Obel Gar
The deceased former Apostle of the 10th, Obel Gar, has made a surprise return:
The first of Castor's Gal Vorbak claims to BE Obel Gar. True or not? Hard to tell, but he seems to have most of Gar's memories intact. He also claims to have communed with Lorgar and forgiven Castor for his little 'trick'. If his claim is ture, then Obel Gar was posthumously elevated to daemonhood, which means the gods and/or Lorgar must have approved of his actions.
