The Dead World, also known as the Pendent World, is the moon of Pellucidar. It hovers roughly a mile above (below?) the surface of Pellucidar. It rotates at the same rate as the earth. The moon contains mountains, oceans, lakes, rivers, grassy plains, and dense forests. It is called the dead world because the Mezops lay their dead to rest in trees so that birds may find them and carry them off to this moon. It casts a shadow over the land, create a place known as the land of awful shadow.
