Immortal Peril is a free adventure for the BASH! Ultimate Edition role-playing game. The adventure is meant to introduce you to an upcoming BASH! UE product called Age of Olympus, a "Fantasy Superheroes" campaign setting. The Heroes are the powerful types you've come to recognize from your superheroic campaigns, but instead of doing battle with costumed villains atop a modern skyscraper, the action takes place in the mythical backdrop of Ancient Greece. The Heroes and Villains did not get their powers from radioactive accidents, but more likely have a magical, even divine origin. With some adaptation, just about any superheroic archetype can be re-worked to play well in the Age of Olympus setting. We've also provided four sample characters for players to choose from.
