If one of more Ruins cards are revealed, each player must draw one of the available Shapes, depicted on the next Explore card that will be revealed, so that ir overlaps a Ruins space on their map (if possible).

If a player cannot legally draw one of the available Shapes so that it overlaps a Ruins space OR there are no unfilled Ruins spaces left on their Map, they must instead draw a 1x1 square anywhere on their Map and fill it with ANY Terrain type.

If an Ambush card is revealed immediately after a Ruins card, the Ambush card is resolved normally. The Effect of the Ruins card will apply to the next Explore card that is revealed.
