Underground Sanctuary

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

History

Season 4

	Episode 4x03 - "Untouchable": After she traveled back through time, Helen Magnus realized that her current concept for the Sanctuary project would not work into the 21st century, so she made preparations to change its nature when she resurfaced from her self-imposed exile in early 2011.
	The Underground Sanctuary. Episode 4x13 - "Sanctuary for None, Part II": When the Old City Sanctuary was destroyed a year later in early 2012, the new underground headquarters was already up and running. Helen Magnus revealed its existence to Will Zimmerman sometime later (at some point within the week following his quitting from SCIU).

Season 5

	Season 5: The Underground Sanctuary was to be the primary location of the events seen in season 5.

Notes

• Trivia: It is the largest and most modern Sanctuary ever built, and is believed to hold enclosures for all of the abnormals currently under the protection of the Sanctuary project as well as having more than enough occupancy space remaining for the inclusion of many more future residents across the world that will be found and given sanctuary.
• Speculation: Given that the Underground Sanctuary obviously uses variations of Praxian technology, it is widely speculated that Helen Magnus collaborated with the Praxians during her second trip through the 20^th century; potentially even saving some of the city's population (namely, her father Gregory Magnus) before Adam Worth destroyed it.
• Trivia: The pond in the water garden / wetland portion of the environment is stocked with lots of koi fish.

Location

A deleted scene in season 4 for Episode 4x13 - "Sanctuary for None, Part II" titled: Scene 71 "New York, 1901", shows Nikola Tesla accusing Helen Magnus of hiding secrets. He recalls that in the early 20^th century she (or rather her hidden self) had him aid in the controlled usage of nitroglycerin (dynamite) to try and find a supposed 'useless' abnormal multi-headed shark in a Peruvian deep water cave - a cave that he now knows from researching the Praxian database to lead to an arterial pathway that provides direct access to Hollow Earth. This could be the real location of the Underground Sanctuary, plugged into the Praxian transport system.

• This can be supported by the fact that in 1956 a Helen Bancroft had established the Great South American Mining Corporation in Bolivia.

Alternatively, based on Abby Corrigan's research of a Helen Bancroft opening a provisions store in Coober Pedy in 1964, the location of the new Sanctuary may be in the Outback of South Australia. This area is famous for mining, copious excavation, and extensive underground living complexes of residents.

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 twelve Sanctuaries Helen Magnus had closed in eight 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 Helen Magnus's daughter, Ashley Magnus. During Helen 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 three years.

Building structure and design

Judging from what viewers can see of this Sanctuary's external design, Helen 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.

Unfortunately, there is a large flaw with the layout of the new facility as it is not very ergonomic for efficient staff mobility. This issue resides primarily with the two seperate modern buildings containing the abnormal cells, not the rock wall portion of the facility. To travel from the far end of one building to another (the ends of the buildings closest to Helen Magnus and Will Zimmerman and farthest from the back rock wall), it appears as if the staff are forced to descend and to walk on the ground level in a giant U-shape. There are no connection/platforms between either building or the buildings themselves to the rock wall. This is apparent by the external glass elevator shaft on the left side of the rock wall extending down to the ground. Without direct ease of access, travel of people and supplies between buildings would be time consuming.

• Speculation: This layout may have been intentional for multiple reasons; i.e. potentially in order to maintain the separation of certain abnormals, and security / preventative / redundancy purposes - such as if an issue ever did occur in one building that it would be contained solely to that building (hopefully just a single floor at most) and not spread to jeopardize the entire facility; leaving at least half of the abnormal cells unaffected along with the entirely of the staff area and vice versa - if an issue occurred in the staff area, that it likely would never reach either of the abnormal buildings.
