 SCP-573 is a flute made from bone. DNA and carbon testing reveal the material to be human, female, and approximately a thousand years old. The bone is a femur and, from the size, comes from a child between the ages of 7 and 12. SCP-573 was discovered in Louisiana by agents investigating the disappearance of local children. Agents arriving on the scene were attacked by a pack of wild animals. Once the animals were put down, the agents were then attacked by several of the missing children, being urged on by one derailed king, the then owner of SCP-573.
