The southern portion of the Nightmare Lands on the planet Voss was known as the Deepest Woods. This area was situated between the Twisted Forest in the northern part and the untouched Sha-Thes Meadow to its southern edge, past the region's black stone boundaries. Within its steep ravines lay several caves, one of which was the Cave of Reflection. Additionally, the Char-An Commando Outpost, the only secure base located within the Nightmare Lands, could be found there.
The Deepest Woods is featured as a location on Voss in the video game Star Wars: The Old Republic, released in 2011.
