Underground Sanctuary

The  is the newest and main branch of the Sanctuary Network, hidden at an undisclosed location beneath the surface of the Earth.

Occupants
Current known residents living in this Sanctuary are all of the abnormals from the Old City Sanctuary as well as all of the abnormals from the 12 Sanctuaries Magnus had closed in 8 months between mid 2011 and early 2012; of those, specifically: Brisbane Sanctuary, Cape Town Sanctuary, Dallas Sanctuary, and Tokyo Sanctuary.

A notable individual residing at this Sanctuary is Magnus's daughter, Ashley. During Magnus's time in the past, she had interfered with the EM shield to let Ashley pass through the barrier; redirecting her energy signature to land at this location for her to rematerialize. Based on the fact that Ashley hasn't been noticeably seen topside by any personnel connected to the Sanctuary project since the Cabal super abnormal attacks in early 2009, it may indicate that she has been living underground exclusively for the past 3 years.

Building structure
Judging from what viewers can see of this Sanctuary's external design, Magnus had definitely incorporated the style of using rock as a living space for the residential quarters. A style she had picked up from Coober Pedy.

On the far rock wall in the background, the stone is heavily striated throughout with several glass-walled balconies and at least two exterior glass elevator shafts. The overhangs suggest that the majority of the rooms' actual living space is further inside the rock wall itself, with each level interconnected with many unseen internal corridors and stairwells. Several connecting windowless rooms may undoubtedly exist inside the rock as well, expanding the the total volume of the staff facility to be far bigger than what's only in view.

There appears to be a connecting observation bridge from one side of the facility to the other that spans over the waterfall.
