Soul ravines in the nether

The soul ravines can sometimes be found on the edge of a soulsand valley. It is very deep. If you stand at the top of such a ravine you cannot see the bottom because of the blue fog. If you go down through the fog you don't really see much more. The only thing you can see now are many glowing balls that float through the bottom of the ravine. They make scary soul sounds. These are souls. You cannot kill them. If you trie hit them, they simply poof to another place. You can also see strange holes in the walls and floor here. If you go there you will come across a whole corridor system. In that corridor system you will find many gigantic fossils and bones (made from bone blocks) that still have some meat (made from a new meat block) on it in all kinds of places. A dragon lives in this corridor system. Not as big as an ender dragon but still dangerous. The dragon is made of bones and spits blue fire. If you stand at the top of the ravine you can sometimes hear the roar of this monster from the bottom of the ravine. As soon as the dragon realizes that you are present in the ravine it will come to you and tries kill you. The ravine is made of soul stone and small groups of soulsand.
