Crystal Aurora Overland

Crystal Aurora Overland is the guardian of Adventure. She was chosen by Man in the Moon about 50 years after Jack Frost was chosen to be a guardian. She is the sister of Jack Frost, but neither of them knew until Crystal saw her memories.

History
Crystal was resurrected by Man in the Moon about five years after Jack saved her. Like Jack, she had no memory of her past. She was in the forest next to the town of Burgess. She decided to explore and found the town, only to realise that she was invisible. Crystal ran back into the woods, terrified and confused. A lone wolf named Shadow saw Crystal, knowing that she is the one Manny had sent him to find. Shadow helped her discover her powers after giving her an ancient amulet called the Sapphire of the Aurora Borealis. He taught her about nature and wildlife and how to respect them, since animals were the only ones that could see her. Crystal learned everything she knew from the forest animals. The birds taught her how to use her wings, the wolves and the bears taught her how to build a shelter, and Shadow continued to teach her how to use the amulet to turn into and use the abilities of every animal. But, the animals also taught her to stay away from the town and humans. Crystal and Shadow stayed in the town of Burgess until Shadow decided that they should move to Yosemite National Park. He noticed that the town was growing and people had started to clear the forest. Yosemite was protected from this and would be a safer place for Crystal to practice her new powers.

Powers and Abilities
Crystal has the power to turn into almost every animal in the world, even mythical creatures. She can also use the abilities of every animal that she can turn into.

Crystal also has a new power that she has discovered after a battle against Pitch. She can shoot a beam of the northern lights from the Sapphire Amulet and her wings. When this combines with Jack's winter magic, it can cause an explosion of light and frost.
