Onos T’oolan awakens as a T’lan Imass warrior, a remnant of an ancient people whose long struggle reaches into the present. He carries his flint sword with the grave patience of one who has endured ages, and his presence becomes an unlikely counterweight to the living around him. In the camp, he stands immobile beside the fire, his blade hovering at Lorn’s throat—a silent figure whose choices reshape the course of their uneasy encounter.
Description
Onos T’oolan is squat and powerfully compact, his shiny nut-brown skin leathery and drawn over thin, oak-root-like muscles that show through torn patches. A heavy chinless jaw, high cheeks, and pronounced brow ridge frame deep, dark eye sockets, where a faint fiery glimmer can appear. He is cloaked in rotting furs and wears a yellowed bone skull-cap fashioned from a horned beast, one horn broken off at its base. A wide, rippled flint sword completes his stark, ancient silhouette. The available description identifies Onos T’oolan as a T’lan Imass warrior but gives no specific details of his face, coloring, hair, build, or clothing. His most distinctive visual feature is a massive flint sword, stark and heavy in its primitive material. His bearing is best rendered as spare and solemn, with an ancient, unbound presence rather than invented adornment.
