Lamp is a slender, pale-gold-skinned aasimar with luminous silver eyes, soft white hair, and a gentle expression that rarely matches the unsettling visions surrounding him. He dresses in layered hermit's robes beneath a worn dark blue traveling cloak, with a lantern-shaped pendant hanging at his throat. When his celestial power stirs, faint golden light gathers around his shoulders like folded wings. He habitually adjusts the pendant whenever someone speaks about Moth, often leaning far too close to listen with complete, sincere interest.

Lamp is friendly, compassionate, and sincerely curious about everyone he meets. He treats Moth's disturbing whispers as reassuring companionship and often discusses them as casually as another person might mention the weather. He is patient with the frightened, fascinated by the unusual, and incapable of understanding why people react badly to descriptions of impossible anatomy. Lamp prefers kindness over suspicion, but once someone threatens a friend, his gentleness becomes quietly immovable.

Lamp was born beneath an unusually bright winter star, and his celestial heritage became apparent early through his silver eyes, natural warmth, and an instinctive ability to soothe minor wounds. He eventually withdrew from society, settling in a remote cave surrounded by silent pines. There he studied medicinal herbs, copied old religious texts, and pursued the unanswered questions that had followed him since childhood. Solitude suited him. People were loud, hurried, and often afraid of things they did not understand. One night, something answered his questions. Moth appeared first as a shape in the darkness behind his dreams, a vast presence with too many delicate wings and a voice like distant chimes heard underwater. Lamp did not panic. He asked whether Moth was lonely. The question fascinated the entity, and an unlikely friendship began. Moth showed Lamp impossible constellations, forgotten histories, and visions that would have shattered another mind. Lamp showed Moth jokes, campfire stories, and the simple pleasures of tea and conversation. When Lamp finally left his hermitage to explore the world, Moth came with him, granting him eldritch power and fiercely protecting him from forces that wished to study, bind, or destroy him. Lamp remains cheerfully unaware of how horrifying Moth appears to everyone else.
