The professional nature of the Old Dominion Army was best exemplified by its officer roster. A Xhiliarch, a commander of a thousand men, was both elected by his troops and trained by Dominion. Only those who had previously attained the rank of Centurion were eligible to become Xhiliarchs, who of their choosing traveled to Captias to receive training in grammar, arithmetic, and logistics, enabling them to become the professional officer corps that the legions needed to dominate the continent. Their high rank invariably meant they were buried with full honor and ceremonies, their embalming process and burial services much more thorough and complex than that of a simple legionnaire. As such, they retained their cognitive abilities when raised by the ungod as inanimate vessels, unlike the Legionnaires, who retain only a remnant of their former selves.
