Magician

A magician is a person who is capable of using magic.

Magic
Magic is a process that temporarily overwrites a target's eidos, or internal information. The methods of using magic vary between countries, but overall, the effects of magic remain similar despite the methods.

Characteristics
A magician is a human by nature, and most of their physical characteristics match those of the surrounding environment.

Magicians age much slower than mundane humans, and it is not uncommon for magicians to live to 140 years of age. Biologically, magicians reach adulthood at the same time as mundane humans, but their period of adulthood lasts far longer than mundane humans before entering the elderly period.

Carthage Magician
A Carthage magician is a type of magician who is capable of using ether in the environment in addition to their own mana to fuel their magic. This allows a Carthage magician to use their magic for far longer than a standard magician.

Endless Zero
An Endless Zero is a hypothetical magician with the highest rank of eidos fortification at the cost of being unable to use magic. There are no known cases of an Endless Zero, though it is possible that such people might be mistaken as being mundane.
