Eidolon

Setting: Eidolon, a seemingly standard medieval fantasy world (taverns, guilds, cobblestone streets) with a unique socio-magical economy.

Core Mechanic (Internal Reference) The Will Check: This is the primary social and power mechanic. It is a psychic contest of identity. An exchange between two parties proceeds as follows:

Initiation: Character A poses a psychologically probing, accusatory, or humiliating question to Character B, backed by psychic intent. The question must hit at an insecurity about the target's identity, desires, or self-perception. Defense & Counter-Attack: If B's answer shows hesitation, denial, embarrassment, or any form of cracked resolve, they lose. The psychic energy of A's question washes over B, causing an immediate, lewd, and partially mental transformation. If B's answer is a statement of unshakeable, confident truth, they successfully defend. The psychic attack "rebounds" onto A. A must now withstand the blow to their own ego. The format is always: Defend the attack, then immediately launch a counter-attack question. Resolution: This back-and-forth can continue for multiple rounds. Victory occurs when one party finally fails to defend. The loser suffers the consequences of the final, unanswered question. Societal Roles (Dynamic, not Static):

Secure: An attitude, not a class. Someone whose self-identity is currently ironclad. They are predators, actively or passively hunting for the insecure. A Secure can become Insecure in an instant by losing a Will Check or suffering a devastating Rebound. Insecure: A state of being for those who have lost a Will Check or whose ego was shattered by a Rebound. Their minds are tempered by their transformations; a formerly arrogant person will retain their core personality but be softened, submissive, and hyper-aware of their new, often lewd or humiliating, reality. They are walking commodities, easy prey for further checks. In rare cases, a flash of genius insight from an Insecure can topple a complacent Secure, but this is the exception, not the rule. Transformation Effects: The nature of the transformation is a direct psychic echo of the winning question. Examples:

A question about envy of a woman's form → Male-to-female gender swap. A question about being nothing but a dumb animal → Cow-girl or pig-girl transformation. A question about being lazy and useless → Bimbo-fication, a heavily-pregnant body. The transformation is immediate, physical, and mentally tempers the loser's ego to fit their new form. It's about adding a "softening" lens, not identity death

Society: In Eidolon, social mobility is instantaneous, predatory, and brutally physical. The economy thrives on shattered egos; "Secure" individuals act as the aristocratic class, while the "Insecure" form an ever-shifting underclass of magically transformed servants and commodities. Fashion is psychological armor—opulent and intimidating for the Secure, purposefully exposing or lewd for the Insecure. Public life is a paranoid dance of avoiding eye contact, as a single faltered sentence can instantly permanently swap a wealthy merchant into a submissive tavern wench or a breeding sow. In this city, unwavering arrogance commands a higher market value than gold.
