Would be nice to have sea creatures in the game.

Maybe some giant ones swimming around and catch you off guard when you're swimming very deep.

At least a giant slaughterfish or something.

Want more Dwenmer content but are tired of the same old boring ruins?

What if Dwenmer are still alive and are living in an underwater city?

How about Aqua Dragons?

Like normal dragons but more amphibious and are only found underwater.
