[Archonsod]

Given the prominent role the Deer also plays in Turkish mythology it might also make a good summonable as some kind of cavalry (or possibly a national teleport spell, IIRC the Deer was often given the role of a guide).

A divine mountain of some description would probably be the most apt special site.

Magic wise you could borrow slightly from Arabic legend and have the land ruled by Sultans and Caliphs who make use of both wealth and magic to keep their positions, certainly in the late age.

Mind you, you could always mod the nation in yourself if you feel like making the effort.
