List some champions that you would like to see their lore expanded

Okay After all of this awsome burning tides event i hve very high hopes for the future, with canonical events that actually matters in terms of champions, what they do how they act, how they interact etc.

There are some champions that to me remain pretty much a mystery, and i would like to see them a bit more integrated in the Runeterra events

Basically all we know is that he is like a demi-god appearing through history various wars deciding victories and defeats, like a God of War, he is also part of the last remaining Darkins... which i have no clue of what they are. He has a Living sword that sucks life, he is super badass and i want him more integrated with the rest of the champions.

Same story, he is a sprit of destruction or something.... then what? What is his purpose how he got here, does he have enemies or friends?

These three are more or less "elemental spirits" but... that's it. Really There is no lore to this caracters, i want to see more of them.

He is so cool, as a character, with that sexy sexy voice. But really what is he? it?. The old lore says about a man in a diving suit being "consumed" by some unamed, unspecified black ooze that we never see again anywhere in all the future champions. So he became "Nautilus", but really nothing is known of him. I personally hope that he is something that relate to both Bilgewater and the Shadow island.
