Dragon Pass is probably the most important place in Glorantha, sitting at the crossroads of the continent of Genertela. The actual Dragon Pass is a narrow valley near Mount Kero Fin that crosses the continental divide, but over the centuries the name has come to be applied to the whole 140-mile gap in the Rockwood Mountains and to the region around this gap. The Dragon Pass region is large, perhaps 40,000 square miles in total area, even bigger if its boundaries are determined liberally.
Dragon Pass is one of the most militarily significant regions in Genertela. It offers the only passage suitable for large, heavily encumbered armies through the Rockwood Mountains, which extend unbroken for roughly a thousand miles to the west and about 625 miles to the northeast. The region contains much easily defended terrain, such as forests, hills, and mountains. Most importantly, its warlike population and many magical entities make it a daunting region for any army to pacify or conquer. For more than a century, two Orlanthi kingdoms have divided Dragon Pass: Tarsh in the north and Sartar in the south.
Much of Dragon Pass is hills and mountains, but its many valleys are fertile and rich. The area is well-watered, warm in summer and cold in winter. Most of Dragon Pass is over 2,000 feet above sea level, and notorious for its destructive storms and violent winds. Mixed forests and rough grasslands cover most valleys and foothills, except where people have cleared them for farming.
To the south of Dragon Pass lies a magical land called the Holy Country. To the north of Dragon Pass is Peloria, dominated by the Lunar Empire. To the east of Dragon Pass are the plains of Prax, an arid chaparral land inhabited by the Praxian Animal Nomads.
