Haunted Outpost

This outpost sits on the old road between Surgeontown and the Silver Sea, now mostly overrun by Amara's Swamp. Strangely, though the sodden rot of the swamp presses close, the outpost is in perfect condition. Its walls are whitewashed, the roads neatly maintained, and even the hinges on the doors are oiled. Someone, or something, is seeing to the upkeep of the outpost.
The creature who keeps the location will attempt to enchant any who pass nearby into service. It has watched over the outpost since its former inhabitants abandoned it and wishes to see it restored to its original operation.
