Elder Halls

The Elder Halls are a central location deep underground within Perfect Worlds such as Freneskae & Gielinor. They contain the sleeping Elder Gods in egg form as seen in Fate of the Gods and an Anima Mundi rift.

During the The Great Revision, the Elder Gods 'hatch,' crawl to the rift, and then proceed to suck the anima of the world dry to revive themselves and destroy every planet except the one containing the current Elder Hall.

It can be deduced that the Elder Gods spend their time and energy creating worlds that can produce the maximum amount of Anima so that they can be nourished. However it is believed from Zaros' account that this is not always accomplished and that many Elder Gods die or are born stillborn from a lack of sufficient Anima, thus putting the Elder Gods & the multiverse in danger of extinction.

Freneskae
At any point in time there are no more than two Elder Halls in existence, the one in the Perfect world of the previous cycle (and as such the lowest plane of existence), and the current one in which the Elder Gods sleep (the highest plane). Freneskae being the lowest plane and Gielinor the highest exemplifies this relationship. Freneskae had its anima sucked dry by the Elder Gods, and is a wretched and desolate place. A single Elder God remains in the volcano that leads to the halls - Mah. Thought stillborn, she was abandoned by her siblings, though she survived and managed to create life on Freneskae.

During The Light Within the player brings Seren here to restore her soul with the help of Zaros. Afterwards Seren and the adventurer return to the Tower of Voices in Prifddinas.

Gielinor
At the end of Fate of the Gods, the god Zaros tasks his general and champion, the Mahjarrat Azzanadra, to find the Elder Halls of the Elder Gods on Gielinor, as he hopes to rouse them in a bid to save Gielinor from the same fate as Freneskae.
