After accidentally stumbling into the Main God Space, Mu Zhi became a Chosen One who could travel only to the world of "League of Legends".
In Bilgewater's Drowned Quarter, he waited for the protagonist's nemesis from the start: a street thug trying to rob him.
In the Great City of Demacia, he fought alongside Garen to resist Sylas's rebellion.

In the Placidium of Navori in Ionia, he shouted alongside Irelia:
"Ionia, never surrenders!"
