Aquesko is said to be one of the first Tritons to exist, alongside his sister Aquescue. It's said that they were made when the goddess Aethys laid with Sigmus in order to distract him and steal a small portion of his soul. This union infused this part of his soul into the water around them, growing golden fruit that turned into the race of Tritons.
As the God of Authority, he is said to being order to the structure of society.
He is mainly worshiped by the tritons of the Aethian Dominion, although he is generally considered a minor god below his parents.
