Species

Also reffered to as draconequui 

(not all of them are draconequui but all draconequui are primordial spirits. Draconequui are not a subspecies or anything but some of them may be reffered to as that.)

In the newborn world created by Mortina and Akasha, new aspects of the universe started to contour. Things that can only exist if there is life, things that once there was life will forever exist. Chaos, Malice, Luck... those are just a few of them. Once one was born, a new spirit - a God - took birth. The spirit of Chaos was Discord, the spirit of Malice was Cosmos, the spirit of luck and fortune was Eris, and many more. Those were called the Spirits (or Gods) of Life.

In the first days of this world there was a storm of magic and Being in which all things took birth above this New Earth, and those spirits haunted the world. It all went so fast and as many as took birth in that moment there died, only few have survived and now they’re part of the nature of the world.

In the Grifixverse, draconequui are primordial spirits associated with concepts (like chaos, malice, luck etc.). 
Any primordial spirit must have a concept associated with them and a name that represents that concept (it is encouraged that you pick a mythological name).
These beings are older than earth, so they can not represent something that exists because of earth, like nature. They can represent things like growth, flourishing etc. which can be for a spirit associated with nature.
A concept is an abstract idea, and can not be broken down into other concepts (your “concept’ will need to be approved before you are allowed to use it, just to make sure it is a proper concept).

When they were created, each primordial spirit/draconequs had their soul linked to a celestial body from the Solar System (planets, dwarf planets, satellites, meteorites, any celestial body). They had domain over those celestial bodies, but that didn’t mean they resided there or anything. But they had power over those celestial bodies. 

Following a great war most of the celestial bodies in the Solar System were destroyed, and the primordial spirits were stripped of their ownership and powers above them. The only one remaining is Discord's planet - Earth, but he has no more power over it. He was by no means the strongest, but he is the only one whose planet remains.

Because the solar system remained empty, it is only a matter of perception about who orbits around who - viewing the world with earth at the centre, it is possible to see the sun orbiting Earth. So in this world - while their orbits are the same as in reality, the Sun is orbiting the Earth - or so it is perceived. 
Relative to the Earth, the Sun moves on an ellipse - which has two centers, one is the Earth and the second is "Neant". Neant is the opposite of Existence, an all powerful being. It is in the parallel realm of Neant that certain things are set in, such as fantastic beings, spirits, souls, or even the sphirix.

Appearance

Primordial spirits can have any appearance. 

Some of them are draconequui and look similar to Discord, Eris or Cosmos but there is no rule to their appearance.

Bases/references

There are no bases, if you want to create such a character it must be drawn in a style as close as possible to the mlp show style.

For that just provide a sketch/old design and ask MysteriousShine to make a sketch you can use as a base for the reference.
