Baiyue

Bai Yue was originally a swordsman who guarded the kingdom.
He believed in justice, believed in order, and believed that the kingdom would protect everyone.
Until the kingdom sacrificed an entire sea and its inhabitants for power.
Bai Yue tried to stop it, but was seen as an obstacle and branded a "traitor".
He did not choose revenge.
He simply turned and personally destroyed the sources of power that came at the cost of sacrifice.
And so--
The guardian became the villain.
The hero became the enemy.
But Bai Yue's sword never pointed at the weak.
He only cut down those who called cruelty justice.
