Delicate Music Box

Source
Delicate Music Box is a common night elf archaeology artifact that requires 35 fragments, and permits use of one keystone.

Description
This box is of sandalwood with a tiny clockwork elf and nightsaber within. Although the winding mechanism is no longer functional, you can imagine the two would dance together while music played. Engraved on the bottom: 'To my dearest Theleste.'
