" I remembered how guest rights worked from our last time in Jotunheim. If you made it inside the house and claimed you were a guest, supposedly the host couldn't kill you. Of course, when we'd tried that before, we ended slaughtering an entire giant family after they attempted to squash us like bugs, but it had all been done with the utmost courtesy. "

― Rick Riordan , The Hammer of Thor (Magnus Chase and the Gods of Asgard, #2)
