OK, @WinterHawk and everyone: here’s a new hand-drawn map of the gameworld, in which Karagon is shown as the landlocked backwater that it is.
For reference, this world’s Arctic Circle passes just north of Yanzir, and Shayard City is a little above the 30th parallel. The map has Mercator-esque distortions as you go north, so Nyryal is actually quite a bit smaller relative to Shayard than it appears here, and Erezza’s not quite as big either.
