Empire Conjuration
As magic user sects go, Empire Conjuration is far from being the largest. It has modelled itself on the Imperial Academy of Magic, and as a result has facilities scattered across the former Empire. But it has none of the resources, and has a reputation as a poorly run, second-class magic user sect as a result.
In reality it is probably spread far too thinly for its level of membership, and it struggles to keep on top of its administration as a result. It is growing, and while it could be helped by closing some of its less popular facilities, its membership is expanding, so the organisation is reluctant to close anything.
In the meantime it continues with it's scattered support for the school of Conjuration and Divination, but it also provides minor support for Enchantment, Transmutation and Abjuration schools.
