Melability

The magic of Candar was the weirdest one that Ning had ever come across. It was a power based on the darkness of the person's skin.

Or more accurately, it was a power based on the level of Melanin in a person's skin. 

While most other worlds had their energy stored in a core that formed in one's body, this one stored it in the melanin that was formed in one's body. 

The energy that formed was nameless. It was just so unique that people around the multiverse called it by different names.

Here, the people called energy Color, and the power one got through it is their Melability.

Ning wondered how such a unique magic system could even possibly grow in this world, only to find out that there was no energy in this world at all.

There was no origin here at all.
