The Shade Isle Campaign
This area of the Merkbog contains a raised patch of dry ground with an ancient, long-forgotten graveyard. Whatever town this graveyard once served is long since sunk into the swamp and lost to the mists of time. The graveyard itself is surrounded by a wrought-iron fence rusted almost completely away, and all of the lapidary on the headstones (to say nothing of the faces of any statues remaining here) is worn down to nothing. A partially-collapsed mausoleum stands in the center of the graveyard.
Practically every corpse in this place had become a ghoul, until the adventuring company came through here and cleansed it with extreme prejudice (namely by judicious use of Connor’s power to destroy undead).
