The Cosians have been blessed with the least ambiguous success of any of the conventions. The widespread treatment of disease and illness is an ongoing mission but one which the Circle has risen to time and time again. As the battle gets more difficult, there is a change occuring in the focus and structure of the group in an attempt to defeat its foe. Like the High Guild, the Cosians are finding itself with fewer members who are practicing doctors and surgeons and more who are researchers, biologists, and theorists. Stepping back from the practice of medicine, they have turned this task over to Sleeper physicians and dedicated itself to the expansion of medical knowledge.
In terms of the rift in the Order, Cosians have found themselves on either side of the disagreement. More conservative members of the convention are unwilling to discard the religious and humanitarian mission set forth by the Craftmasons and dislike the move of their own convention away from alleviating the suffering of patients and towards the detached pursuit of medical research. On the other side are the more progessive thinking members who believe that the good they can do is inherently limited as surgeons and that they most good for the most people can only be achieved by focusing on larger issues than individual patients' illnesses. The argument is mostly civil, but can get quite heated, particularly when one side accuses the other of short-sightedness or, worse, shaky ethics.
The Cosians main meeting place is the Royal College of Surgeons, though non-practicing members congregate at the Royal Society meeting place in Burlington House. The Circle's structure is very academic and this is reflected in their meetings, which just as often revolve around lectures and surgical demonstrations as they do around politics.
