Every living being that focuses on training its magic power has a core with a different colour. For example, Rossweisse has a purple core. The purple colour of a Mana Core represents a symbol that a person already possesses mana power equivalent to that of top-level powerhouses.
Beginners who have just started their Path of Magic generally only have pale white Mana Cores within them. For that reason, I currently have a yellow Mana Core within me.
The yellow colour represents the quality of a person's Mana Core as a Superior Mana Core. Meanwhile, the white colour represents the Inferior Mana Core. Therefore, it is not strange that all living beings who have just entered the Path of Magic have Inferior Mana Cores that are extremely low and worthless.
Only those who have achieved a Low-Grade Mana Core can be considered true mages. As for those who have an Inferior Mana Core within them, most of them will be considered lowly mages without any qualities for their entire lives.
