Where Is Yahya's Secret Hideout? Not Related To "???"

So freakcrow made a video called "10 reasons to remove Yahya" and in that video he says that Yahya has a secret hideout in Dern (Dern isn't released yet so its probably the silent expanse), he doesn't show the coords. Does anybody know the exact coordinates of it?

 

Serious answer: Freakcrow is probably joking. Yahya and Dern are both memes, so why not combine the two?

As far as I know, there's no secret yahya hideout, unless there's been some secret location the whole time that no one has told me about.
