[That response triggers laughter from Keldor. Not at Radley's expense, no, but at himself. He's only known Radley a short time, but already regards him as a trusted friend, and as such had briefly forgotten that Radley doesn't know Eternian customs.]

No. No. In Eternia one does not say things like "goodbye" as is the custom here. One says "good journey" instead.

[Now, with it explained properly, so Radley understands the context,]

Good journey, friend.
