Each Aspect Shrine is led by an Exarch, an Eldar fallen to the curse of inability to leave the Path of the Warrior. These Exarchs are powerful warriors, doomed to either die on the battlefield, or to eventually be chosen to become the Avatar of Khaine. The first member or founder of an Aspect Shrine is called a Phoenix Lord. When an Aspect Warrior becomes an Exarch, they will don one of the ancient suits of Exarch armour that belong to that shrine, and this suit will bond to their flesh permanently. This means that the new warrior's soul merges with those of the previous wearers of the suit, which is essentially a compact and mobile version of the Craftworld's Infinity Circuit.
