Ancients

"++WHO ARE YOU THAT BUILDS A HIDDEN CITY HERE IN OUR THOUGHTS?++"

- The Ancients to Mara Sov, speaking through three possessed Techeuns.

The Ancients are a group of powerful and mysterious entities known to the Awoken.

Overview
The nature of the Ancients is unclear, but they refer to themselves as being "the nothing-space fabric," and appear to be intimately connected to the space within which the Dreaming City is located.

History
The Ancients are known to have contacted Awoken civilization at least once, after the construction of the Dreaming City. On this occasion, they took possession of three Techeuns, including Kelda Wadj, and addressed Queen Mara Sov.

Trivia
The way that speech of the Ancients is written down, with double "+" signs and capital letters is similar to how the Leviathan approached Aurash, Xi Ro and Sathona in the Books of Sorrow. This can either hint against a connection between those two, or just be a developer oversight.
 * According to Shuro Chi, Techeuns wear crystals to augment their innate powers. Amethysts, in particular, is good for communing with the Ancients.
