The Eldunari

(In progress)

The Eldunari is a very special room that serves as the central nervous system or heart of the entire Warehouse. Adwin Kosan said "the Eldunari connects the mind of the Caretaker to the soul of the Warehouse". It is filled with floating symbols (mostly Norse runes) constantly moving in all directions.

If the symbols are moving in perfect harmony then that's a sign the Warehouse is happy and healthy. If something is wrong with the Warehouse, the Eldunari will reflect this by the symbols moving irregularly and being destroyed.

History
The Regents suspect that the Eldunari was created by the Warehouse itself. . ..

The Eldunari was first discovered on January 15, 169 C.E. by Regent Anne ÆÐELÞRYÐ after the death of Caretaker Flavia Prisca.

Location
Originally, the Eldunari was located as a room on the main storage area for artifacts, located a few dozen feet away from the main office. After Warehouse 4, however, the room became inaccessible from the main floor. It was accessible through a door in the main office, with an artifact being necessary to change the doorway's location from a storage room to the pathway to the room. During the time of Warehouse 7, Genghis Khan moved the room again after an incident with an enemy spy. It was because of this incident that the Restricted Files Room was created, and the entrance to the Eldunari was moved so that it could only be accessed from within that room.

Canon History - Warehouse 13
In the episode "All the Time in the World", the Warehouse's computer was operating at a much slower pace than normal and Mrs. Frederic began showing signs something was dreadfully wrong. Mr. Kosan and Artie went to the Eldunari to see what was wrong, Mrs. Frederic's mind is a reflection of the Eldunari which means if something is wrong with her than something could be wrong with the Eldunari and thereby wrong with the Warehouse as a whole. Mr. Kosan and Artie noticed that some of the symbols in the Eldunari were moving in an irregular manner and being destroyed.

They didn't know what this meant until they discovered Paracelsus was Caretaker of Warehouse 9; the Warehouse can only have one Caretaker. When Paracelsus was debronzed and because of his former Caretaker status, Mrs. Frederic's and Paracelsus's minds fought for control over Warehouse 13, which was tearing the Warehouse apart from the inside-out.

In "The Truth Hurts", Pete and Myka captured Paracelsus and brought him back to the Warehouse. Pete used the Philosopher's Stone on Paracelsus thinking it would make him mortal again, but what Pete didn't know was when the Stone is used on a Caretaker while they're near the Eldunari, the Caretaker's connection to the Warehouse is increased to the point where they can conrtol every nut, bolt, and artifact in the Warehouse with just a thought. Claudia disconnected Mrs. Frederic from the Warehouse using the Caretaker Ribbon, since Paracelsus had grown so powerful his mind would have killed hers.

In "Endless Terror", Artie learns from Abigail Cho that currently there's a large ring of fire spinning inside the Eldunari because Paracelsus' connection to the Warehouse is stronger then any other Caretakers in the past. Artie intended on using Sargon the Great's Mirrors to reflect the fire back into its four alcoves where it belongs which will also cause the Nordic symbols to reappear. As soon as Artie restored the Eldunari to its former state, Paracelsus' connection to the Warehouse was broken.
