How about a non-malevolent character from the Shadow Isles?

I was just feeling that riot could add a little variance in the shadow isles motivation. The point being that besides Maokai, champs from the shadow isles seem to be motivated in some part by death and destruction. If you consider the fact that most were at some point human there should be at least a few who weren't completely broken by whatever turned the isles.

There should be a character who turned all the anguish it felt into a overtly friendly attitude to cope, maybe with a prankster penchant. Think Casper the friendly ghost meets Peeves the Poltergeist from Harry Potter.

I think that could provide much insight as to what turned the isles and what it was like in the past in future lore.

Edit: Many have pointed out Yorick as a non evil entity, but at best he is neutral and most of his lore will most likely be significantly different once his rework has happened.
