At the spur of the moment, I ended up running a Pathfinder game last night. The whole adventure was completely improvised and I was able to use some of Paizo's GameMastery products. The Chase Deck (it's ingenious) and the Enemies Deck in addition to their Flip-Mats made several ideas work out great.
By the end of the evening, a new campaign had taken shape, with the players apparently caught up in the Blood War. It appears that I'll be running this further. Currently it appears the player's are caught up in the machinations of Pale Night (the Brotherhood of Bone and Teeth) and Glasya (the Sindycate).
I promise to finish posting session overviews for Primeval Session 1 and Gathering Session 5 soon. I'm prepping the Marvel Heroic Roleplaying Game for monday night and I've named it Mightest.
