The OCTOBER Jeopardy

From publisher blurb: A lost artifact from another dimension spells trouble for the heroes and opportunity for a group of terrorists. But who wields the artifact's awesome power? Are they seeking to save the city -- or destroy it? The OCTOBER Jeopardy is a short, system-agnostic adventure designed for a group of Superheroes characters. The adventure can be used with other genres with a little work; suggestions appear in the text. The adventurer also includes several character hooks, writeups of the extremist group OCTOBER, several supervillain NPCs, and suggestions for continued adventures.
