For the benefit of those who didn't read Slaves of the Dragon - the Integrators were a small faction in Eskaron's clan (and presumably others). They, like their opposite number, the Crusaders, believe that Enworld is in fact a scale (The World Scale) of a so-called Ur-Dragon, stolen by someone they call the En-Father. The Crusaders seek to return the world to the rightful owners (the kobolds), while the Integrators seek to become more of a part of the world again. There are a number of druids among the Integrators. I have at least hinted that the Crusaders aren't quite as numerous as their leaders would like, and that the Integrators are even less numerous (namely, the vast majority of kobolds doesn't belong to either faction, and may not even have heard of them). In the aftermath of Eskaron's death, the clan should have a larger relative number of Integrators, though relations with Grenton and other previously occupied towns are very likely to be strenuous - you don't wipe away years of slavery just like that.
