Katik wears a charcoal-gray hood and a narrow, lacquered mask that conceals his dark elven features from the nose upward. He is lean rather than frail, with long limbs, deep brown skin, and tightly braided white hair threaded with bits of dull copper. His hands show the roughness of stone dust and old mining work. When standing still, he rests most of his weight on the balls of his feet, as if expecting the ground to shift beneath him. A faint violet glow sometimes pulses beneath the skin of his temples when his magic stirs.

Katik is watchful, dryly humorous, and intensely observant. He studies people before trusting them, but once someone has earned his confidence he becomes fiercely protective. He prefers precise explanations to comforting lies, and he treats every unusual thought or impulse as something that must be examined before it is obeyed.

Katik was born beneath the surface, in a drow mining enclave where faith and labor were treated as two sides of the same chain. His family carved routes through black crystal and pale stone, while the priesthood claimed the deepest chambers for sacred excavation. During one expedition, mind flayers descended upon the mine. Katik was captured, implanted with a tadpole, and left among other prisoners awaiting transformation. The invasion was interrupted before the process could be completed, and Katik escaped through a collapsed ventilation shaft, carrying the voices of the other victims in his mind. The tadpole did not die. It changed. It became a source of disturbing power, allowing Katik to hear thoughts, twist perception, and call up magic that feels less like spellcraft than a foreign intelligence speaking through his nerves. He spent years hiding among surface communities, eventually finding refuge in a small temple where he served as an acolyte. There he learned prayers, languages, and the discipline needed to keep his borrowed power from consuming his identity. He now travels beneath a hood and mask, seeking evidence of the mind flayers who took him and hunting for a way to silence the thing inside him without destroying the people he might still save.
