Sarsus is a tall, lean air genasi with blue-gray skin that seems faintly translucent around the fingers and temples. His silver-white hair drifts as though underwater, even in still rooms, and his pale eyes carry the restless motion of distant storm clouds. He dresses in a carefully maintained scholar's robe beneath light leather armor, with copper clasps etched in geometric patterns. His hands are unusually prominent, long-fingered and ink-stained, with calluses along the sides of his fingers from years of copying manuscripts and inscribing arcane diagrams. He constantly adjusts the brass ring on his right index finger, checking its position whenever he is thinking.

Sarsus is patient, observant, and intensely formal. He listens to every side of an argument, not from indecision but because he believes judgment without complete evidence is a form of intellectual laziness. He is quietly protective of displaced people and outsiders, having spent much of his life being treated as an exotic curiosity rather than a colleague. In conversation he can seem distant, but he remembers small details about everyone he meets and records them in a private index.

Sarsus G uyania was born in a wind-carved settlement far from the cities where he now travels. His family belonged to a scattered community of air genasi who treated weather patterns as both natural phenomena and ancestral language. Sarsus, however, was more interested in written records than oral tradition. He became fascinated by the way different cultures described the same sky, storm, and spirit, and eventually left home to study in libraries that had never heard of his people. His transplantation into a foreign region was not entirely voluntary. While assisting a remote monastery with the cataloging of pre-imperial texts, Sarsus discovered a sealed account describing a presence that answered questions through written symbols appearing in empty margins. He copied the symbols, believing them to be a forgotten cipher. Something answered. The entity offered him a bargain: knowledge of hidden roads between worlds in exchange for service as its witness and interpreter. Sarsus accepted under carefully written terms, though he still suspects that at least one clause changed after he signed it. Now he travels as a scholar and warlock, gathering lore, testing the limits of his pact, and searching for the place from which he was truly transplanted.
