“They bear false versions of Legate Lanius' mask, the one Caesar fashioned for him. Thought it was an insult at first.... know better now. It's shaped from Divide metal, not with care and strength, but with hate. Keeps them anchored. Crude, effective - like the blades they carry, distant mirrors of their Legate. A symbol they can hold on to - while the Divide tears at them.”— Ulysses

His health and combat skills are higher than those of a normal marked man. As befitting his name, he fights using a flamer, raining blistering heat upon his enemies.
