@Salfaro Let me explain again, but im sorry if my english bad
so, first Legia say "The fact you have that power means the original owner betrayed the Rulers", its mean he mentioned about Ashborn The Owner Of the powers, And we know ashborn as shadow monarch but Ashborn not truly a monarch, but he's "The Greatest Fragments Of Brilliant Light" Or We can say The Strongest RULERS, all monarch including Legia know him as a rulers, not a monarch.
He turn himself become a monarch after other 7 Rulers betrayed The Absolute Being/God and Kill it, he decide to become a monarch and at the same time he's the strongest rulers, and then he join the war against monarch and rulers (he's alone and neutral)
so, our translation is 100% correct, idk about the other groups
idk if they didnt read the novel or smth or miss translated that part
Thanks~
