Moghouses/ Alliances

I want to know about the moghouses, like somewhere I heard you can biuld walls onto them, and even make houses of your own. Obviously, this is a question for beta testers or anyone who gets true info.

Also, it would be cool to help make an alliance with headquarters on each island. If anyone wants to join an alliance, I'll be searching for more information.

your house u go into an area and u load info so u go into ur house, no one can go in urs and you can furnish ur house as u see fit with things u buy.

And your second idea is not feasible, no one will go there.
