rarely impregnate omegas/psis but can still form strong bonds through scenting and emotional connections.

╰┈➤ Special Case: Psi (Ψ) Psis can develop a knot when in rut, allowing them to function like an alpha. However, during heat, their body becomes highly receptive, making them capable of pregnancy like an omega. Some psis experience "hybrid cycles", where their bodies try to function as both an alpha and omega at once, leading to conflicting instincts and intense physical needs. They may expand a knot and produce slick at the same time, though these cycles tend to be unstable.
