The impregnable, mountain-top fortress of Athos-Sorel, which means "passage to safety," serves as the royal citadel of the Kingdom of Ammarind.

Athos-Sorel is located in the center of the kingdom on a large mountain overlooking the plains. The fortress is so high up, that from its great towers, one can see many miles east to the banks of the Athlan Myr, or west to the eastern peaks of the Axehead Mountains.

In the Great Hall of the castle is the legendary Brass Throne. This mountain fortress was built in the year 0015 of the Fourth Age, and became the citadel of King Edric Garigan; the man who founded the Kingdom of Amar. Since that time, this vast, lofty fortress has been royal citadel of both Amar and, later, Ammarind.

Over the last 3,159 years, the fortress has been home to 119 different Amari monarchs and their families:

Throughout its history, the castle has been besieged seven times but has never fallen to any foe; to the undying pride of its people. The castle was besieged for over a year in 1275/4, for over a year in 432/5, again from 521-524/5, and again in 548/5. The fortress weathered nearly four years of siege between 621-625/5 during the War of the Cataclysm. Later, Sorimmar’s armies again laid a five-year siege during the War of Crows. Most recently, the fortress for six months in 1167/6, during the Border War. None of these seven assaults ever succeeded.
