The foul forces of Darkmoor have amassed their legions to strike at the Capital City. Despite their well-laid machinations, something awaits them within the city walls: the realm's legendary heroes, who have gathered to council the king. Failing to siege the city, each overlord's minions must now retreat to Darkmoor lest they be captured-or worse.

In Retreat to Darkmoor!, players assume the roles of dark overlords of the realm, each commanding an identical deck of minions. Your goal: to successfully evade the legendary heroes and take refuge in the various locations of Darkmoor. Each minion that manages to escape will count toward control of a location, but beware of your so-called collaborators, as each overlord also scores points for eliminating rival minions!
