Arderine Pass
Arderine Pass is a narrow mountain pass linking Fabul and Damcyan. Although there are smaller footpaths around Mt. Hobs, Arderine is the only place moving an army through the mountains is feasible. Not surprisingly, it's been the site of many important battles. In the Great War the Grand Army suffered massive losses as they moved through; only their superior firepower allowed them to transit the pass. The much less competent Damcyanese army was routed when trying to move through the pass during the Leviathan War.
