No, actually. In the very first test (beginning of PtH 2) the group killed a creature called Caloslocke by destroying a crystal powering it. Breaking the crystal ("Orthaeur") did something to affect the binding of magic in this dimension.
I never specified what clearly, since I never talked it out with Deac
but alot of old magic powers/forces were awakened. The process is presumably still taking place, and more and more old magic should be unbound as the galaxy progresses towards its end.
Incidentally, I'd appreciate Deac's input on this. Hint hint Deac?
(BTW, this only applies to Mrearan magic, which is somewhat different from Aether magic, which is the type my characters generally use.)
