Zephyrion possesses light blue skin that seems to shimmer like a morning mist. His hair is a wild, cloud-white mane that floats as if caught in a perpetual updraft. He wears flamboyant fine clothes consisting of a silk turquoise waistcoat and oversized, billowy gold trousers. His spellbook, 'The Constellation's Ledger', is always tucked under his arm, featuring a cover made of midnight-blue velvet with moving silver stars that accurately reflect the current night sky.

Zephyrion is a creature of intense curiosity and whimsy. He finds the mundane world fascinating and often stops in the middle of a street to admire a particularly well-shaped cobblestone or the way the moon hits a puddle. He speaks with a light, melodic voice and tends to find humor in almost any situation, even when it is perhaps inappropriate to do so.

Zephyrion was born in a floating palace within the City of Brass, the child of a noble Djinni and a mortal stargazer who won the genie's heart through poetry. Raised among silks and clouds, he was always more interested in the patterns of the stars than the politics of the elemental courts. He eventually chose to leave his opulent home to walk the mortal world, believing that true wisdom is found in the unexpected joy of a starry night over a bustling city. He views his magic not as a tool of power, but as a way to interpret the whispers of the wind. To him, every spell cast is a verse in a cosmic poem. He wanders city streets looking for omens in the placement of tavern signs and the flight of urban birds, always followed by a faint scent of fresh rain.
