Aaryn

As the rings and balls of the gyro-varse spin, they create a type of current referred to as the Aaryn. This current can sometimes be felt by the Shinmanaokimagi, which, with proper training, can be opened to allow Aaryn to enter into one's Trencoupention. While this process is extremely dangerous, and requires more than a few days of meditation, if successful, unlocks the ability to use Aaryn manipulation, which gives major boosts to one's soul, and therefore limitless possible power.

Aaryn Manipulation

Aaryn Manipulation is considered both the weakest and strongest magic in the universe. Everytime one manipulates the Aaryn, they run the risk of losing their soul for eternity, and it's not well documented exactly how it works or is obtained, however there are a handful of characters who have discovered how to do so, one of which is Mudakai Daikashita, who trained for three hundred years before finally uncovering it's secrets, and used it to kill William Neilsen before reading the Strikonas to summon thousands of demon-esk entities to take control over the city of Tirasheppo and therefore nearly half the power of the S.S.F.

Mudakai used Aaryn to gain eternal life, as well as the power to nulify any and all other magic. He was also able to give his followers age immortality, and buff their Eaftousias, allowing them to reach feats they'd have only just been able to peak at after decades of training.

Another person born without any Shinmanaokimagi powers, _, became adept at the use of Aaryn, although instead of using extremely powerful and dangerous techniques, he used some of the most simple spells, masterfully mixing them with his surroundings and technology to become a dangerous opponent in his own right.
