Mage

A mage is a high powered being that can use mana, an almost indestructible material that can simulate all types of essence. For one to become a mage, they must reach the peak of the C-Ranks, and climb the Tower of Ascension. Whenever someone becomes a mage, their lifespan will increase by about 500-1000 years.

Age
The age of a mage can tell you a lot about the mage because becoming a mage is not something you do overnight. For instance, if one encounters a young mage, they can be sure that the mage is extremely powerful because they would need to be to become a mage within 20 or so years, compared to the normal time it takes to become a mage, which is roughly 100 years. If one encounters a really old mage, they can be reasonably sure that the mage is powerful because mages don't get old very quickly, seeing that their average lifespan ranges in the 1000s of years. This implies that they have had a long time to become powerful.

Mana type
The mana type of a mage can also tell you a lot about a mage. If the mana they are using is one of the basic mana types, such as Fire, Water, Earth, Air, Celestial, or Infernal, they are not normally a powerful mage. But if they have one of the higher tier mana types, such as Creativity or Love mana, you can assume they are a very powerful mage. Since there are 13 (14 if you include Quintessence) tiers of mana, there is a lot of difference in power between a tier 1 mage and a tier 13 mage. According to Cal, 1 drop of tier 13 mana is the equivalent of a river of tier 1 mana, which really shows the power of a tier 13 mage.
