How about a vault that had only muslems in it?Like the Mormon Vault.And maby someone declared himself caliph of that vault or something?

It'd probably have to be a vault in Detroit or in a suburb like Dearborn. Outside of New York it's the most Muslim corner of the US.

I see you played crusader kings quite a bit. I should be pretty difficult for anyone to pray or make a pilgrimage to Mecca, maby they could have found a new place?

The thing about the Hajj is that there's an exception written where if there's no way to take it then you don't have to try. Presumably in this scenario it wouldn't be a big deal since no one knows in the Kabba is even still standing, or if there's a way to it.
