It's clear that since the shop is closed, something is wrong in the city. Also, Revan hinted – or perhaps just joked for fun at the expense of the expedition members – that we shouldn't linger with the demons. It's quite possible that the queen's villa was attacked/they tried to completely destroy it, and a battle broke out there. Perhaps Revan wasn't joking, but was actually trying to give us a hint that if we want to intervene in time, we need to return as soon as possible. Therefore, it would be wise for the entire party to check the queen's villa.
Where do we end up when we save the world?
