Tulpa
Tulpas are beings born from the human psyche, used to channel Qì by the denizens of Realm 108, as they cannot harness it directly. People who use Tulpas, regardless of whether or not they created them, are known as Tulpamancers.
Birth
A Tulpa is willed into existence by a person (or people) and undergoes a life cycle where it displays different characteristics. A Tulpa enters the world as disembodied voices and a presence only its creator(s) can hear/feel. If acknowledged and interacted with enough, the Tulpa will then gradually gain a physical form at a rate depending on how much energy the creator(s) have and are willing and able to spend on it, as well as how often it interacts with them. First, it takes the form a levitating blob of colour only its creator(s) can see, but can subtly affect objects such as knocking objects around, and then it slowly forms itself according to the creator(s)' personality. When it has a fully physical form, it can then be seen by others and use its powers properly.
