The Cleric's Guild of Shajin was a sect of magic-users who produced clerics that served in a religious capacity. Their primary job was to allocate clerics to various religious orders who would use magic in connection with the divine. They performed blessings, enchantments, and ceremonies, as well as healing and protection. They also drove out evil spirits and performed oracles.
It was the Guild who got the Ygwer Code adopted as a universal standard of behavior amongst the schools, as the code was in use since the inception of the Ygwer School of Clerics. The compromise to accepting the code universally was to create a multi-discipline tribunal which had one representative each from the five major schools. A task force to support the tribunal was also created with agents from each of the disciplines called the Joint Illition Directorate. It was also the Guild who built and ran Ke'phal Prison, which was the only facility capable of holding magickers of any power.
