Elf, was an big race in Valoran in the past, they had high connection with the nature, what they liked were peaceful and freedom. But because of the continuous wars and the abuse of magic power, the nature was badly affected, and the elf started to leave Valoran. Rena, a elf, woke up in idyllic forest one day, but she lost most of her memories. She only remember that idyllic forest was a green and beautiful forest in the past, but now it was seriously polluted. She sorrowed about that, and she wanted to save the nature because of her instinct. She started to contact the sources of pollutants, the human.
And summoners were also curious about her, but they could not catch her, because she was a Wind Walker. Rena still remembered all of the skills of Wind Walker, which was a strong class in elf, who could get the power from Wind. At last, Rena still meet with summoners, and she know that it was impossible for human to totally stop using dark magic, but the summoners promised her that if she agreed to join the League Of Legends, they would help to stop the wars and reduce the abuse of magic, which polluted the nature much.
