Used material(s): Cast in antique silver-plated pewter key
One of: Unlimited
First appearance: Keys to the Kingdom #1
Use: Allows transformation to animal form
Door: Animal Door
The Animal Key was discovered by Bode Locke in a frozen fountain though it was originally hidden in the Hunting Trophy’s Room. He used it to turn into a sparrow, and Dodge used to to turn into a wolf. Bode eventually used it to regain his human form.
The key opens a door on the outside of the house. When a person climbs through the door, they are transformed into an animal and can communicate with other animals of the same species. It is unclear whether there is a way to choose what animal species you become, or if it is somehow a reflection on the person.

He gave me a short, lordly look, and took to the skies…”
