As you leap into the air, you lose your grasp on the wand and it drops to the floor. As you watch the wand tumble to the ground, you forget to focus on flying or landing, leading you to end up in a disorganized heap of clothing.
Pulling yourself to your feet, you smooth your dress back down and rub your head, peering around on the floor for your lost tiara and wand. The wand landed in a corner of the room and seemed to be sparking. You tentatively reached for it, but briskly pulled your hand back as the sparks began to fly more furiously.
All at once, the star at the top of the wand shattered in a mini explosion. To your surprise, what remained after the wand broke was a small cloud of darkness.

The dress seemed to stop there, no longer progressing to cover your shoulders or arms.
Finally, the mist surrounded your neck, forming a lacy, black collar with a black bow fastening it together. The mist finally begins to pool into the middle, creating a necklace that ends in a large ruby. The mist seems to pour into the gem before disappearing.
Just as soon as your transformation ended, you feel your mind becoming assaulted by new thoughts. You cry out as you try to resist them, but one word usurps your control and demands your attention.
