Spine, The — a mountain range that runs from south of the Darkwood Forest to the northern edge of The Forbidden Zone. It also represents the eastern edge of the Middenmark region. The mountains in the center of The Spine are ice-capped. The range is known to be rich in minerals and gemstones. The dwarves of Citadel Silver (Silverhame) mine iron ore, silver, and gold. Bards still sing songs about the first dwarves and how they built a great kingdom in the mountains. Waves of monstrous humanoids, orcs, goblins, trolls, and giants from the far north, pushed them out and they fled to the southern tip of The Spine. Some say the dwarves even found a single vein of Mithril, the most rare and precious of metals, running through the mountains.
