@matthew_loftus I was told once that it’s in case some kind of emergency happens while you are in that country and you are, perhaps for a medical reason, unable to travel. Got that from a student travel company once, for what it’s worth.
In The Hobbit, neither Bilbo nor the dwarves kill the dragon. In The Lord of the Rings, Frodo doesn’t destroy the Ring.
It is often the case that our task is simply to play our part in a larger story.
