Not only it is a legitimate rumor but it’s had a lot of backing in blue sky development with quite a bit of leaked artwork floating around.Can we please stop bringing up the idea and rumor that Legend of Zelda is going to take over Poseidon's Fury/Lost Continent?!?! That rumor was likely killed in the pandemic, IOA already has a castle-esque building (Hogwarts), and changing LC would be doom for Myhtos Restaurant, which is very popular.
Additionally: who’s to say Mythos couldn’t be rethemed to match the area in a way that improved upon it?
