Cantona is a large village on the Wild Coast that has been taken over by the Orcs and humanoids from the Pomarj. But before they invaded, the mages that lived there created a number of antimagic fields that went awry and became a permanent antimagic sphere around the village. This is good if you're fighting other spellcasters, very bad if you're defending against orcs. The humanoids thus claimed Cantona as their own, defending it from those who would try and take it back.
