My idea came from the premise that a genre savvy bookworm adventurer, her party, and their followers and henchmen start to realize their lives were hitting plotpoints of several stories. Then they got trapped on an island (their campaign ended short). Once trapped, they realized there was some beings above the gods playing with their lives.
Their descendants began to make make pacts with newer versions of these being: Dee Em, Powa Gamer, the Munchkin, Lil Brother, Role Playa, Josh, the Lawyer, and Grognard.
