Saekoll's Demiplane is a demiplane created by Gavros Saekoll for the purposes of continuing his research into teleportation after the initial failure of the plagues of Erenon to capture enough souls to restart the teleportation site under his manor near Restone.
The demiplane takes the appearance of a large torus. In the inside of the torus is a faithful recreation of Saekoll's manor and grounds, furnished in exactly the same manner and patrolled by the same construct guards. Vegetation - grasses, trees, and shrubs native to Erenon - grow in the inside of the torus as well. A sun-like light hangs to one side of the otherwise black sky, bathing the area in permanent daylight. Around the outside of the torus, the surface of the demiplane gradually becomes extremely barren until it is nothing more than smooth, solid stone.
It is unknown when precisely Saekoll created his demiplane, but it was in place by the time he unleashed the plagues that devastated Erenon. After it was clear that the number of souls collected via this manner would be insufficient to provide enough magical power to restart the teleportation site upon which he had been experimenting, Saekoll retreated to his demiplane to continue his work. By varying the passage of time in his demiplane, he was able to extend his lifespan relative to time on the Material Plane, while simultaneously allowing himself to choose an opportune time to become involved in Erenite affairs and set his plans into motion once more.
