The Vashta Nerada are killing shadows. They take over people's body's. How you know there's a Vashta Nerada is in someone's body is if they look like a skeleton or if they have two shadows. If you go into a Vashta Nerada you die instantly. The Vashta Nerada live in forests and were in a library. Why they were there because the books are the trees. Will Donna Noble died and turned into Humpty Dumpty. Bye.
