Anne Boleyn's Pearl Necklace and Ornate B

Origin
Anne Boleyn (1501 - 1536) was Queen of England from 153 to 1536 as the second wife of King Henry VIII and Marquees of Pembroke in her own right. Her marriage to the king and her subsequent execution by beheading made her a key figure in the political and religious upheaval that was the start of the English Reformation. When she became Queen in 1533 she also gave birth to the future Queen Elizabeth I, however she was unable to produce a suitable male heir to the throne and Henry had her investigated for high treason. During the investigation Boleyn made it hard for her husband's men to locate her as she was always moving around the castle. Boleyn was eventually arrested and sent to the tower of London, she was found guilty and was beheaded four days later.

Effects
Teleportation, when wearing and thinking about the location. Without the B there's a chance the necklace will teleport wearer to an English field and will stop working until the two parts are whole
