Radiant Servants demonstrate the strength of good through charity and modesty. While it seems a contradiction, the point is that the truly strong don't need to prove their power. Their priests and their flocks perform so many good acts that evil has no room to exist, but they acknowledges that there are times when evil must be defeated in direct confrontation. The radiant servants put this dogma into living practice. As the name implies, the brothers and sisters of the radiant servants are sworn to serve - to minister to the needs of their followers and good-hearted people everywhere. While combating evil, particularly undead, is an important part of that service, it is by no means the only part. Radiant servants are healers, counselors, sources of spiritual and (at times) financial support, and protectors.
Almost all radiant servants spend their prior careers as clerics.
