Battle Map Descent into Avernus Doctor's Stash Dungeon

Content

Hey everyone!

The hand on the altar opened, revealing the passage into the High Hall Catacombs.

As your party descends further into the mysteries of destroyed Elturel, they see weak torchlight. Frightened people hide behind the sarcophagi in the stone alcoves, blood and bones everywhere. Everything is evil, yet they sense the calm amid calamity, as they find survivors. Although scared and rattled, they didn't give up to the chaos.

Important: The catacombs, like cathedral above, are massive, and it would be huge (in terms of file size and loading time) if the squares remained the usual 140px per square. I reduced the size to 70px per square, so keep that in mind while loading it into the VTTs or printing it. Also, the catacombs are part of the Cathedral FoundryVTT module as one of the levels. I reuploaded the module with new content.
