Trait: Changeling
A creature with this trait is a member of the Changeling ancestry. Changelings are, often, the offspring of a Shapechanging progenitor, or are shapechangers themselves who've developed a preference for humanoid life and society. Their true forms vary widely, as do their origins, as some may be Fey in nature (related to the Doppelganger, for instance), while others may have origins stemming from magical experimentation, or supernatural magic. An ability with this trait can be used or selected only by Changelings.
