I hope it doesn’t! I hope they see it or hear of it and are intrigued. Maybe they wonder if something exciting is going on there, and want to check it out.
Idk yet, but they’re probably resulting from a leak from the elemental plane of water, or a leyline nexus or something there and water magic is stronger there and so there is a flotilla of wizards trying to study it under the harsh conditions. Or it could be a hole in the world and somewhere else there is a big whirlpool, and the wrecks get spit out at the top of the water mountain and there is a whole culture of salvagers who explore the turbulence and dive for treasures. Maybe an empire of sea elves has been magically growing it for decades with the intention of using it as a weaponized tsunami so they can raid and conquer farther inland. I love irl conspiracy shit like this that asks more questions than it answers, because in a fantasy setting the answers get to be cool.
What does the top look like?
