Humans are the only race on Lunerra that has the 'system'.
So, all other humanoid races have their own ways of becoming stronger, their own ways of using mana, and their own techniques.
For elves, it is... simple.
Too simple.
Elves are the only race that is known to be loved by mana, even though mana is known as an insentient energy.
They are born with an additional circulatory system in their bodies. And every elf, thanks to the genetics they inherit from their parents, and the mana vessels and hearts shaped by those genetics, can characterize mana just by thinking about it, without even needing runes.
They have enormous reserves and outputs of mana. And although each of them can only characterize mana in one attribute for the rest of their lives... their mastery and strength in that attribute reaches such a point that it is not a disadvantage for them.
