Tulpa, or Psychogone – a spirit created or summoned (consciously or not) by a particular person for their personal use. A personification of a personal, subconscious archetype.
Familiars are astral teachers, guides, and companions, through which the magickal arts may be performed non-corporeally. Commonly associated with animal or mythical beast forms (including dragons), they can take many forms, or even be seen as shapeshifters (taking the form necessary to the situation).
Guardians are another form of spirit guide—a teacher and protector. Generally understood to be called, summoned, or otherwise petitioned and not created. More human-like than familiars; often perceived as angels, demons, jinn, and faeries.
Servitors are specifically created for a declared purpose—guards, spies, hunters, test subjects, effigies, etc. They may be created in any form as needed for the intended work.
Homunculi are the result of alchemical generation—physical (as metaphor), mental, or spiritual/emotional. In this case, the process of creation holds as much power and meaning as the creation itself.
Soul, or Layer of Being – personal thoughtforms of the self, through which the living interact with reality—physical, emotional, mental, or collective: Name, Body (as a TF, one’s awareness and perception of one’s physical self), Living Spirit, Shadow, Persona, Ego, Anima, Self-Soul and even Monad (as a TF, one’s personal connection to and associations with of the One).
Haunt – a spirit or spiritual energy that lingers in a place or in connection to an object (or possibly even a living person).
Apparitions, or Echoes, are emotional leftovers—emotional energy stamped on a place, item, or even person. They can manifest as an image, a smell, a sound, or even a moving scene. A particularly traumatic or emotional event can linger in its entirety; and they can be left by people who are still living. While not sentient, echoes make up the majority of para-normal experiences we encounter.
Ghosts are “spirits” in the traditional sense; they are the consciousnesses (one [or more] of the souls, see above) of people who have died: They are sentient and can interact with the living. As people, they retain their personalities. These beings can be interacted with as if they were living people.
Poltergeists are accidental thoughtforms—strong emotions that have gained sentience. Capable of interacting with the phsical world, they represent some of the most dangerous haunts.
