~Aspects~

Sentient representations of concepts. The rarer an Aspect is, the more powerful they most likely are.

For example, there are many Flame Aspects that exist, and possessing a Flame Aspect grants you the power of flames. However, there are also fewer Aspects, like Gravity, Light, or Darkness, making them rarer and more powerful.

There are Nine Primordial Aspects that exist in the world. Only one of their kind exists, making them extremely powerful.

PS: Very little is known about Primordial Aspects.

It is possible for an Aspect Host to possess more than one Aspect, but Aspects usually demand something in return for being used, so Hosts must be careful not to bite off more than they can chew.

'The Price' is what connects Aspects to their Hosts, forming a bond that must be mutually agreed upon.

Aspects can not maliciously harm their Hosts, and Hosts can not maliciously harm their Aspects.

They are bound together by the Ancient Records of The Antecedent (The System).

~Essence~

The fuel that acts as energy for both the Aspects and their Hosts. Hosts use Essence as energy in order to use abilities: Magic (for Mages), Martial Arts (for Warriors), or both.

Aspects are built up of Essence, which is essentially pure energy, and this energy manifests as their respective concept, e.g. Fire Aspects use energy to produce flames and are made up of flames, etc.
