Shapeshifting

The ability to transform into an animal of some kind. The shapeshift will always be from human form to some sort of animal. The animal can optionally look different than expected, such as a white crow or black fox. While in the animal form, the magical person can speak normally and others can understand them. The magical person retains all of their normal intellect. Also while in the animal form, the magical person has a unique ability that otherwise does not come naturally to the animal. For example, if the person can transform into a bird, flying would be a natural talent and thus not considered magical. However if the bird can read minds, that would count as it’s “unnatural power.”

Every seven will have some form of this as their 7th and final ability. Shapeshifting is not exclusive to sevens, any magical person can have this as a power, even a lowly one. The caster cannot transform into multiple kinds of animals, just a single kind that suits them.
