Oh! As far as housing goes, you can stay in the Sanctuary, that's the building you arrived in, for as long as you need to. But there's also houses in the city that are free for the taking. They work the same way hatches do–– hatches are one of the ways we buy things–– you stick your hand on the little thing out front and presto change-o, it's yours. Hatches are the same, you put the hand with the bracelet on it, it charges your account and you get whatever object you wanted to buy.
