(Champion Concept) Pharone, The Son of Shadows

Lore- Pharone (Fare-oh-n), Pharone was one of the top known cat burgulars in the Shurima desert, breaking into all that there was around Runeterra but for a price. One day a man, only to be called 'Nehs', had walked up to him and offered him a large sum of money to break into The Order of the Shadows base and take a 'box'. The next day Pharone took all his supplies and traveled around Runeterra to find this base. Once he arrived he noticed ninjas had been guarding the base and he took a back route and went through one of the windows in the back of the base when no ninja was watching. He had landed in a room with only a box with symbols on it and when he looked in the corner a ninja had came out. His name was Zed. He was wondering what he was doing here in his base and why he shouldn't kill him for breaking in. Pharone had pointed at the box and said that he was paid a great sum of money to take it and return it to 'Nehs'. Zed knew who it was that contracted him instantly and threw a shuriken towards him but Pharone dodged it. Pharone grabbed the box and started running but Zed but a shadow towards him and teleported there and he ran into him and the box opened. He looked right into it and something didn't feel right. He was turning into something. Screaming he ran out of the base in an instant but none of Zeds ninjas could catch him because of his new incredible speed. He contracted something from the box, but he didn't know what. Pharone now used these powers for breaking into the highest of security places and was eventually caught. They government officials said, either join the League of Legends or Stay in prison for eternity. He chose the League of Legends.
