I have a theory.

Idk if someone said it earlier but in the trailer we can find this kind of “wolf” appearing with great importance, and we can see that Vlad is concerned about it, but LeBlanc finds it useful. SO i did my research because i remembered something, in Convergence: A League of Legends Story there is a letter, where it lists primordial demons, such as fiddlesticks but we don’t recognise two of them (i’ll send the pic). MY THEORY the demon is actually the primordial demon for Rage or Surprise. Because in the letter is depicted as a hyena, and the symbols around it are similar to Noxus demonology. Tell me what you think
