Vashta Nerada

Today I would like to talk about a quite scary creature. It scares children and even adults. It hides in the hidden shadows, in the mist on midnight, and controls the un-dead. Can you guess what I am, perhaps the Vashta Nerada! Comment and tell me what you think of this horrifying creature! I would love to hear what you think! Also, help me spell it's name! Who has a better spelling, Really?!?!?
