After the escape from Jakku, the crew of the Millennium Falcon are presumably in need of a place to hide out, which leads them to this temple-like building. There's a new walking droid fellow, but that's not the biggest takeaway. Although not officially confirmed, this is almost definitely pretty much the castle of Lupita Nyong'o's pirate, Maz Kanata. It's the home of travellers, smugglers, and other roguish characters, which means it's a fitting setting for Han. We don't get to see Katana here, who'll be a motion-capture character, but we do hear her in the trailer; it's Nyong'o's voice asking Rey who she is, and again with that big "The Force is calling to you..." line.
