Mystics are intelligent, often magical creatures that blur the line between Sentient and Bestial. Mystics often wear clothes, perform religion-like rituals, and some can even speak International.
Though they can be intelligent, they are very mysterious and they choose not to interact with Sentients and survive in their own cut-off cultures. Not all Mystics are believed to exist, and those that are confirmed to exist mostly separate themselves from Sentients by choice.
Whether or not Mystics are considered animals is a very debatable topic. There are many arguments about whether it is considered wrong to kill Mystics as if they were animals, and many Sentient kingdoms have banned their hunting and consider it a form of murder.
Some countries, such as Canis La’Can, give Mystics civilian rights and consider them the same as Sentients.
