Cardas Gap is a narrow, open plain in Keledon. When the Ironfist Mountains break into the rolling foothills of South Avendur, they eventually open up into a narrow valley, which in turn gives rise to an open plain between Dogswood Motte and Sturmond Tower.The land in the Gap is rocky, acidic, and less fertile than some of the surrounding regions, but it is well-watered. Pastoral pursuits are more common in the Gap than agricultural ones. The people of the region are dour, stern and untrusting of outsiders, especially Akarthans.
A great deal of the Gap is visible from the hilltop fortress of Cardas Eye.
The region is ruled as part of South Avendur by the Keledoni House Dreigon.
