The Pantari are a homebrew race
They are the same size as thundercats, but they are nothing like them. Whereas most races of our world are peaceful(mainly) and try to maintain homeostasis, the Pantari have a taste for war. They are extremely skilled at warring activities and therefore most people have branded them as evil for their abilities to hurt other peoples. Reefa was born out of need to keep the warring from the peaceful, and consequently the evil peoples of our world like to stay in this area, because they are nowhere near as prosecuted as they are in other places.
