Katikai is a broad-shouldered half-orc with light green skin, a square jaw, and steady amber-brown eyes. A black lightning-shaped birthmark cuts diagonally from one side of his face to the opposite side of his jaw. He wears fully grey Moth Knight armor, reinforced with black and white stitching, and a bright pink orb is painted at the center of his chest. His helmet resembles a moth's face with slender antennae, but its open front leaves most of his face visible. From his back spread black and grey moth wings marked by large white spots, like moonlit eyes in a storm cloud.

Katikai is quiet, observant, and intensely earnest. He treats promises as physical things that must be carried carefully, and he prefers clear duties to vague affection. Although his expression often seems stern, he is fascinated by small signs of beauty, especially moths, unusual stones, and lights reflected in water. He is slow to trust, but once someone has earned his confidence, he watches over them with formidable loyalty.

Katikai grew up in Gravosh, where his strength was useful but his restlessness was not. He could carry more than most men, endure long workdays, and memorize the prayers recited by the town's shrine keeper, yet none of those things answered the question that had begun to trouble him. He felt as though his life had been built from sturdy stones without anyone explaining what the structure was meant to become. Rather than remain in Gravosh and inherit a predictable place in its guard or temple, he left for the wilderness in search of a purpose he could recognize when he found it. During a cold night beneath unfamiliar trees, Katikai dreamed of a bright pinkish light suspended in a field of darkness. It spoke without words, giving him a series of directions through mountains, ravines, and abandoned roads. He followed those instructions for weeks until he reached a distant temple built high on a mountain ridge. There, the Moth Knights recognized the mark on his face, or at least understood that the dream had brought him to them for a reason. Katikai joined their order as an acolyte and learned to turn his strength into disciplined motion, leaping from ledges and striking with a spear like falling starlight. He now searches for the source of the pink light, believing it may be a divine beacon, a warning, or the first sign of a darkness that only the Moth Knights can confront.
