Habitat
From Tardis Wiki, the free Doctor Who reference
The Habitat was location that existed outside of time and space. It was originally alien technology appropriated by the cult to Ash-Ama-Teseth. Erimem later took the technology for herself after the cult was killed and reprogrammed it into a replica of her home in ancient Egypt. After moving in with Ibrahim Hadmani and Helena, Erimem set up the Habitat behind a cupboard door in their apartment. (PROSE: The Last Pharaoh, The Beast of Stalingrad)
