Mysticana: Realmseekers

From BoardGameGeek:

Realmseekers serve as the Queen's arm, commissioning joint expeditions of newly-discovered realms. Adventurers they hire are expected to return with promising information…if they return at all. Realmseekers 6-card expansion game for the Mysticana deck and tasks players with exploring a new realm. With each expedition, use savvy judgment to assess the growing threats. The longer the expedition takes, the more threats must be overcome. Each remaining participant may use their unique defensive skills to bolster their own chances. Exit the journey early to keep what meager knowledge you have or stick it out to the end in hopes of chronicling the full reaches of this unknown land! --description from publisher
