Expanded Lore

I recently found out about the expanded lore on wiki page. http://leagueoflegends.wikia.com/wiki/Karthus/Background http://leagueoflegends.wikia.com/wiki/Lucian/Background

I'm not really sure when this was posted, and I'd like to know if any other champions have expanded lore. I'm not an intense lore fan like many here, so I'm actually kinda happy with this much of lore. I am not satisfied with just a few lines of lore (like Azir, Amumu, or Rammus), but I'm okay with this. I hope at least to some of you this is new, and enjoy this extra bit of lore not found on client.
