Rivers
Zeus, Poseidon, and Hades were overjoyed. They had won the war against their father, Kronos, lord of time. Clashing their wine cups together, to show their joy, a drop from Poseidon's wine spilt and fell from the heavens. It landed on the dry grass of Earth and became a beautiful girl. Poseidon was overjoyed to have a daughter. He named her Aqua. One night Aqua had a nightmare. She couldn't sleep. A dark voice told her to go on top a of a beautiful mountain. She traveled to the highest mountain peak she could find. It was covered in ice! The daughter of the sea god's hair turned blue from the cold and she laid there, motionless, dead from the cold. Out of grief Poseidon blessed her. Her hair grew, grew, and grew until it spread all across the world. Her hair turned into water and she turned into a fish like women. She had a scaly tail and a women's upper half. Until this day, the fish women, Nereid , keeps the rivers alive.
Snow
Long ago, way back in time, a little child was born of Isadorios and Angele, in a place with no sun. The realm of Hades. A baby that was not born, actually. Demetios was his name. Both his parents were dead, so was he, well, just not alive. His mom died when pregnant with him. He grew up as a spirit in Hades. When he reached 18, Hades told him it was time for him to be born as a living human. Demetios kept one thing in his hand when he was about to leave the underworld, a jar of water. On the way up his soul merged with the water. He turned cold until he was ice, hot so he started to melt, then cold again. He turned into something not water, but not ice. A baby made of made of Demetios' soul was born into the living. The parents, Mara and Maximos, named him Snow. When they looked at him he was not human he was a substance. Something between ice and water. They buried him far away from Greece. Snow spread through the world appearing every cold season.
