I Stumbled upon this 'Dwarf Fortress' story:
and began hatching an idea for a campaign..
Essentially this will take place centuries after the fall of the fortress, long enough for legends about it's demise to sink in and give the the fortress a real sense of peril. (fleshed out with tales of other parties/expeditions disappearances)
Our unlikely group of heroes will be swept up into a quest to retrieve an artefact from the fortress, the axe Lor used to slaughter the inhabitants of the fortress. This is to stop the axe being used as the centrepiece of some horribly dark ritual.
I've got a few ideas for some plot twists along the way, I'm really hoping for some advice on the villain though. A Necromancer is the obvious choice to me, but that's kind of my go to guy for baddies..
Any and all advice/critique's are welcome :D
