Riot Games published a new League of Legends series exploring the lore of Varus, the Arrow of Retribution. It includes a comic and the video you can find above. Find out how Valmar, Kai and the Darkin were fused into a single being of rage, vengeance and death.
One of the ancient race of darkin, Varus was a deadly killer who loved to torment his foes with arrows, driving them to insanity before closing for the kill. Possessed of wondrous beauty, he was imprisoned at the end of the Darkin War, but escaped, centuries later, in the remade flesh of two Ionian hunters. The two men had unwittingly released Varus and now bear the bow containing his bound essence. Varus now hunts those who trapped him in order to enact his brutal vengeance, but the souls bound within him fight him every step of the way.
The development team has also shared another video in which they go into great details on why they wanted to tackle this story, and how they came up with the twists and turns for it.
