Note: This faction is intended more as an element of one adventure than a long-term ongoing faction.
Kids in the nearby village of Willowbrook often dare each other to enter the Caves of the Dead. The passages seem to twist and turn forever in a confusing maze. Here’s a good map.
The Caves of the Dead do actually contain the dead: several chambers contain simple sepulchers and stone tombs, installed by locals many decades ago. Modern residents use a nearby graveyard “like normal people,” so the Caves of the Dead are rarely visited, except by those kids on dares.
But things have changed recently. Those kids now claim to have seen ghosts appear and cry out, asking for help.
Little do they know, a necromancer secretly entered the area recently and has disturbed the spirits.
As a friendly faction, the spirits haunting the Caves of the Dead are trying to warn the residents of the necromancer, and can guide PCs in finding old weapons or preserved magical artifacts to defeat the necromancer, as well as point the PCs towards the necromancer’s location deep within the Caves.
As a foe faction, the ghosts in the Caves of the Dead are the necromancer’s unwilling pawns. He’s installed himself deep in the cave, and the PCs will have to fight the ghosts, plus raised skeletons and zombies, before confronting him. However, the ghosts will answer the PCs’ questions while fighting.
