This charm was rewarded to Adrasteia for passing Aphrodite's test, carried out by Neleous. Adrasteia was informed that their destined other, had also succeeded this test and was out there for them to find. However now the charm has been taken from Adrasteia when she was captured by the Owl and Spear. Adrasteia has since had it returned to her by Thogarth on the command of Aphrodite in Imperum before journeying to the Ashen Wastes. They have since found the matching charm, when they were brought to Ogygia and met Calypso.
One has also been awarded to Ghost by Thogarth much to their chagrin as they beleived Ami to be their soulmate.
There have ony been two other appearances of this charm, a broken one was carried by the archaeologist Eingwyn. Who allowed herself to become corrupted at the chance of resurrecting and finally getting to meet her soulmate who had died.
