The Crystal palace the resting place of a Cosmic Elder. Deepa managed to wake the Elder and together they summoned an Entity called Creation. Creation made Deepa into a Goddess by fusing her with the Cosmic elder and giving her the keys to the Palace. The Palace held in record form the secrets of sexual pleasures and love making of all sentient lifeforms in the Universe. Deepa realized that the Weapon to defeat the Dark Ones was not military might, but the “Power of Love” and “Seduction”. To prepare for the return of the Dark Ones and the coming of the Dark One himself. Deepa founded the Order of the Sojonits.
It's now used as a headquarters fo the Sojonites.
