Nice but I would suggest that a highly arid krast highland in the Kazuh Mountains with a single mountain pass leading out of it to a small west-facing coast or a area of desert coast split from Lamea by Kazuh Mountains, both somewhere alongside the west coast of Lemea, would be much better as a location for you country since otherwise the sturdy Orcs would braved trough any desert while settling in Lemea, only a great natural obstacle in which even they can't move and live without extreme troubles like the Kazuh Mountains would stop their advancement.
