Grey or brown, but honestly any colour, these are the Goblins, Gremlins, Faeries and Boggarts of legend. Tiny, vicious, and always on the lookout for more food. An Oversized head on top of a small mound of rags, they swarm around the adventurer and force them to kneel or fall before overwhelming them. Instinct: To feed on what is available

Instinct: to hunt demons

• Strike with a Flaming Lance

The most well-known monster of em all. It can be found basically everywhere, because it doesn't care. It just exists for some unknown reason, wandering the world until someone or something sets an end to it. Unfortunately if you kill one you can be sure to find 10 new around the next corner; they're like rats, but far more creepy. Good that they don't also carry some sort of virus - not until today at least. Instinct: Follow, hunt, eat

• Hunt the living
• call nearby monsters for support

This seething devil deftly wields a vicious, saw-toothed glaive, while below its toothy maw writhes a hideous, twitching beard. (5e SRD) Instinct: to serve the Archdevils

• Strike with Poisoned Glaive

The Death Worm is a 40 ft multicoloured worm with a deadly appetite. They are known to live both on Land and at sea. Revered as the living embodiment of the god Khor by some cults, they are an ancient species older than any known sentient being. It is unknown to what extent these monsters are able to think. They are opportunistic hunters, often lurking beneath the surface of the ground or seabed, ready to spring out and catch unsuspecting prey. It is rumored that the largest of these creatures are able to swallow a large ship whole. Instinct: Hungry

• It lurks beneath the surface of the ground or seabed waiting for unsuspecting prey to pass.
• It's blood is a thick brown substance, thought to be toxic
• It's blood may or may not cause visions of the future if consumed

Crawler is a giant centipede from a demonic plane. It is as high as a horses back and many times as long. Its back covered in thick bone plates, that withstand all the weapons of man. It lost its sight as part of becoming a demon and only a terrifying bloody mass is left in the sockets. With large, strange looking antennas and sensitive forelegs it can sense the presence of other beings by their vibrations in the ground. The bone plates on head and back are in a dark brown and covered in disturbing demonic symbols that tell from its transformation. The sheer pleasure to kill and scent ability make it a perfect hunter for which it is usually summoned. The weaker belly is of a milky white, but it's hard to attack directly. It only willingly exposes it when rearing up to dive down on its prey, but who wants to get right under its terrifying mandibles? Attacking the back is useless without a mean to get in the narrow slits between the bone plates. Instinct: Killing

• Rear up and dive down on your prey
• Open little portals to summon a bunch (2d4) of small, fyling demons, that attack its enemies
• Burrow

The Racedis Arena Instinct: To gain power through glory

• Absorb adoration for power

Selkies mean no harm - not intentionally. It may happen, however, that they simply forget about the needs of air-breathing land creatures when they invite them to have a refreshing swim in the deep waters. Instinct: to live a life of curiousity and joy

• Shed her seal skin and leave the water
• Swim with overpowering joy and forget about breathing for a while
• Lure someone into the water

Whether it be foul curse, communicable disease, or genetic disorder, this creature spends most of its life as a human. Perhaps it's completely unaware of what happens when the moonlight strikes it, or maybe it just pretends not to know. In either case, when struck by moonlight, the creature undergoes a terrifying transformation to become a feral, bloodthirsty wolf. Bigger than any natural wolf, and as smart as a man, the werewolf draws normal wolves to it like moths to a flame. A true terror of the night. Instinct: to devour the flesh of sentient creatures

• Spread lycanthropy
• Seize and shake like a ragdoll
• Howl for the pack

A dangerous species of cave-centipedes. Lures prey by hiding in the dark and in shallow water with only small, fluorescent, mushroom-like antennasm sticking out. Instinct: to protect the younglings

• Roaming caves, breeding.
• hide & deceive to ambush prey
