A brief introduction to the World of the Novel:

So Far the World is one identical to a traditional Western Fantasy setting however it has its own 'quirks' that sets it apart creating a 'unique identity ' for itself.

Knights appear to be the power in charge ruling through their mastery of a mystical energy termed as 'Aura' which allows them to be capable of great feats surpassing the limits of humanity in general.

For reasons unknown knowledge involving the mastery of Aura is highly classified and casual divulgence to one not from 'noble descent' or from a dubious background is a crime punishable by death .

There appear to be other intelligent races as well such as the Orcs who have carved a niche for themselves and legends of other beings have been recited and spoken of from time untold though the current status of these races is not known as well.

A brief introduction to the Cultivation System :

Based on the amount and mastery of Aura so far we observe a grouping as:

Third Tier -> Second Tier -> First Tier .

With the arrows showing the direction of increase.

Are there any higher levels ?

Only time will tell.
