The beast appears to have originated in the Feywild.[2] In the Feywild they were trained by the Unseelie court for hunting purposes. Eventually the Displacer beasts broke free of the fey's control and roamed causing chaos wherever they went. After the left captivity Unseelie court sent out blink dogs to track and drive the Displacer beasts out of the Feywild and into the materiel plane.[1]
Displacer beasts were large cat-like creatures,sometimes described as panther or puma-like with six legs and a pair of long tentacles sprouting from their shoulders. They were covered in a pelt of blue-black fur. They were usually about 9 feet long and weighed as much as 500 pounds, but the occasional mutant could be twice this size. In some versions they were considered to be emaciated.[3]
These monsters lived in small groups or preferred to be alone.[3] Many humanoids trained them to act as guards or pets, such as evilfey(Unseelie court) and oni.[2]
