Crowvasia all have different personalities which means that the only thing the Crowvasia have in common is the fact that they have nothing in common. They are known to follow Hauberk, and this is thought to be because at least one of Hauberk's diverse personalities suit the Crowvasia. There are of course just as many that hate Hauberk for the same reasons. It is difficult for even high ranking demons to utilize Crowvasia on a large scale if they aren't Giltine. It is rumored that Giltine has in fact mobilized many of them recently.
