"Not much beside being less than 20 feet away from us, really" Ezra explains "We will be sending purified magical energy at your direction for about twelve hours, maybe ten, it is not complicated but requires focus like walking non-stop on a narrow hallway without touching the walls... after nine hours we ought to be too exhausted to do anything more complicated than sitting so we should rent a room or maybe go outside and away from people. We will need rest for at least two days and since the door is not time cooperative at least one of you should stay in Milliways, we will pay you reasonable room and food for one or all three of you. Me and my siblings should experience about ten Milliway-days, maybe twelve. You are invited to consider this a bizarre impromptu vacation on a multiversal bar."
