The new champion is death itself!
Listening to the champion's quotes tells you everything you need to know about it.
It often speaks of the end of life in its quotes and how all meet them in the end, and the end of life is death. The lamb represents the acceptance of death, while the wolf represents the fear of it. In the splash you can see them over a dead king, the ruined king whom has split the veil between life and death, bringing about the undeath that plagues the shadow isles. This shows that Riot still wants to keep much of the old lore still intact with this champion. Also listening to the quotes, the champion speaks of both ranged and melee combat. This means that the champion is capable of switching between ranged and melee combat. It has been revealed that Lamb is an archer, while Wolf attacks with melee.
There's more I want to say, but I think I should let other people share their thoughts. Please listen to the champion quotes and share what you think about this champion in the comments below.
