Ceithre Seasuir (English)

In the beginning there was only four. Four beings, they were known as "The Creators" of our seasons, the creators of all. Gods to the human race.
Good will and hope was spread throughout the lands with them there, but soon a demon named Amhain got into their minds, making them create things they did not wish to be there. Everything the four had begun to build was being destroyed by Amhain. So they had to make a decision. They decided to disappear from Earth for many years, Amhain at their rule, until one day they could come back. Till their power was at it's strongest, and Amhain could be taken down.
Only problem is, once they come back to the world they created, they do not remember who they were and what they're brought back to do.
