Haha, maybe, but there's gotta be some element of chance in there, I'd think. Otherwise, there'd be too much power for trolls to just build massive, super-powerful brains in someone's base to throw their entire system into anarchy. I say, instead, we have Brain Wars, where multiple, competing minds send their various implements and things against one another, and if one gets their (literal) tendrils into an opposing brain, they take it over.
"Warring Brains." Sounds like a good name for a metal band.
