Warring Kingdoms is a series of alternate future/universe and canonical skins in League of Legends. Set in a world where each champion is a hero or warrior testing their skills against other empires. Rival empires vie for power as they attempt to unify the lands, while brave warriors and stoic generals test their skill against the greatest heroes of the era. It is a time of war, and a time of legends.

In open defiance of her clan, Katarina has left behind the life of a princess to hunt the greatest heroes of the Warring Kingdoms. Striking under shadow of night, she is slowly cutting her way through her foes… one general at a time.
