Looking for some inspiration!
My party has tasked itself with getting into an ancient vault in the catacombs beneath a palace. Anyone going in to the vault for as long as far back as anyone can remember, either never came out or came back out talking complete nonsense/utterly insane.
The vault stores an ancient artifact that will potentially be able to bring back an ancient god to life.
Complicating factor: the sister of one of the PCs has already entered the vault ahead of the party as part of a deal that saved the related PC’s life. Basically the party is mainly going in to make sure she survives, but also to help her obtain the artifact as that was part of the deal. Bad Things will happen (to the sister) if they don’t.
The setting is a bit of a mix between steampunk & lovecraftian horror. So basically there’s cults, sacrifices, gods, mysteries, steampunk-monsters (think mechanical spiders etc), machines with a lot of cogs and tubes that do stuff they have no business of being able to do….
I imagine the vault being a mini-dungeon. Say 3-4 ‘rooms’, each with some problem the party faces. I’m looking for any input for moves, encounters, monsters or traps that could be found in the vault that broadly fit (part of) the setting as described above.
