Although the technology was somewhat basic, diving equipment had been around since the time of Alexander the great. I think SoT could introduce something like a diving bell to take players to the bottom of the sea. Id love to see the typical helmets but they were a bit more modern....
This concept could be used for a number of things, tall tales, shipwreck recoveries, Hunter's call voyage and could even be the introduction of any mermaid based updates to come.
Enemies would of course involve sharks but maybe even skeletons and sea snakes and maybe some passive bottom feeder creatures too.
