Dragonsword Mountains
Also called the Sword Mountains, this chain of high, allegedly impassable mountains (no one in Mulhorand climbs mountains "because they're there" has never occurred to them) separates Mulhorand from the Plains of Purple Dust; when the wind is very active on the Plains, it blows red dust over the mountaintops and onto the western slopes. Within these mountains are a number of fierce monsters that plague southern Mulhorand, most notably Gestaniius, a great wyrm blue dragon that has fed on the slaves working in the Land of the Dead for well over 600 years, the descendants of the wizard Nezram, and dracosphinxes.
On the edge of the Sword Mountains, in the Great Vale, are some of the tombs of the dead god-kings. The greatest tomb, that of Horuseres II, was carved out of the very mountainside and is said to lead into a treacherous series of natural caverns where the pharaoh and his riches were entombed. None have ever sacked his tomb, but several minions of Horus-Re guard it at all times.
