Dresden Files: GASP
Grrrgheim, known to mortals as the Fort Pitt Bridge on the mortal side, it serves as one of the major supernatural footholds in the city, and is a gateway between Pittsburgh and the wyldfae court of Grrrg. Grrrg the Troll King makes it his abode, and the unusually cunning troll has seen his influence spread over the Steel City in recent years. Loyal to neither winter nor summer Grrrg rules his ‘court’ with an iron fist, and operates in a pale imitation of the more sophisticated realms.
At any single moment there are dozens if not possibly hundreds of trolls in the city of bridges, giving Grrrg a strong position, and only a fool would underestimate the amount of power that gives the troll king. Not only are his trolls physically imposing beasts, capable of wrecking major havoc, but the network of troll bridges means not much moves far in the city without Grrg finding out about it.
