I am running a Descent into Avernus campaign on Saturday evenings. I am really enjoying this campaign. One of the current places the party has found themselves is a giant dungeon beneath a bath house in Baldur’s Gate.
Trying to describe directions in a massive tangle of underground tunnels is difficult in words. Thus, I made this map of the underground. Feel free to use it if you are running the Avernus campaign. I did leave out a couple of the completely useless rooms that I wasn’t going to include in places the players could go. You will be able to tell which ones those are if you compare it with the module.
