The magic dust is a magical substance located in a deep cavern in Wonderland. The Red Queen sends Alice on a dangerous mission to retrieve it for her, so that she may save Will from his stone form. Later, Alice uses some of the dust that she stole to lead the way Cyrus.
After the Curse
Will is saved by his former lover. ("Heart of Stone")
The Red Queen goes to the edge of a cliff and extends one foot over the edge. After a moment she pulls her foot back. Later, while Alice tries to comfort the stone form of Will, she's approached by the Queen, who offers her a deal; if she retrieve some magical dust that will help protect her against Jafar, then she will help her locate Cyrus. After much reluctance, Alice agrees. When they reach their destination, they find that the gap they must cross is too long, however, Alice is shown a riddle which states a person pure of heart can succeed. Believing her love with Cyrus is pure, she attempts to cross the gap. At first it works and Alice magically walks through the air, however, this suddenly comes to an end and she falls down into the pit beneath her. She is confronted with a vision of her child self, who uses its power to knock the Red Queen down into the pit with them and then the tries to persuade Alice into killing the defenseless queen. Alice tells a begging queen that she must pay for her crimes and then swings her sword at her, however, she misses on purpose, stating she won't be the one to make her. Alice's child vision suddenly becomes innocent and clean looking, stating she passed the test. When both Alice's touch hands, the child version dissipates into dust...the dust the Red Queen wanted. Alice collects it up and once they escape the pit, the Red Queen betrays Alice and takes the dust without revealing Cyrus' location. When Alice says that she gave her her life, the Queen insists that everything she had, she had to take. Alice asks about what she's lost, and the Queen warns her to take care as she walks away. Then, the Queen goes to the Knave's statue and strokes its face. She says that she's sorry and then sprinkles the magic dust on him. The Knave is restored and she quickly walks away before he can see her. ("Heart of Stone")
