Nautilus lore

Currently Nautilus's lore goes that he was once a sailor asked by the Institute of War to explore unknown parts of the Guardian sea. The expedition lead he and a small crew deep into unknown waters. They soon came upon a dark oozing liquid, Nautilus was the only one brave enough to delve into the waters. As he started climbing in, something from the depths grabbed him, pulling him under. He grabbed onto the side of the ship just in time, but his crew was scared that he would take the ship down with him so they wrenched his hands off the side. In desperation as he sunk, he latched onto the anchor. A little bit after everything went black.

Few days later he awoke and realized the iron suit he had put on had became part of him. He was angry at the crew he trusted, had betrayed him so he started to walk along the ocean floor. He eventually came across his home town Bilgewater, but he was shunned and wasn't allowed to stay their no more. He eventually found his way into the League of Legends, where he hoped to find the crew that left him behind.

These few lines are very cool and took lots of thought, but I think their needs to be more. Maybe in some far or near future champion, they could explain what dragged him under, why, and what exactly was he made of. Also why would something just drag a person under water and convert them into a ship sized titan, for him just get revenge on some men. This I feel needs to be solved in some future champion, or a Nautilus update. As a Nautilus player and a LoL lore lover, I would love to see some Bilgewater lore updates. I know this wont get a lot of attention, but I would like too see some more lore updates.
