So we're doing some collaborative world building in my GURPS group. Vampires blotted out the sun for awhile, using targeted bombing to put a ton of soot into the stratosphere. Then they took over the world. Environment is still pretty dark, but not a total blackout. Other monsters used the opportunity to step out into the open too. Vampires need humans, so they haven't been wiped out, but they are mostly living in camps now.

Any setting thoughts, suggestions as to power level, etc?
