Rhongomyniad Mythos: Tower of Dreams Founding the Ends of the World (最果てにて礎なる夢の塔(ロンゴミニアド・ミュトス), Saihate nite Ishizue naru Yume no Tō(Rongominiado Myutos)?) is the true function that Rhongomyniad was made for, the ability to anchor the world in place. Gray unlocks this ability three years after Case Files.

There is a world of fantasy, dreams, and myths that Rhongomyniad keeps pinned inside the Texture of the world. With Rhongomyniad Mythos, Gray can contain Mystery and make sure none of it leaks outside.[1] A seal of Rhongomyniad Mythos's power is rare even for the Age of Gods. Without outside intervention it could take over a century for the effects to wear off.[2]

When the light of Rhongomyniad Mythos pierces Bai Ruolong, the spirit of Typhon inside him is "anchored" and Ruo's wings and Blaze of Etna armor that he gained from Typhon disappear, preventing any of Typhon from leaking out and preventing Bai Ruolong from using Typhon's abilities.[1]
