Find the horrors and wonders left behind by the galaxy's most ancient civilizations in Starfinder Flip-Mat: Alien Ruins. One side of this mat puts heroes right into the action in a set of ruins located inside a shifting maze of high stone walls, where they'll find the hidden ruins of a forgotten culture. This side also matches up perfectly to the red planet map presented in Starfinder Flip-Mat: Planetary Terrain Multi-Pack, allowing you to create a massive encounter space. The other side of the mat shows the interior of a dark cavern filled with the semi-active remains of a once powerful alien species. Both sides can be turned into a set piece for almost any science-fantasy adventure!
