Cressevain Peaks
The Cressevain Peaks are the tallest peaks in all of the Archipelago of Bennoria. They are located on the island of Inai in the north eastern part. The mountain range separates the plainlands from the swamp. It is full of rare ores and minerals and is home to several dwarven strongholds as well as a few mining operations. One of the specialties of the Cressevain Peaks is the black marble it has, Cressevain Marble, that is widely sought after by the wealthy. For thousands of years it was thought to be impossible to cross the mountains to reach the swamps. In 115 A.S. the explorer Nori Glorgul found a small, hard to navigate pass to get from one side to the other. If any had done so before her, there is no record of it.
Short and simple, gets all the information across :D
