Cripple Peak is a mountain peak at the shores of the Sour Sea. To the east lie the Broken Teeth and the Plain of Bones, to the west the Sour Sea, to the north and south the Worlds Edge Mountains. The desert land of the Desolation of Nagash surrounds it.
The mountain was split in two during the first Chaos Incursion by a chunk of warpstone that bore itself through the peak and deep into the earth below. Later the mountain was excavated and sculpted so that it became the fortress city Nagashizzar, the Cursed Pit, home of Nagash, the Great Necromancer.
