Okeanos was a powerful and important deity in Greek mythology. He was responsible for the creation and maintenance of the world's freshwater supply, and he played a role in the regulation of the cosmos.  He was also known as Oceanus, the primordial Titan god of the great, earth-encircling River Okeanos, the source of all of the earth's fresh water. He was also the god who regulated the heavenly bodies which rose from and set into his waters. Okeanos' wife was Tethys, the Titan goddess of the sea. Their children were the Potamoi, gods of rivers, and the Okeanides, nymphs of springs and fountains.

In Simanity, Okeanos assumed the same role and temperament and ended up with the same fate with a few twists to suit the story I had in mind for Simanity.

Metis was the goddess of good counsel in the Greek mythology.  In Simanity, she was the first born child of Tethys and Okeanos.  She married Zeus with whom she had a daughter, Athena. Hera, one of Zeus' many wives, was so jealous of her she ended her - a different story than what was in the Greek mythology where Zeus swallowed her for fear of being overtaken by the child she was carrying inside her.
