Arleth Blightblade

His family used to be ancient nobility, his ancestor being a Lieutenant to Malekith himself, until the Druchii were forced from Ulthuan. The house and lands of his ancestors were given to those elves still in the Old World and are now in ruin because of scavenging by Humans for the stone and loot once the elves left. When he was taken by the witches from the street he was thrown into the cauldron but did not surface until the ritual was nearly done. He was thought dead until the final sacrifice rose from the cauldron. At this moment so did Arleth, and he dashed the other sacrifice's head against the side of the cauldron, killing him. He was the only one blessed by Khaine, other than the one he killed. He trained to be an assassin until it was found he had a penchant for magic and was then trained to be a Disciple of Khaine. His training progressed until an incident occurred that had him sent to Har Ganeth for training instead. 
    After his training was done, he was sent to be the second to one of the priests in the Watchtowers to the North. There he fought and honed his art, but regardless of how good he was he was never made Father of a temple among the watchtowers even though many of the Head priests died in battle, or by other means. Arleth had been stopped in his climb up the ranks of the Temple and had been sent out here so they would not have to deal with him. 
    When Arleth heard news of the invasion of Ulthuan he immediately joined the invasion force to prove himself in battle so that not even the Priests back in Har Ganeth could stop his rise. He had ulterior motives of course. The main being revenge for what had happened to his once noble family. As a result he has a deep hatred for the Empire and High Elves.
