Renzhe, The Sword of stealth

hi it's another champion concept... anyways...

Renzhe, the Sword of Stealth

Renzhe is a squishy melee assassin mid/top laner that trades fairly well early game and gets most of his power at level 6.

Lore:
Ionia, deep in the mountains, lay a dojo, one similar to shen's, and zed's. There stays a boy, names Renzhe, a powerful child, with the mind of a genius, and the physique, of an assassin. Renzhe has several dreams of becoming a ninja. Renzhe relentlessly trains everyday, and never improved. He obtained several swords, trophies, and other accessories, but it never helped him. One day, at night, Renzhe was training, and saw a green glow, far away. He followed it. It led to a temple. This was the same temple Zed had went to to obtain his dark powers.

  Renzhe always had the urge to become an evil being of darkness, and this was his chance to become that. Although, everyone knows what comes power, comes a cost. Renzhe walks into the temple, and within seconds, Renzhe fell to he floor, lifeless, and as if he was dead. But he wasn't dead. The Dark powers inside the temple had drained his life force, to create something that would corrupt Renzhe's soul with darkness. It was a sword. It had a sleek black paint, with the edges painted a clean green. Renzhe had discovered that this sword is extremely light weight, and he felt powerful. Although, Renzhe did not know what had empowered his soul from that day, but he was corrupt, and lead on to several killings, and murders. He is never seen, or caught, and no one knows what the power was, of that sword.

"This sword is the beginning, and the end."
