It is just absurd how even in Act I we see how people died trying to deliver some letters. Why didn't he travel by portal?
How can you know if he didnt ... maybe he traveled to closest known portal, but rest he needed to take on foot.
I like the idea with signposts and message - "You traveled for 1 hour".
You cant "travel for 1 hour" in game that have no time ... it simply dont make sence that you spend 1 hour "fast traveling" but no time traveling "usual way"
