The Imiriaran Cycle
Fortress is the largest and most formidable fortification in its region of the Imiriaran continent. Headquarters to the Valerian branch of The Sword of God, this castls houses more than 20,000 Sword at any given time. Built in five concentric rings with five sections each, the walls form 25 separate baileys, each housing barracks for 1,000 soldiers. The walls themselves are sectioned by large gates mounted on top, so that an invader taking a single bailey, while he can then achieve the walls themselves, must take these gatehouses or an adjacent bailey to conquer another section of the castle. Single baileys have fallen in the past, only to have the defenders find that gaining the battlements only exposed them to fire from the upper gatehouses. Fortress has never fallen. It’s never lost more than five baileys. It’s said that as long as Fortress stands, Valesh Eren will survive.
