The Mountains of Morderant are a mountain range in Zarhanna, on the world of Lezaria. They comprise the border between Thalarey and Taverak.

The city of Razelten lies along the coast at the southern edge of the mountain range. Azar is situated in a valley near the Pass of Sharmen, on the main trade route between Thalarey and Taverak. At the north end of the mountains lies the city-fortress of Tinemocun, the seat of the Lezarian Council.
