Lucid Spirit Dream Game
Purgatory is a castle in Limbo that has only fallen once. The region of Limbo has never fallen, only traded hands.
During the 5th Ango-Demon War The Accuser took Purgatory, no one really remembers how, and that alone forced the Seraphs to surrender and leave Limbo for good.
The term castle is slightly misleading. Really Purgatory is more of keep situated on top of a large mountain. However because of it’s positioning, archers and artillery seated on the walls can see for miles. It’s practically impossible to ambush for that reason.
Only wasteland surrounds the mountain that Purgatory is situated upon.
The mountain itself is known as Mount Diamant. It is an old mining territory back when the Seraphs actually had an economy. A noble demon house protects purgatory. House Searuzor.
They control Limbo with a mixed army of orcs, monsters, and demons as well. The army supposedly resides in the cliffside barracks of Purgatory.
Mount Diamant would probably take a day to scale by yourself but an army would take several.
The actual keep is carved about halfway up the mountain on a cliffside that forms a plateau so the keep can see to the North, South, and West.
There are several large entrances at the base presumably leading to the mines.
There are several smaller camps at the base as well as a small town nearby these smaller camps. The mountain is steep but a steady incline which would be a hassle to climb up, but it would be quite simple and safe to charge down.
Their is a village at the base and it is protected by a magic called a glamour which causes the village to look homely and inviting, while it sucks a visitors life force away demons run the place .
