The Kryptonian Mediator Guild is one of the five primary guild houses found on the planet Krypton. Its members were bio-engineered from birth to be religious leaders (worshiping the Kryptonian god Rao) as well as magistrates, among other things.
History
The Mediator Guild had existed for over 100,000 years, from when Kryptonian civilization began to advance. Many noted religious and law leaders came from the guild and were instrumental in furthering Kryptonian culture.
