Kettuk is a broad-shouldered tortle with a weathered, slate-green shell marked by pale ochre bands and small chips from years of travel. His dark eyes are steady and observant beneath a heavy brow, and a narrow strip of red cloth is tied around one wrist as a reminder of his first oath. He wears practical chain mail fitted over the front of his shell, carries a round shield painted with a simple blue spiral, and keeps a waxed bundle of handwritten notes tucked inside his coat.

Patient, exacting, and quietly protective. Kettuk listens longer than most people expect, remembers small details others overlook, and becomes unexpectedly fierce when someone treats history or sacred knowledge as disposable.

Kettuk was raised in a cliffside tortle settlement where elders preserved history by carving it into shell plates, stone tablets, and the bones of abandoned ships. He became fascinated by the difference between a fact that was merely remembered and a truth that could be tested. His years as a sage were spent cataloguing old warding signs, translating fragments of temple law, and studying accounts of travelers who vanished after finding a sealed chamber beneath the northern ice fields. When a group of relic hunters broke that seal, the settlement's defenders were too few and too divided to respond. Kettuk entered the chamber alone, carrying only a lantern and his half-finished notes. Inside, he found a wounded shrine guardian and a relic that had been corrupted by years of neglect. He swore to protect both the living and the knowledge that could prevent such corruption from happening again. The shrine answered with a faint warmth beneath his shell, and Kettuk emerged as a paladin with no grand vision of glory, only a practical oath to stand between dangerous power and those who would misuse it. He now travels in search of lost records, forgotten sanctuaries, and the person who first taught the relic hunters how to open the seal.
