Kaitaran Temple
From Jenny Everywhere Wiki
The “old Kaitaran Temple” was one of the many ancient temples located within the Naked Jungle of Buranda in Reality Z-25 31-H.
When he came to Buranda to steal and experiment upon Solomon's Diamond, the Skull made his lair in the Temple, outfitting it with a modern laboratory for Professor Morag to carry out his experiments on the Diamond. (COMIC: Nula! Naked and Alone!)
