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 A special coating on each Flip-Mat allows you to use wet erase, dry erase, AND permanent markers with ease Removing permanent ink is easy-simply trace over any permanent mark with a dry erase marker, wait 10 seconds, then wipe off both marks with a dry cloth or paper towel. Each Flip-Mat measures 24" x 30" unfolded, and 8" x 10" folded.
