In Sylvion: Below Ground, the terrain itself joins the fight. This mini expansion includes sixteen Terrain cards that occupy the spaces of the battlefield, creating new obstacles and openings in your struggle against the Ravage. Discover an Owl while placing a Tree card or Fountain and you immediately draw two cards from the Defender deck. But if you stumble upon a Swallower, it quickly gobbles up your Tree and Fountain cards before they can be placed. Enter a whole new battlefield with Below Ground!
