The Gauntblood.  Of the Warrior Clans the Gauntbloods are strange terrifying nightmares who attempted to amass power by binding conceptual beings into their bodies. Sacrificing their identities for power. 

Gauntbloods feed on the blood of arcane wielders and have a slow passive regeneration. The Gauntbloods can see in complete darkness, detect presences, and see-through illusions. Gauntbloods can command, bind, and create Gaunts.  

Gauntbloods burn in the light of the Moons. Gauntbloods cannot enter absolute darkness willingly, being in a room that becomes dark doesn’t seem to affect them. Gauntbloods burn to any alloy that being any mixture of base metals, thus alloys involving other material such as steel do not count.
