Wharton Mine (Patreon)

Old Wharton Mine was a small local source of onyx in its prime, but its location deep in the jungle made it nigh impossible to maintain supply lines or defenses. In the end the mine was abandoned because of prowling beasts and the difficulty in maintaining a workforce out here.

But onyx is a troubling stone. It is the standard material component for animating the dead, and it seems some dark magic is present in the old mine as well as many chips and bits of black and white banded onyx. Now the dead crawl the mine, waiting for prey to kill and try to consume. Animals that came here to get out of the heat were the first victims, but the other beasts of the area have learned to avoid it.

Now the dead wait for those foolhardy enough to try to reopen the mine, or to claim the onyx that remains.
