Alright, I guess I just am not gonna understand your POV on this. I can’t fathom why not just let a PC be part of a crew that did the incredible but very possible feat of crossing beyond the known world without dying. I mean, it happened IRL, in various centuries and places. Why should it only be an option if the PC wants to play out that journey?
It's quite possible that a foreign character is not a good fit for the campaign and the DM doesn't want to shoehorn it in. That's a completely legitimate reason to say no to the concept.
