Ask where you are

If you know where you are, you have a better chance of getting home.

"We're here," Therion says, tapping a map on a screen that you can't read. "A couple of days out from Helmion, where we're to pick up supplies and ship them over here, to Yukku. We'll spend some time on the ground soon; won't that be fun? If you're really good, the captain might let you come out and see the markets."

Therion goes on to explain the details of your location, but none of them relate in any way to Earth. This doesn't tell you how to get home.
