Lore

The day the Noxians invaded my village I was weak and cowardly. As they slaughtered my friends and family I ran.

Initially, I sought vengeance against those that wronged me, however, after I had completed my training, my path of enlightenment if you will. I had realized revenge would not soothe the wounds that ail me, but instead it would throw me further into despair.

My pursuit for this enlightenment took me deep into the mountains of Ionia. Where you can almost hear the wind whisper the secrets of the world. Eventually, I stumbled upon a lake that seemed to call to me. It was here that I trained sharpening my mind and my swordsmanship. Legends seem to say that similar pools found in Shurima could give one powers beyond their dreams… But who would believe only Legends?

“Why did I join the League then?” is what you are wondering I presume. I joined the League to further hone my skills, learn about the vast expanse of intriguing subjects, and of course to represent Ionia on the world’s stage. However, I do often wonder if a particular swordsman has truly been appalled by their old ways. If they have truly left Noxus for their own good… Or maybe their own gain…

“Everyone has limits, whether they choose to abide by them is a different story.” -- Aidin
