What really happened to him? If the old lore is no longer canon then there's no point in keeping secrets. I see this as sort of the thing where at the end of a long campaign the Dungeon Master reveals all and lets the players peek behind the curtain.
it is possible they just never had an answer for this in the first place and were still thinking about an answer
He's not canon, but whatever he affected beyond the league might still be canon.
Regulations dictated that League administrators could not participate or be involved in the League matches themselves, so he quit his position and established Team Solo Mid.
During this time, he met Wukong, and decided to don his appearence as a cover up.
