Today, the community has discovered 2 strange audio files in the PBE server files. Based on the audio, the community believes these are voice lines from 2 champions in the Shadow Isles, Thresh and Karthus, directed towards the new champion:
A rough translation of the lines from the 2 characters is:
“They have stolen your home, Lilia. Do not forget this bitter loss. Let hatred seep into your blood.”
“The poor, lost souls are struggling to bloom… I am still waiting for you.”
With the essence of these lines, the community speculates that the origins of the new champion Lilia are somewhat related to the Shadow Isles.

Returning to Lilia in League of Legends, the portrait of this champion has been “accidentally” revealed by Riot Games with half of her face and a horn next to her cheek while introducing the new skill of Mundo recently.
Recently, Riot Games also confirmed that they would be bringing a character from the card game League of Runeterra (LoR) into League of Legends, and most of the community is focused on the name Yone – Yasuo’s brother. However, the name most likely to appear in League of Legends is Greenglade Caretaker (the title in LoR of the half-human, half-deer character):

This character embodies all the features from the face with a curved horn, half-human, half-beast closely connected to nature as Riot Games has introduced, ultimately being a character in the LoR card. Therefore, the community is confident that Lilia (Greenglade Caretaker) is indeed the new champion set to appear.
