Ren is a three-foot-tall faerie with warm brown skin, short black curls, and large translucent wings veined with violet light. A smooth amethyst-like gemstone is set naturally into the center of his chest, glowing brighter when his patron's power stirs. He wears a carefully mended dark-blue coat, soft leather armor, fingerless gloves, and a collection of hidden pockets. His eyes are deep brown with faint purple rings around the irises.

Quiet, observant, and clever, Ren notices who is frightened before he notices who is dangerous. He is fiercely loyal and surprisingly dry-humored, especially when someone assumes his height makes him harmless. He prefers plans with three exits, but he will abandon any plan instantly if it means keeping Kera alive.

Ren was born among a hidden faerie enclave that survived by moving quietly between abandoned gardens, ruined shrines, and the edges of mortal settlements. He and Kera were inseparable from childhood, a partnership built from shared jokes, secret paths, and the practical certainty that neither would leave the other behind. When vampires descended on their refuge, Ren and Kera crawled into a collapsed root cellar and stayed motionless while the attackers searched above them. They survived because the creatures eventually lost interest, but Ren never forgot the helplessness of waiting in the dark while Kera trembled beside him. Afterward, Ren began forging travel papers and false names for other survivors, helping them disappear before the vampires could return. The work taught him deception, sleight of hand, and the value of being underestimated. It also brought him to a violet-lit shrine where an unseen patron offered power in exchange for future favors. Ren accepted before learning what the favors might become. His pact manifested as violet energy flowing through his wings and chest gemstone, giving him the means to fight, flee, and protect Kera. He knows the patron is cultivating something dangerous inside him, but whenever Kera is threatened, caution becomes a luxury he cannot afford. His goal is simple, even if achieving it is not, become strong enough that neither of them ever has to hide again.
