Theories

This is a page for theories and speculation.

The Clans
It is mentioned that there are multiple 'clans,' the Sun and Moon Priests are only ever named. In Episode 27, a throne room is shown with six banners. One has the sun, another has the moon with waves under it (which has more implications, such as possible water abilities). The others have the Earth with clouds underneath, Jupiter with lightning, Mars with a sword in front of a tree, and Venus with an egg in front of it. (Although the planet is shown as blue, Mocha confirmed that is actually supposed to be Venus.)

Most of the planets and the symbols seem to be connected to Roman mythology. Jupiter was the god of thunder and lightning, Mars of war, and Venus of fertility and love. The god of the Earth was Gaia, although clouds are not connected to her power.

The wave on the moon banner suggests that Moon Priests might have some kind of water ability. That would make sense, as the moon controls the tides. The Jupiter banner almost certainly means that its priests will have lightning powers. The Venus, Earth and Mars posters are slightly more confusing.

The Mutant
The Mutant is the hooded creature that attacked Mabel and Harry. Mabel mentions that it has a 'suffocating energy.' Mocha said about it: "It's definitely not a creature that exists in our world, I'll say this at least: it's a mutation of some kind". The Sun Priests do not appear to have any kind of hold over it given that it killed a priest when he didn't recognize it and threatened to kill more. It can also sense magical energy and move extremely fast. Its motivations are currently unknown.
