From the publisher:
Discover the sanctuaries of long forgotten cults with e-Adventure Tiles: Lost Temples. This 25 tile set expands upon e-Adventure Tiles: Sacred Temples by adding sections that are sinking into murky water, L-shaped sections, and sections that link to subterranean cave or dungeon walls.
Bonus tiles include sinking temple ruins and Sewer Chamber connections. Also, to make this set stand alone (no need for other Temple sets) there are five Bonus tiles detailing the Temple of the Forgotten One.
If you need a creepy temple for your favorite fantasy or pulp horror/occult RPG, this is the one for you.
