Zyrillion possesses translucent skin that shifts between deep violet and cosmic blue, resembling the twilight sky. Their hair is a cloud of silver vapor that floats upward as if weightless. Their eyes are solid gold spheres with no pupils. They wear flowing, translucent silk robes that drift in an unseen wind, and they never quite seem to touch the ground. A massive diamond, swirling with tiny points of light like captured stars, hangs around their neck on a chain of meteoric iron.

Whimsical and perpetually distracted by the movements of planets that others cannot see. Zyrillion speaks in riddles and metaphors about the birth of suns. They find mortal concepts like money and borders hilariously small, often treating a king with the same playful irreverence they would show a street cat. They are deeply kind but fundamentally detached from the linear flow of time.

Zyrillion was once a minor noble of the Great Caliphate in the Elemental Plane of Air. During a meditative flight through a rift, they were pulled into the Astral Sea and drifted for what felt like a thousand years through the silent spaces between worlds. It was there that they encountered the Great Constellation, a sentient cluster of stars that granted them a portion of its cosmic essence in exchange for an eternal promise to see all the beauty the physical world has to offer. Zyrillion returned to the material realm changed. No longer just a genasi, they are a vessel for the starlight they once floated through. They view themselves as an observer of the grand dance of the cosmos, though they cannot help but intervene when the light of a world is threatened by darkness. They carry their home within the star-filled diamond focus, a fragment of the astral void they once called their own.
