Wraith Amulet

The medallion is a mysterious item that, when a person either picks up or has direct skin contact with it, can instantly mark a person for death. Once the person is branded with the medallion's symbol, a creature called the Wraith will hunt and stalk its' prey until it has successfully sucked out the person's soul.

History
After Prince Phillip and his companion, Mulan arrive in the remains of a palace, and he is able to use the true love's kiss to awaken Princess Aurora, a Wraith appears and attacks the group. Prince Phillip grabs a hold of the medallion around the creature's neck. Because he touched it, he gets marked with the medallion's symbol, and becomes the Wraith's next target.

At the same time, in Storybrooke, Mr. Gold seems to have the same medallion. Mr. Gold seeks vengeance against Regina for having locked Belle up for 28 years and keeping it a secret from him. He pays a visit to Regina in jail and forces her hand against the medallion. Then he summons the Wraith and orders it to kill Regina. However, Belle is quite unhappy he is using means to harm her.

Prince Phillip, Princess Aurora and Mulan travel away into the Enchanted Forest. As the sun is going down, they decide to stop and set up camp for the night. Aurora is noticing Phillip might be hiding something from her, but he won't say what it is. They share a kiss, and he goes off to look for wood promising to return in five minutes. When his back is to Aurora, he has a troubled look on his face.

Later, after Phillip has not returned for some time, Mulan realizes Phillip was marked by the Wraith, and she rushes off on horseback after him while Aurora hastily follows behind. They find him, however, none of them are a match for the Wraith. Mulan suggests she be given the medallion so she can mark herself and die in his place; thus saving Phillip from the fate of death. He refuses, and allows the Wraith to suck out his soul while Aurora and Mulan look on in horror. His last words are, "I love you". After taking Phillip's soul, the Wraith goes back into the medallion.

The Wraith after Regina was nearly successful in taking her life, but it is interrupted by Emma, Mary Margaret, and David. They found out from Mr. Gold what he had planned for Regina. Emma decides to protect Regina because Henry would not wish for anything bad to happen to his adoptive mother. One of the Wraith's weaknesses is towards fire, but they are not able to kill the creature. Regina throws out the suggestion they send the Wraith to another place in time so it can't harm anyone ever again.

They manage to lure it to Storybrooke Town Hall and Regina uses Jefferson's hat to open a portal. The Wraith is eventually pulled in, but accidentally, Emma is also drawn in. Mary Margaret refuses to watch Emma disappear before her eyes again, so she jumps in, too. The portal closes just as David tries to follow them.

Princess Aurora and Mulan journey back to the remains of the castle. They lay Phillip on the same pedestal Aurora herself slept on for 28 years. The medallion is then wrapped in a bag and given to Aurora by Mulan. They prepare to leave for safer grounds, but a noise causes them to stop and investigate. Mulan turns over some rumble, and sees the unconscious bodies of Emma and Mary Margaret. She sees them as the reason for the Wraith's appearance, and Phillip's death. ("Broken")
