These are Ink and Flarestep (Oddly, Ink is the orange one and Flarestep is the black one) Story Ink was corrupted by a Shadow (Creatures that try to gain more power by corrupting cats) When Ink was too emotional, the Shadow tried to take control (The black paws, the wings, the randomly turning darker) Once, she lost control and killed her best friend, Flarestep. When she realized what she had done, she almost gave in to the Shadow. The spirit of Flarestep appeared, and tried to convince her that it wasn't her fault.
