I know that you don't have an answer as to where/what the epicenter of the Great Six may be when it comes to medicine/doctors, but where do most people generally congregate to learn to become doctors, if such a place exists? Do doctors have any kind of oversight, whether it be based where they're working (such as Doctor Gorri in Dormeho/his boss (see: medical head) being overseen by a board of sorts on Sigrogana) to keep ethics and accountability? And what is the upper limit of knowledge/skill a physician (general) and a specialist physician (such as a surgeon) would be able to reasonably attain/have, considering that the world is very much fueled by magic?

I know it's a loaded question based on some unknowns, but this has been a hot topic for a few years now as well.
