Teirm is a large trading city in Alagaësia. It is a coastal port isolated from the rest of the Empire by the Spine, and is located on the Toark River. It has a defense system like no other city in Alagaësia: after an attack by pirates in which the city nearly burned down, it was rebuilt in a tiered structure so that in case of attack, archers could be posted on the roofs of the houses they would have a clear line of sight to shoot down the invaders. The defenses were centered around a citadel, in which the merchants were required to house their administrative offices so that Imperial officials could track shipments to the Varden.
