Balan's Gap

From Girl Genius

Balan's Gap is the pass on which the town of Sturmhalten is situated. It is apparently one of the only passes open in the early spring, and thus a major way-point. (One might suspect it's a pass through the Carpathians, but there are no good clues.)

Master Payne's Circus of Adventure had to take the road through Balan's Gap on their way to Mechanicsburg because their preferred route — through Passholdt — was overrun with monsters and the bridge to the town was destroyed.
