I just had a great campaign idea. A BBEG sets up a bunch of small dungeons with “keys” that when put together will access his main base for the party to break into.
The twist is these “keys” have clues that just lead to other “keys” and dungeons. The BBEG doesn’t have a lair but is trying to rid the empire/continent of their best heroes so it’s easier to take over.
There can be clues for the party like groups of dead adventurers in the dungeon or an easy one like a “key” just leads back to the start of the dungeon loop again.
I got this idea after seeing a lemmy post about ant death circles.
Oh I don’t know. I just thought it’d be a cool idea and so I posted it. If I was currently DMing then I would figure that part out. Maybe the “keys” reveal details about the BBEG like they’re all of dwarven make or a certain script. Maybe one key could only have been made by some famous smith in a certain town.
