Er, why Settra. Like... Settra's not even remotely a good choice because the armies aren't derived from his abilities so much as he'd have to be brought here along with [i]half of Khemri.[/i] I'm not the GM but it doesn't seem like whatever's bringing people here is going to be so broad as to transport entire armies inexplicably? 

And... that sort of scale is probably too large and he'd just get carpet bombed by the nearest military.

I guess he came to mind because of the Total Warhammer preorder?
