What about another race of arcanists, who have allied with the other world, our world, because if 1 race/demention got there who says someone else didn't figure out to construct a breach, mabey some other type of technology made of synthesized lifeforms, living weaponry,armors, so on. I like the idea of an arachnid form(that would most likely make them nyphilim instead of archanists.) and an ridged matriarchal cast system.
