Shapeshifters

Characteristics
Shifters can look entirely human. People can do spells to locate them but based on appearance alone they would be nearly impossible to tell apart from everyone else.

Special Abilities and Distinguishing Features
They can turn into animals. In Ascension some have mastered the ability to turn into different races. Most shifters choose an animal for water air and land, though they can change into other things as well. How a person shifts really depends on their personality. Some don't have as much control as others and can shift at random times.

Cultural Description
The shifters are spread out and in various place so there's no exact society.

The world as a whole treats shifters like criminals so most live in secret or in places where they aren't under a microscope like the Porters on the sea or Remy with the Hunters.
