Apparently, they are part to a dark cult connected to a previously unheard deity called "The Great Dismembered".
It is told that these "physicians" are able to perform bloody dismemberment rituals that allow a so called "patient" to obtain certain powers over a "donor" exchanging, by cutting and sewing, the flesh and the bones of the first with the second.
The strength, type and magnitude of the obtained powers depend on what parts of the body are replaced, and of course the kind of ritual performed.
Both the patient and the donor are magically kept alive during the ritual, but after it is completed it is not sure whether one of them or both will stay alive and for how long, or if sides effects will occur, as the procedure is very dangerous.
Someone even says that if the donor dies the patient will be able to retain these powers over his corpse, and sometimes even get total control of it.
The collateral effect is, however, the slow but inexorable mental deterioration of the patient caused by the connection to the corpse. This will not cause the patient's death.
On the contrary, if the one who dies is the patient , the donor will suffer from a terrible mental break, and his body will start to rot until death arrives after a long agony.
None of this of course has been ever documented and of course no proof whatsoever exists, and those who swear have seen these rituals or the people involved are usually madman or drunkards, or are bound to suffer a terrible death within days or even hours from their telling.
Their bodies are always missing parts.
