Mygaria

Mygaria is the name of the ancient, mythical entity and a holy temple of the Primera, residing at their capital, Myggo, in a hidden location somewhere at Khalios. It is a key subject of the Primerian culture, and their descriptions of it exceed even Theian achievements.

The Temple
As told by Pamma the Switchblade, who went all the way even to Gerontas along with a few other Primera to settle a new city there, as he told the Aesarian king about Mygaria and Mygga:

"Mygaria, the Living Shrine and Temple of Eternity, stands on the center of Myggo, the Eternal Metropolis. It's towers are hands holding the stone sky from falling, and it stands high, watching over our city. Inside it, it's massive, astounding clockwork mechanics give it life and a consciousness, and we have brought it countless amounts of information, so it can teach our wisest ones to convey it's wisdom to our people. The most ancients built it to resemble god, and all gods to come. They sacrificed... a lot for it. One day, it will uproot from our city as a true God, the omniscient and thus, omnipotent. When? Soon enough."

No other rational description has been heard after this, no even by the Dyankhir at Khalios. Between lines, it could be theorized that Mygaria is actually a clockwork robot, built to 'resemble all gods'. The Primera believe that 'knowledge is the basic ingredient of everything', and thus, they seek to create a physical god through teaching it and filling it with information and wisdom. It is unknown how intelligent this robot actually is, although even the wise Primera worship it, which could hint about's it's wisdom. The clockwork mechanics that were spoken about could also hint they used similar technology as Theians did.

The 'God'
The Primerian are very strict of their religion, and are unable to follow any other pantheon than their own or share their own religion with other races. It is known they only have one god, Mygaria, meaning knowledge or mind. They believe Omniscience is the ultimate state of life, and that is when a person becomes a part of Mygaria. Mygaria himself is told to be more like a thought than a being; it exists because they (Primera) made it exist, and it represents the ultimate state. This is what the temple is to become.
