Just bought the Bat Cultist Lair to get more material to work with for the adventure I'm GMing with an old story about war between Bats, Snakes, and their cultists.

I like the setup of the location but I wouls love to have a location map of some sort to be able to build the adventure here.


Right on! Thanks for purchasing my adventure. I don't plan to make a map for this item, but when I've run it in the past I've used this map by Elven Tower: https://www.elventower.com/map-30-the-forgotten-gem/


Thank you for the link. I agree it fits the setup gracefully.
