The Singing Bone

Origin
The Singing Bone tells the story of two brothers who went on a hunting trip. The younger brother was successful with the help of a dwarf and returned home to find his less noble brother drunken. After getting the younger to speak of the adventure, the older brother kills the younger, buries his body, takes the fabulous boar to the king and marries his daughter. However, a shepherded notices a bone sticking out from the ground and fashions it into a mouthpiece. It begins singing by itself, and when presented to the king, recounts the tale of the murder. The older brother is executed, while the younger is relocated to a beautiful graveyard.

Effects
When blown into, the bone produces lyrics heard in the head of people in the vicinity, including the user, telling of wrongdoings committed by the listeners, and compels others to punish them accordingly. Everyone hears the same lyrics, not only their misdeeds in their own head. It moves from the biggest crime to the smallest that pertain to the listeners until complete, after which it will fall into silence. The larger the groups of people or more irreversible the deeds discovered, the quicker the wielder’s body flesh will calcify into bone substrate.
