? Gnosies are ampliefieres to an archons power and a sign of thier elemental authority. we know exactly what they are and what they do. They were made with the body of the 3rd descender after the great war of vengance where the dragons lost agains the shades and the heavenly principles. To control the elemental power in teyvat the HP stole the elemental authoraty from the sovereigns and turned them into gnoses. After that 7 seats opened up in heaven and had the gods of teyvat fight over the respective thrones. The victors of the archon war would become archons, logically. Note that some archons like ei, never used thier gnosis, but thats just a testiment to ei's power. Gnosises can also be used for various thing like the akasha in sumeru printing money in liyue and so on.
