A pair of Demon Cockroaches implied at one point that the grand plot of the comics involves at least nine distinct factions, at least some of which were not yet known about at that point. Eventually, at the commentary in Book 4, "Don't Split the Party", author Rich Burley confirmed that the Cockroaches' claim was accurate and furthermore that one of those factions would be introduced in Book 5 (which turned out to be "Blood Runs in the Family"), implying that said faction is either the Vector Legion, Hel or perhaps the Draketooth Family. Forum discussion on the matter is recurrent.
