During the era of Bredden’s Expansion, King Bredden sought to expand the dwarven lands to the south and west. In order to do this, he set his sights on the Dragon’s Spine mountain range as a main avenue of expansion into the south. The Dragon’s Road was one of the largest undertakings in Dwarven history. The war with the Scaled Ones drew the Dwarven forces south out of The Thunder Hills and Mount Thunderhead to do battle along the bank of the Wunder River in the foothills of the Dragon’s Spine. Bredden used the fighting to bring brigades of workers and craftsmen into the mountains to begin their decades of work.
The first project completed was The Dragon’s Road, a wide tunnel that ran the length of the Dragon’s Spine, with strategically placed openings sheltered by surrounding peaks to allow air flow into the road. Several fortifications and stockpiles were built in the mountains before the expansion was abandoned by Bredden’s successor King Karoda. To this day, these fortifications sit unused in the mountains, abandoned for centuries but still readily usable due to their strong Dwarven Construction. Some of the fortifications that persist along the Dragon’s Road include the Deep Well, Mother’s Peak, the Opal Fort, Durgbor Castle, Jotun’s Steppes, and the pride of the expansion’s efforts, and what was to be the seat of power in the Dragon’s Spine, Lightning Valley.
