Under the ruined palace of Omu lies a yuan-ti temple dedicated to an apocalyptic god known as Dendar the Night Serpent. The temple was originally part of the palace, but the yuan-ti have expanded and modified it to suit their needs over the years. When Ras Nsi steals one of Omu’s puzzle cubes (see chapter 3 of Tomb of Annihilation), the characters must delve into the temple to recover it. Characters captured by yuan-ti also end up here.

This map was designed after the map drawn by Mike Schley (https://prints.mikeschley.com) Can be used in your campaign as needed. Makes for a good dungeon or catacomb underneath a castle or palace.
