So, my campaign is beginning to wrap up (near the end of the school year and all that) and I'm going for the big finish. And, this scenario that we're currently in, the PCs... failed to reacquire a tome of Outsider lore. There are reasons for this failure, some even valid (like being framed for murder).
Thus, I'd like to end the campaign with a bang (or possibly a cookout *points to icon*), and I'm looking for suggestions. Right now, I have a AWOL book of Outsider lore in the hands of a Black Councilor (indeterminate shapeshifter, but definitely not a skinwalker), a failed assignment from Rashid to retrieve that tome, and an entire innocent american city.
So... should I raid the Call Of Cthulhu books for ideas and monster stats? Or maybe the tome details how to summon He-Walks-Before, He-Who-Walks-To-The-Left, and He-Who-Walks-To-The-Right, as well as He-Who-Walks-Behind? Or, or, or...
Thoughts? Suggestions? (Oh, and please no Law talk, either First or Seventh. Having those discussions in this thread would be like the disclaimers on firearm boxes that state that these are lethal weapons.)
