==Known information==
This shining amulet bears a blue to green colour. When worn it can be used as a spellcasting focus by Bards. When used in this way, the amulet will create a spectral instrument that the wearer is proficient with. 
It belonged to a Goliath who was known as the Rustling Branch for her calming music. Instead of simply a performer, she also used this weapon in combat to great extent. It slowed or hastened those around her to change the outcome of many battles. She distanced herself at some point and has been missing ever since.
