While the two were in fact birth-sisters, Kayle struck the first blow by disowning any filial connection when Morgana refused to join her cause. Eventually, Morgana grew in power enough to not only reach, but challenge Kayle. As the time approached when the two would meet in what could be their final conflict, Morgana was suddenly summoned to Valoran. At first, Morgana made a deal with the League's summoners to fight in exchange for greater power. With the advent of Kayle into the League, Morgana now willingly fights in the League of Legends for the privilege of being able to destroy her sister again, and again, and again. She lies in wait for the day the bonds of the Institute of War no longer hold her, and on that day she plans to destroy Kayle once and for all and return home a hero.
