Mount Evermourn, along with the mountains of the Mithral, the Sentinels and the Griffin's Marl, is one of the highest mountains in the Santharian province of Manthria. It is located at the east coast, between the two largest cities of the province, Marcogg and Ciosa, and its highest peak, the Kilmaen, is supposed to reach more than 4.000 peds in height. Mount Evermourn is said to stand guard to the Deep Julin Barrows (Ciosa's Rest), where among many others the legendary Glandorian and first Avennorian settler Troi Ciosa, was buried, thus the mountain received its name.

Mount Evermourn however is more than that: Though most of the crystals in the mountain have already been mined, you can still find many interconnected stalactite caves and a gigantic underground sea, Lake Glandolan, in Mount Evermourn, with an isle of stone on it. There the ancient Avennorians erected the sparkling self-illuminating underground citadel Ciosastran out of the most valuable materials available and they built magnificent golden bridges to reach the isle from all sides. At Ciosastran the leaders of the Avennorians met to discuss important matters, and during the time of the Vardưnnian atonement the stalactite caves even became home to many people who believed that remaining in the eternal night outside would be there doom.

Since then Ciosastran is more than just an official meeting place, but has developed to a location for people who seek the different. In the expanded Ciosastran citadel you will now find alchemists, spell shops for Xeuátans, some of the most famous smiths and mapmakers, who can endow you with cartographic details from all parts of the known world.
