"Uh, okay," he says. "Short-range teleportation spells will take criteria like those first ones - I did one to take us as far from people as possible. But they won't take you to another planet; I'm not even sure they'd get you to another continent. Dimensional transfer and long-range teleportation need something more precise. Coordinates aren't relative to your starting position. I can feel coordinates, and I'm pretty sure you can't, so I genuinely have no idea how to get you to work a dimensional transfer spell that's not random. And the random ones will take some environmental parameters, but I don't know what all the parameters are for an environment that won't kill you on the spot."
