Thank you! I love making it so that each room tells a story of some kind, and there’s a definite reason for it to be there. I guess now that it’s been brought up, I can call out a few intended spaces. Some of these details I extrapolated from the adventure Murder in Baldur’s Gate:
Edit: a few minor extra details
Huh, I guess it does kind of look like a Rimworld map. One of those built-into-a-mineshaft kinds of bases, maybe.
The secret passageway is the one next to the vomiting demon pool. You can see where it connects back to the main body of the Undercellar behind a bookcase.
But, I didn’t have a specific story in mind with the demon pool? It’s present in the reference map from Rats in the Undercellar, so I made sure it was included in this map too. But there’s lots of possibilities. The statues could be simple gargoyles, the altar to a god whose worship is approved in Baldur’s Gate (like Helm, Tyr, Ilmater, etc.), and the whole setup is primarily a study or place of relaxation. Or, given the underground nature of the worship of Bhaal or Bane in Baldur’s Gate, the upper echelons of The Guild could be offering prayers to one of them in secret, and the statues are effigies to that god.
