Castle of Skulls

The Castle of Skulls was an abandoned castle built entirely of skulls, located in Llyrath Forest on the island of Gwynneth in Moonshae.

Location
The castle stood in a stagnant fen in Llyrath Forest near the rugged, rocky southern coast of the kingdom of Corwell in Gwynneth. It was cloaked by weeds, making the task of finding the castle a quest unto itself, let alone conquering the horrors to be found within.

History
The exact date of the construction of the castle was not known except that it was built after the reign of Cymrych Hugh to celebrate an epic battle against the Northmen in which the Ffolk were victorious. The fortress was raised by High King Gwylloch using the skulls of all the enemies of the Ffolk who had fallen in battle. Gwylloch was so impressed with the morbid pile that he made it his permanent residence and continued to augment the cranial citadel with the severed heads of all who opposed him.

Eventually, however, the sinister stench of death and decay drove Gwylloch and his court insane, causing all of them to turn on each other with murderous blood frenzy. From that point on, the hall of the dead was never more inhabited by the living.

Inhabitants
The upper floors of the castle were infested with monstrous reptiles including basilisks, giant snakes, and (it was rumored) a green dragon. The subterranean levels were haunted by powerful undead that guarded the buried remains of warriors, knights, and kings with their rich and magical treasures. These undead included ghosts, spectres, and a lich.

Rumors & Legends
As of 1357 DR, it was thought that somewhere within the castle was hidden the unholy artifact known as the Cauldron of Doom.
