Goethia (aka. Sprites)

Goethia/Sprites are a kind idea living a life of it's own. They are independant intelligences formed from thought and ideas and come in many different forms. In many ways they can be compared to spirits, but they are normally easier understood and less alien than spirits as they are formed from and by human thought.
Goethias can come from the collective unconscious, the imagination, or even from the dreams of others. They can also be created by a sufficiently powerfule mind mage. If a goethia is a representation of a facet of a mage's sould, like e.g. the emotion anger, the mages loses this part of himself as long as the goethia is outside his personal astral space (Oneiros).
