It's a matter of fact that Nyarlathotep's power is unparalleled. And as the soul/servant of a mindless idiot god, he has much much much much MUCH a desire to screw around with the cosmos. He's worse than a Q, even John De Lancie. He's like a Q that gets exceptionally bored, hates his existence, and hates you too. Welcome to hell as told by Lovecraft.
