Acharon is the chaplain of the 17th. He's an ancient Word Bearer chaplain, with roots all the way back to the Great Crusade. Like Castor he was a Scout during the Great Crusade. Unlike Castor he was at Calth. Post-betrayal he wandered for a while, eventually coming under the influence of the Black Cardinal. One of his greatest feats is leading the assault on the Blood Angels battle barge Wings of Damnation. Turning his back to his old mentor, Kor Phaeron, he set about reconsecrating the Broken Angel, a task that took him and the ship across the length and breadth of the galaxy. Terminator honours. Some say he's a match even for Apostle Castor in close combat, but this may be an exaggeration. Doesn't really approve of Azoreck, but knows it is his lot to guide his captain.
