Geb-el-Mardikh Mountains

>Geb-el-Mardikh Mountains This mountain range runs north and south along the Ruby Sea, along the east coast of Upper Khemit and on through the Nubiar Oversight. (See “Nubiar Oversight” below for more information on that area.) It has almost no passes through it, and none large enough for a caravan to travel, so the coastal villages to the east have contact with the rest of Khemit only by water. The mountains are full of caves and are said to be populated by many underground species, including dwarves who never come to the surface, and kobolds. Any deep dwellers very rarely venture out of the caves, although sometimes an isolated coastal village is found destroyed with no sign of the attackers. The range also has many dangerous creatures aboveground, of course.
The mountains have some valuable mineral resources, but the distant location makes them troublesome to mine. Silver, marble, and garnet are available, among other things. Gold and silver are found together in some rock; rather than trying to divide the two (a complicated task), the metals are simply combined into electrum and used that way, so electrum is more common in Khemit than most areas.
