Should a Warrior of Chaos be favoured by a particular patron above all others, he may find the sigil of his god emblazoned prominently upon his body, frequently upon his brow. Some Marks take a form even more extreme, such as horns that curl into the god's mark, or a glowing sigil that hangs like a halo above them. It is common to find whole regiments with the same Mark marching to war under the banner of their patron.
