Auras: In here they are a space where the user could manifest their powers.
There are different variants of auras but their base shape is a spherical nigh invisible bubble and anchored at the solar plexus of the user.
Auras could be bended into many shapes and sizes but as I said, there are different variants and some could only bend theirs in a set shape or form.
Powers: Powers could be anything and are only manifested inside auras, powers are strong in the get-go but will be stronger when users know what they could do more with it, common sense. Using a power drains mana.
Mana: Mana fluttered inside auras and the more mana you have the more you can dish out technique/powers. Mana naturally fills inside auras in time, you could better it with meditation.
There are no levels in the game only Ranks.
Ranks falls typically on the amount of mana a person could hold inside their aura.
The ranks are as below (From weakest to strongest):
1. Descent (for players also known as Stars-Descent) or Aura-Born (NPC of the game)
2. Apprentice.
3. Journeyman.
4. Herald.
5. Knight.
6. Archon.
7. Marquis.
8. Legend.
9. Conqueror.
10. Emperor.
(Ascended/Deity is rank 11) Notoriously dubbed impossible to have.
The higher your Rank, the more suitable position you are bounded to have, such is the sad hierarchy.
