Kantu Tzik is a broad-shouldered goliath with slate-gray skin weathered by salt, wind, and years of hauling line. Pale geometric birthmarks run from the left side of the neck down beneath the collarbone, resembling a rough mountain range. Their black hair is cut short except for a narrow braided strip tied with red sail thread. Kantu constantly checks the knot at their left wrist, tightening it whenever they feel anger rising. Their hands are thickly callused, their knuckles stained with tar, and their coat smells faintly of brine, pitch, and crushed juniper.

Kantu is blunt, watchful, and unexpectedly gentle with frightened people. They treat every room as if it were a ship's deck, noting exits, weak railings, loose objects, and who would be hardest to rescue. They laugh loudly after surviving danger, then grow quiet when praised for it.

Kantu Tzik was born in a highland settlement where the wind came down from the peaks hard enough to rattle roof stones. They left after discovering that the sea offered a different kind of mountain, one that moved, groaned, and swallowed the careless. A merchant crew took Kantu on as a deckhand, first for their strength, then for their uncanny ability to read weather in the pressure behind their ears. Years of hauling anchors, repairing storm-split spars, and sleeping beneath leaking canvas made them a sailor before they ever learned to call themselves one. During a blockade raid, Kantu discovered the terror hidden inside their own courage. When the boarding hook caught and an enemy officer struck down the ship's youngest deckhand, something ancient and enormous rose in Kantu's chest. They fought through the enemy line with a boarding axe, a length of chain, and bare hands, laughing until the deck ran clear. Since then, Kantu has feared calm more than fury. They joined a wandering adventuring crew after their captain began using that berserk rage as a weapon against allies and enemies alike. Kantu now raids only those who prey on the helpless, but every battle tests whether they are still choosing the target, or merely looking for an excuse to become the storm.
