Spirits summoned to do their master’s bidding and pacified with powerful magic focused on that part of the servant spirit’s soul. When respected and freed quickly, they are often not dangerous to the summoner. But if they are treated as a slave or kept for long periods of time they resist pacification and turn on their master, exacting a terrible revenge.
It is best to bind the spirit to a paper figure or another item, for ease of control and to be able to utilize the ki from the binding item in helping to keep the spirit soothed. The paper’s ki is limited, so the spirit knows it won’t be bound for long and can return to the Spirit Realm without much delay.
This school of magic receives mixed reactions from the magic user community. While it was created to provide helpers for the summoner, it has been used for many a dark deed that a summoner didn’t wish to do themselves—tainting the servant and master.
