In 1124 the Legislator Ti'lanar wrote a paper titled "Minor Guilds" in which he criticized the contemporary syte in which only a small elite of D'ni people are able to learn and keep the traditions through the existing Major Guilds, while more people remain ignorant and uneducated. He proposed the formation of Minor Guilds, that would further the knowledge beyond that already provided.
King Mararon agreed with the paper and followed its suggestions to reform the D'ni education system, in which D'ni boys could enter any of the new Minor Guilds after finishing education in the Common Schools.
Only men were eligible for Minor Guild education. Women, such as actresses, participated in the Minor Guilds although they had never been officially recognized as members.
Around 2488 King Naygen (whose major causes were to boost mining as well as the arts) elevated the Guild of Miners to the status of a Major Guild replacing the Major Guild of Fine Artists, which was split into several artistic Minor Guilds.
