Pride and Possession: The Bone Wars

From the introduction:

This a high-energy comedic free-form LARP about academia, ghosts, dinosaurs, and interpersonal relationships. Two players will play ghosts of feuding paleontologists, trying to settle scores via possession of the living characters. Four players will play members of an university paleontology department, squabbling over typical academic issues. No facilitator is necessary. There will be approximately 45 - 60 minutes of work-shopping and 60 to 90 minutes of play.
