Captain Himilco is one of the Anointed, an old warrior that's fought for the 10th for millennia. When the 1st Company was remade into a line company, Himilco relinquished his terminator suit to answer Castor's call for able commanders.

Himilco is a strong and able commander. He has a better grasp of tactics than most captains - and a sense of prudence that sometimes overrides his zeal. This has led to friction with the Chaplain of the 1st Company, who is not so old and tempered. Had this been any other Host it is likely that this would have been the end of Captain Himilco, but Castor the Apostle has decreed that it is his Will that Captain and Chaplain work together and that they will also be judged together.
