The capacity and responsibilities of the rank are not known, but the name suggests expertise and possibly taking one or more apprentices. Within his own craft, a Master's word was as law. They had mostly supervisory roles in their Guild or were assistants to the Grand Master. Few of them were elected to the Guild Council. It is not known how many Guild Masters there were in a Guild. Possibly a Grand Master was selected from the available Guild Masters.
Most Guild Masters did not agree with Lanaren's demand to rewrite the Ages that were operated by outsiders knowing that the plan would take years and years but nonetheless, they agreed to attempt it.
