Polymorphidae

Polymorphidae are what we commonly call shape-shifters. They are beings that have more than one definitive form and can move between them fluidly. We are familiar with the notion of shifters from human folklore and literature, but polymorphidae often don’t fit with the image we gave them. For example, many assume that polymorphidae have one ‘true-form’ from which they shift, but that is not the case. All the forms a polymorphidae magion can take are natural to them. They may have a preference to one, but that is a personal choice that is not rooted in their species. The magions in this group were born with the ability to change form, and this ability is usually innate since birth. Furthermore, the change affects their form only and, while senses or abilities might change with the physical appearance, their mind remains the same in all forms.
There is an additional classification system for shape-shifters, based on the character of their shifting. This system includes three categories: physical shifters, arcane shifters and curse shifters. Polymorphidae magions consist of the first two categories.

It is important to note that the polymorphidae group does not include creatures that have been cursed or otherwise caused to change their form. Nor does it include creatures that learned to change their form with magic.
