Kaaz is a tall, gaunt man in his late thirties with skin the color of aged parchment. His fingers are permanently stained with ink and his eyes are a piercing, unnatural shade of amber. He wears heavy black robes trimmed in crimson, and a faintly glowing dark crystal hangs from a chain around his neck.

Kaaz is cold, precise, and profoundly condescending. He speaks in long, complex sentences and views the world as a chaotic system that desperately needs to be categorized and controlled. He shows no emotion, seeing it as a defect of the lesser-educated mind.

Kaaz A'Dun spent twenty years as a senior cataloger at the Great Library, obsessed with the idea that the rise and fall of civilizations followed a predictable mathematical rhythm. During his research into forbidden pre-diluvian texts, he discovered a cipher that unlocked a communication channel with a powerful fiend. Seeing a logical path to infinite information, Kaaz readily agreed to the entity's terms, believing himself clever enough to navigate the contract's pitfalls. He now travels the realms not out of wanderlust, but to collect the missing variables for his grand theory of societal control. He views his warlock powers as mere tools of the trade, no different from a quill or a magnifying lens, provided by a business associate he intends to eventually outmaneuver.
