I've heard about that thread, never bothered to read it fully.
I speak about the lore. Not my own opinion. And an alliance with a collective of Mahirim? That's beyond pushing the lore, that outright shatters it, it flys in the face of all the racial tension. Again I say, there's plenty of racial tension with dwarves/elves already from a lore standpoint, a mahirim? What's next, alfar? Demons?
