The Spine is a hostile mountain range that splits the continent of Argentus in half like a belt. The Spine is interrupted only by a strange and dangerous valley called the Plain of Fear. The Spine is riddled with caves, swarming with dangerous creatures, and plagued by sudden snowstorms.
The mountains west of the Plain of Fear are characterized by the massive clan of Duergar called the Ul’vol. The mountains to the east host the Drow empire of Dar-davir. These kingdoms are constantly at war, above ground and in the caves below.
Besides these, dwarves, gnomes, goblins, orcs, griffins, and many other creatures call the Spine home.
The many intense dangers of the Spine make crossing through it nearly suicidal and rarely done. Travelers who wish to reach Orestead from the north or vice versa must go around, by sea.
