The PCs are likely are going to try to get into a safehouse of the local thieves’ guild in the next two sessions. The setting is Ptolus, using the D&D 5E rules.
The safehouse in question is in a lower middle class region on the surface, but it has another entrance to the vast dungeon systems beneath the city. This, in itself, is not unusual - the bedrock on which the city stands is filled with tunnels and long-forgotten vaults. But while most house owners just try to brick those passages over, the thieves’ guild actually uses these passages for their business dealings.
And I need some ideas on both what might be inside the premises, and what kinds of systems they use to secure the safehouse. The PCs will likely be coming from the “dungeon” side, and this is the kind of city where criminals expect inconvenient adventurers to pop up in all sorts of places.
I’ve already determined that the location includes:
- a vampire ally of the guild
- some cells for prisoners who get interrogated for information
- a bunch of drugs for resale
Any other ideas? The party consists of four 8th level characters, if this helps.


Stolen goods that they thought were valuable, but aren’t actually.
Complete with exorbitant prices and backstory. Make it obvious that the seller is delusional and just steals random shit and tries to resell it with a made up backstory.
Make the other theives dislike the seller and if the PCs ask, they say the dude is probably off his rocker. “He ain’t good at theivin’, but he is the nephew of important person” or “he is a really good cook, so we keep him around”
Bonus points if you conceal an actually useful item within the midst of garbage
