‘passage to the desert’ (Svt) Castle in southern Eldara, also known as the Gateway Keep. This powerful fortress guards the main entrance along the Kerak where it intersects the southern trade road to Il’Vak. The castle was built into the great barrier wall and is the largest battlement on its entire 320-mile length. Completed in the Fifth Age by the Ravinian Empire, the castle was the pride of the Kerak and its strongest point. The castle is still a near-impregnable fortress and one of the largest fortifications on Corwyn. At one time the large castle had an Imperial garrison of 5,000 troops, but now musters only 1,000 soldiers of Eldara’s army.
