Elemental Realms AU: Character & Lore Wiki

---

Overview & World Lore

The Elemental Realms AU is set in a divided land split among four powerful elemental kingdoms. Each nation is bound to a specific elemental magic system, which manifests universally in its citizens on their 18th birthday in a collective ceremonial awakening. Despite sharing a continent, deep historical grievances and political tensions have led the elder rulers to harbor intense hatred toward rival realms.

Unbeknownst to the kings and queens, the younger generation of princes and princesses secretly question this inherited enmity, finding no logical reason for the perpetual conflict.

The Four Kingdoms

1. The Verdant Realm (Plant Kingdom)

• Elemental Magic: Flora manipulation, plant growth, wooden barriers, toxic spores, and vine entanglement.
• Capital/Rulers: Governed from the Canopy Citadel by King Bramble (Gaster) alongside his sons, Prince Thorn (Sans) and Prince Vine (Papyrus).

• Capital/Rulers: Governed by King Flame (Asgore) and Queen Flare (Toriel), alongside Prince Ember (Asriel).
• Culture: Defined by forge-cities, volcanic energy, and strict tradition. The kingdom's leadership maintains a harsh stance against external realms, fearing foreign invasion will quell their sacred hearths.

3. Zephyria (Air Kingdom)

• Capital/Rulers: Governed from the Cloudspire by its royal lineage, with Princess Breeze (Alphys) serving as high royal heir and chief strategist.

Main Character Profile: Thorn (Sans)

• Name: Thorn
• Original Counterpart: Sans the Skeleton
• Role/Status: Prince of the Verdant Realm (Plant Kingdom)
• Species: Skeleton Monster / Plant Elemental

Appearance & Clothing

Thorn’s head and facial structure perfectly blend classic skeleton traits with the botanical magic of King Bramble's realm.

His smooth, bone-white cranium serves as a sharp backdrop for the lush, vibrant plant growth sprouting directly from his head. Framing the left side of his skull is a thick, sweeping tuft of rich, leafy green foliage that behaves much like a side-swept fringe. The individual leaves layer closely over one another, cascading down toward his cheek with a soft, natural curve. Small, bright lime-green petals or glowing spore droplets float lazily around his head, hinting at the active, innate magic pulsed through the royal plant lineage.

On the right side of his head sits a distinct, dark gray-to-black ear covering or structural accent, balancing out the asymmetry of his overgrown leaf-fringe. His facial expression carries the easygoing, slightly enigmatic smirk typical of a Sans variant, though soft pale-teal markings rest lightly beneath his eye sockets like delicate magical blush or lichen growth.

His visible right eye socket features a dark interior with a strikingly bright, glowing white ring pupil, giving him an intense yet calm gaze. The contrasting left eye remains shadowed behind the lush green foliage, adding a layer of mystery to the young prince who questions the deep-seated hatred between the four element-bound kingdoms.

Thorn’s attire strikes a distinct balance between royal prestige and the natural, overgrown magic of the plant kingdom. Every layer of his outfit emphasizes his identity as Prince of the plant domain under King Bramble. he is 6 feet and 2 inches tall

• Upper Body Attire: He wears a royal dark green jacket with a subtle gradient transitioning into deeper emerald towards the bottom hem. The shoulders are styled with regal fringe epaulets, adding structure to his royal silhouette. Beneath the open jacket, he wears a light mint-green vest lined with a center band of crisp white trim and distinct gold buttons down the front.

• Sleeves & Arm Accessories: His long sleeves end in structured dark green cuffs fastened with gold button details. Fitting closely under his left sleeve is a dark, crisscross fishnet or lattice sleeve guard that extends down past his wrist, giving his left arm a protected, functional edge. His hands show detailed green botanical markings that resemble moss or spotted foliage patterns.

• Lower Body Attire: Thorn wears dark charcoal-grey shorts that rest above the knee. The shorts feature prominent dark grey belt loops or straps with metallic buckles along the bottom hem.

• Footwear & Botanical Accents: His footwear consists of sturdy, dark green platform boots. Wrapping intricately around his calves and the base of the boots are wild, leafy vines that twist upward, symbolizing his connection to plant magic. Spotted moss-like patterns decorate his left lower leg, matching the design on his hands.

• Headpiece & Foliage Accent: Atop his head rests a lush, sweeping crown of vibrant green leaves and foliage that drapes over the left side of his skull like long, swooping bangs, completing his botanical prince aesthetic.

Personality & Traits

Thorn’s Personality

On the surface, Thorn carries the signature relaxed, easygoing charm classic to Sans, but his royal status and the realm's deep-seated rivalries give him a unique, multi-layered temperament. Despite being raised by King Bramble in a realm that thrives on historical grudges, Thorn possesses an innately open-minded and insightful view of the world. He finds the ancestral hatred between the four elemental kingdoms completely senseless, often viewing the old feuds as an unnecessary burden. This puts him at odds with the strict, traditional expectations of the Skeleton Kingdom's court, where he is expected to view Breeze, Drip, Ember, and their lands as bitter enemies.

Instead of showing hostility, Thorn approaches the world with quiet curiosity and a gentle, observant nature. He is intensely loyal and protective toward his brother, Vine, often acting as a grounding presence whenever royal politics or family expectations get too overwhelming. Beneath his casual exterior lies a sharp, strategic mind; he uses a laid-back facade to avoid unnecessary conflict with his father, King Bramble, while secretly hoping for a future where the elemental kingdoms can coexist.

Thorn is naturally empathetic, deeply attuned to the life and growth around him, which aligns perfectly with his plant affinity. He enjoys low-stakes humor, bad plant puns, and peaceful moments spent away from the castle walls. However, if his loved ones or the fragile peace between the royal heirs are threatened, Thorn’s gentle demeanor yields to a firm, unyielding resolve—much like roots breaking through solid stone. His biggest driving motivation is his desire to understand the other heirs, secretly wishing to bridge the divide between Zephyria, Tidecrest, the Dreemurr Kingdom, and his home.

• Magical Awakening: Like all citizens, Thorn received his full botanical magic upon turning 18.
• Perspective on War: He finds the elder generation's hatred toward the other kingdoms pointless and seeks casual opportunities to interact with royalty from rival lands.

[Ecto-Body Mechanics: Thorn can manifest an "ecto-body," a semi-solid, glowing physical form made entirely of condensed magical ectoplasm over his skeleton. This ecto-body matches his signature magic color (typically glowing dark Green for Thorn). It behaves like soft skin or flesh, allowing him to experience human-like touch, taste, and physical intimacy. He can summon or dismiss it at will, either partially (e.g., just an ecto-tongue to taste food/kiss) or fully to cover his entire skeletal frame. (ecto cock is a foot long and 5 inch thick)]
