The idea so far about Y/N

Sadistic and cunning, Y/N is an ambitious and restless player of the Yggdrasil.

Once the custodian of countless arcane secrets, he sought a power greater than life or death, and now sustains himself by tormenting and breaking others with slow, excruciating inventiveness. His victims suffer far beyond their brief mortal coil as Y/N wreaks agony upon their souls, imprisoning them in his unholy lantern to torture for all eternity.
