The Cult of Erda is a narrative micro-campaign for the Vastarian setting (which is being developed by the folks at Between the Bolter and Me blog). This booklet contains three scenarios, as well as some narrative prompts and information about the setting and environment.
The Cult of Erda sees your own cult forces descending into a bleak forest wetland in search of an ancient shrine to Erda, the mother of humanity. Confront other believers and prove your worth to the holy mother.
This booklet is system-agnostic, and should work just fine with any sci-fi skirmish games (or fantasy skirmish games, if you bend the narrative just a bit).
