Dreaded object of my brother's schemes. Perhaps there is another note to send her back? If so, let that be the one I play. 
History
The Lur of Luramena was stolen by Thor from his father, Odin's, vault at the urging of his brother, Loki. After returning to Loki, Loki sounded the horn, summoning Mildred.[1] During her rampage, Thor blew the horn again, summoning Mildred's mother. She berated her daughter and carried her home. Odin presumably took back the Lur when he confronted his sons.[2]
