Light and Dark - On Hold

A different, far away planet called Planítis, has two sides, the Light Side and the Dark Side.
The Light Side has a leader that teaches the Light Ones how to bring everything good to Earth.
The Dark Side has a ruler that teaches the Dark Ones how to bring everything bad to Earth.
They were always enemies, but one year, the Guardians of Peace were born and would later have to go to Earth to learn how to work together with any challenge that might be brought to them.
Elafris (light in Greek) and Skotádi (dark in Greek) are the chosen ones.

*This story is not a Greek myth or legend, I just chose the names to be in Greek because I liked them.
