Horrible creatures, hulking and deadly. They come from liminal spaces, you know. The borders between the planes themselves, and it is said they feast on meat and souls. No-one knows where they came from originally, maybe they've always been here? Maybe they're a freak mutation of some planar traveller's abandoned animal companion? Theories abound, but that doesn't stop them appearing from nowhere to slaughter and feed and then disappear without a trace. Some intrepid fools look to hunt them themselves, because it is said that the heart of one of these beasts holds great potential and when treated appropriately can become... anything. Or so they say, this is enough of a rumour to make people want to try. They used to be much rarer. But something has happened to the planar boundaries, the fabric of reality itself, and it's letting them in. Perhaps they're only the vanguard of something much, much worse. Instinct: To feast

• Burst forth from another plane or escape to another
• Tear out the soul with its jaws
• Track its prey through supernatural means
• Call forth others from beyond the world
• Devour the souls of those it kills.
