________King and Prince

Both prince and king are Eden elder the ruler of the sky civilization, before the eden diamond wiped them out.

The king is most definitely canon, confirmed by multiple developers. The Prince's canonity is unconfirmed, but many think that Prince and King are the same person.

The Prince is possibly the leader of the elders. When the elder fell from the sky, he followed them.

We can assume that they were voted as the ruler of Eden and a monarch by the spirits (before they were spirits). The Prince became the King, and the "golden age" started

The king found the darkstone (similar to the dark plants, but is a stone) and created the power diamonds using it

The king used the power diamonds to create many things.

The diamonds contain both light and dark.

Many theorized that the king want power, or they want to return to the sky (orbit). So, they asked someone (possibly the Forest Elder/Teth) to create a giant power diamond, which we all know now as the power diamond in Stormlock Eden.

The plan backfired, and wiped the whole civilization. The elders are locked inside their respective cutscene outside of time and space while the king has gone missing.

A popular theory states that the "light" part of the king/prince is the shiny kid we saw after losing all of our winged lights in Stormlock Eden, while the "dark" part of the king is somewhere in Eden.
