Swifts:
These little things are weirdly slender and run like the wind, though not a blur. They take on any form or shape in the animal and human shifts. They have natural ability to let there soul leave there body and zoom past them, very handy in fights. Unfortunately, they tend to have the most defects since they were the last shifter ever made by the keepers. Examples would be blindness, a second limb or horns, death at birth, ect. If you want to fight a swift, be careful! For they can turn invisible whenbthey want! Even though this comes naturally to swifts, it takes many years to master this ability, some can't even sumon this skill.
