Aurora

One of Princesses of Heart. Her appearance is taken directly from Walt Disney's "Sleeping Beauty" (1959). Although her original voice actress, Mary Costa, was alive at the time of Kingdom Hearts' development (and is still alive today), Aurora spoke in dialogue boxes for her appearance.

Kingdom Hearts
Aurora originally resided in an as-of-now unnamed world in the Kingdom Hearts universe, presumably based on King Stephen's Kingdom in Disney's "Sleeping Beauty". At infancy, Maleficent laid a curse on her, proclaiming that, on her sixteenth birthday, Aurora would prick her finger on the spindle of a spinning wheel and die. Thanks to the aid of the three good fairies (Flora, Fauna and Merryweather), Aurora's curse was softened by the addition that true love's kiss would wake her from her sleep. To keep her safe, she was renamed Briar Rose and relocated to the forest of her world with the three fairies caring for her. On a chance meeting, Aurora encountered Prince Phillip, who she was betrothed to (unbeknownst to her). It is unknown at what point of the original story Aurora was taken to Hollow Bastion by Maleficent, but the crown on her head suggests that it was directly before Maleficent lured her into pricking her finger on the spinning wheel.

Aurora's likeness first appeared in Kingdom Hearts on a red-tinted pillar in the Awakening world. She was depicted in a state of sleep, suggesting that she had already been captured and imprisoned by Maleficent at this point.

She was first seen in Hollow Bastion when Maleficent attempted to open the Final Keyhole. Maleficent had placed Aurora in a standing glass case in the wall, alongside the other Princesses of Heart. Her heart left her when the keyhole was opened, but was returned to her when Sora sacraficed his own heart to save her and the other Princesses. Upon awaking, Aurora stayed in Hollow Bastion to stop the darkness from consuming the world. She also revealed Maleficent's origins to Sora. When Sora finally sealed Kingdom Hearts, Aurora was returned to her world.

Kingdom Hearts II
Although Aurora did not make an appearance in Kingdom Hearts II, her name was found to be part of the password to access the DTD in Tron's world.

Trivia
Rumors are currently circulating that Aurora's world was spotted in the Kingdom Hearts: Birth by Sleep trailer at the 2007 Tokyo Game Show, leading to the speculation that she will make a return to the series with the premiere of her world in the Kingdom Hearts series.
