So, if I remember the world's lore correctly, magic is kind of dampened over the seas, right?

Noah's worried about someone knowing about nightmares in his head and attempting to weaponize him?

Wow. Noah is remembering names. Lets place bets if he remembers Cherry now.

Worried ? Executed !

Just dump all the dangerous magical users on a random prison island. Oh hi there Burke's mom!

Magic isn't dampened, it's just that naval travel is dangerous for everyone, magic or no, so it's seen (probably wrongly) as an "equalizer".

If anything, I would think the fact that many mages are even slightly less vulnerable in the water would give them the edge. Like, three mages with flight could basically rule the high seas, even without a powerhouse like Ariara.

@ Someone: This was actually discussed a few pages ago, with reference back to page 772 where that was mentioned & the comment section where Neoriceisgood clarified it. I was the one thinking it applied some form of direct issue for magic the few pages ago, too.

Neoriceisgood's comment from page 772:
"Nah it's simpler than that; Most mages still rely on boats to cross the ocean; blow up the show & the mage will drown just like any other person.

Like make a list of powers that would allow you to safely cross an entire ocean without severely increased risk of harm. (while simultaneously keeping access to the required food and water to survive) there's a few, but it's not a big list.

Ariara's power is arguably strongest on the ocean because it allows her to control a ship significantly more dangerous than the average one, while the number of other magic users at sea is significantly lower than on land.

Hope that explains it. :) "

Even if have flight, the ocean is vast. I don't think the average magic user would have anywhere near the reserves to cross it on their own. They'd need boats still which can be targeted then.

At least Noah is in a save spot now. Certainly there are no mysterious giant objects in the central ocean.
