I was wrong Torm. It was Riatavin near the Shilmista forest and Snow Lake mountains, not Iriaebor. The country I was thinking of (like a few left off of the FRCS map) was Erlkazar. It was originally Scottish highlands in flavor, but that was before Tethyr was changed.
Erlkazar is just east of Tethyr and Amn. Amn being more like medieval Spain and Tethyr now more moorish Spain than Scottish. Erlkazar could be taken now as the Andorrans in the Pyrenees (southern france). Oddly, there really are very few French-like countries in most campaign settings.
