From Unofficial Ansalon Wiki
The Dragonarmies are the Armies of Takhisis, intent to claim all of Krynn as her domain. There are five sects, one for each color of dragons: Red, Blue, Black, White, and Green. Each branch has its own identity and specific task within the army. Almost any class and race combination is accepted into the Dragonarmies, with the exceptions of Kender and monks. Members of the armies may worship any evil god, so long as it makes sense, as long as they understand that their ultimate allegiance is to Takhisis.
