Interplanar Dragon
Dragons from some unknown plane who have gained the ability to travel through worlds with ease. They are great hunters and assassins, and willingly sell their services for treasure. It is said that they keep their hoard in a pocket dimension somewhere, hidden from the rest of creation. Some say that the Interplanar dragons serve some higher, unnamed power, but if that is so its agenda is thus far unknown. Interplanar dragons are fond of grappling their prey, then using their Plane Shift ability to remove it from the group, possibly bringing it to a more secluded plane to eat it, or bringing it to a more dangerous world, or possibly just stranding it.
Interplanar Dragons are wingless, but fly under their own power. They are long and serpentine, and their scales glint rainbow and white. They can speak draconic, common and their own language.
