Riot teased their next League of Legends champion with 2 brand new videos. Before that, the new character appeared in League's official lore page. The changes there indicate that Kai'Sa is getting a new splash art with the upcoming changes. This somewhat terrifying art gives a hint to the next champ's appearance with the void aura.
In first video, the Void Empress gives a message to the Prophet of the Void, informing him that the time has come to claim the reward, which is "the end of everything".
In the second video, the message goes to the Eye of the Void. The creepy voice states: "I am the Void and I will remake all of Runterra."
The new champion is expected to arrive to the PBE servers just in a couple of days and fans expect to explore more of the new champion's abilities and storyline.
