The world is filled with a great variety of monstrous creatures, not all of whom have the same origin or cause. Many result from interference in the world by the demons of Hell, others by wicked experiments of magicians and alchemists.

Disembodied Spirits: (Spirits)

• Ghosts: the souls of dead mortals who have not yet departed and linger in the Spirit World.
• Spirits: the inhabitants of the Spirit World, often associated with the Spiritual Aspects of features of the Mundane World.
• Demons: these are evil-aligned spirits from the Second World, who constantly attempt to infiltrate the Mundane World, but who are often found in the Spirit World, as it is far easier to access.
• Angels: these are the messenger-spirits sent by the powers of the Realm of Light.

Monsters by Intrusion of Evil Spirits into Bodies (Intruders)

• The Blood-Embodied: evil rituals can give demonic spirits their own physical bodies, which can reproduce after a fashion, bringing more demons into the Mundane World. Common Examples are Imps and Pit Spawn.
• Trolls: the term troll is a convenient label for creatures that arose from carnal relations between evil spirits and mortal creatures. The Biblical Nephilim would be a convenient synonym, as would “the Race of Cain” for humanoid trolls. These beings usually appear as misshapen or twisted versions of their mortal ancestor's species.
• Undead: when a disembodied spirit (usually a demon, sometimes a ghost) possesses a corpse and gives it motion (but not actual life) and uses it as a puppet to interact with the world, it is called Undead.
• Possessed: when a spirit controls a living being, whether through temporary control or by extinguishing or expelling its native spirt, the new creature is called possessed.

Abominations:

• Atlantean Abominations: a creature, such as the dreaded Hooger, is one created by manipulating the bodies of various creatures to create horrible hybrid species that breed and spread across the world.
• Lycanthrope: mortals cursed by magical disease and forced to live as a mercurial monster not truly beast nor truly human.
• Magic Abominations: creatures, like dragons, are created when magical or demonic forces warp and transform natural creatures into huge monsters with unnatural powers.

Fairies

Fairies are beings that are simultaneously Spirits and Physical beings and can transition between both states.

• Elves: members of courts of sophisticated human like beings of the Spirit World
• Wee Folk: sprites, leprechauns, pixies, etc
• Jotuns: a powerful race said to be close kin and rivals to the Aesir gods. They have great strength, elemental and magic powers.
• Jinn: spiritual beings who are able to enter the physical world in the form of dogs or serpents or completely invisible humanoids and who have a love of possessing humans

Constructs

Constructs are made, not born. Some are programmed by their creators to follow a simple set of instructions, while others are imbued with sentience and capable of independent thought.

• Golems: Iconic constructs imbued with life by their creator to live until the dawn
• Animated Item: The souls of the living powers the magic to imbue mundane items with eternal sentient life
• Automaton: Atlantean magic often powered many items to move and act with a semblance of life, but they are instead complex items or traps
• Graven Image: when a carved statue is honored, worshipped and given sacrifice, it sometimes is inhabited by a demon, through some astrological process, and gains the power to speak, move AND KILL!
