Yorick's current role on the Shadow Isles does not seem like it would fit in the current lore.
He was suppose to be the ferryman of the Shadow Isles. This role was to help other dead people climb the ladders in tiers of power. I'd assume that means one form to the next. But I thought about it, why exactly would the SI need a ferryman when they have morde who can seemingly grant such power. As he did with his sorcerers. He's also the "grave digger" I do not understand why they would need that role there also. The King and queen's remains must still be near the Altars for them to be bound to them. Wouldn't grave digging be more a necessary thing for other none shadow isles? What graves are there to dig when there was a order there instead of a kingdom? I don't find it too likely that they had a cemetery there.
In this current lore, what defines Yorick as a character? Did he possibly still attempt to find his body? What about his family's business? This have me worried about the "extra" characters of the shadow Isles. Did Elise walk the lands of the isles alive and returned to Noxus also w/o dying? Who is Evelynn?. Things like this needs to be addressed. Yorick is too much of a good character to just leave him as he is.
