Kâsdejâ

The original city of the dead, Kâsdejâ was a secret layer of reality deep in the bowels of the world constructed by the Slayers after the rebellion against Heaven. Barred from the land of death and uncertain as to what was being done with the souls of mortal dead, the Slayers created a beautiful fortress filled with the manifest memories of dead plants and animals where mortal souls would be kept safe from the angels. It served as the secret headquarters of the Alabaster Legion for a time, but eventually was discovered by the Angelic Host. After a difficult battle expelling the angels, Azrael and Charon decided that another deeper realm had to be created if the mortal souls were to be kept safe, leading to the creaton of Haven. Kâsdejâ continued to serve as the home of Azrael and the Alabaster Legion, and was later conquered by Lucifer as part of the Long March. This violation led to many Slayers abandoning the rebellion for Haven.
