The Second Dark Legion War has escalated to encompass the entire solar system, with humanity hard-pressed to hold back the swelling tide of Darkness. A surge of Heresy has stretched the Brotherhood to the breaking point, while the megacorporations are throwing a rising body count into the ever-hungry maw of the Dark Legion. A slim chance of salvation leads the Cardinal to call upon the heroes of yesteryear and task them with uncovering Ancient technology that will turn the tide of war in humanity’s favour. Technology that is hidden on humanity’s former home, Dark Eden. The Dark Eden Campaign is recommended for experienced players. Designed to bring the events that began with the Dark Symmetry Campaign to a climactic conclusion, suggestions are provided on how best to update the timeline or incorporate this into an existing game.
