Event Horizon is a mixed series of alternate future/universe skins in League of Legends. Set in the vastness of the cosmos, each of the champions represent cosmic ethereal beings able to bend and shape the universe with their will. In the vast darkness of space are born terrible, beautiful things—Cosmic creatures of sublime love, and the unknowable monstrosities of the Dark Star. These are the children of silent gods, and they are finally coming home. Event Horizon officially encompasses two skin lines: Cosmic and Dark Star.

Once a cosmic entity charged with identifying future threats to the cosmos, her hunger for ever greater knowledge drew her into conflict with the Dark Star, which consumed her. Transformed into a mad doomsayer who sees a “true” universe in the ashes of this one, she has become the very end she once feared.
