Both The Realm and Darin has many different organisations, Guilds, and other collections of individuals. Some are well known to the commoner while others try to exist in secrecy. Some huge in numbers and others but a score or fewer very powerful individuals. Common to all is that they work to bend reality towards their own view of a better world.
Common for all though, is that they strife to uphold the highest standards of their ‘trade’, and banish those who fail to act by their, often very strict, rules and laws. They also, with the blessing of nobility through out the world, hunt down and punish impostors.
