The Red Cliffs protects the southern borders of the human lands of the South Marches from the Southlands that lie beyond it as well as the Volcano in the south and the Great Green Sea further to the south.

The Red Cliffs get their name from the red limestone, sometimes called 'Bloodstone ', that makes up much of the cliffs. The cliffs vary in height from the ground level but can rise as high as sixty feet in some locations (mostly towards the mountain borders on both sides) and as low as thirty feet near The Crag

The Red Cliffs are capped by the infamous 'Red Wall' that lines its edge to provide an additional barrier towards the Orc, and Goblinoid hordes in the south.
