The Mages' Guild is lead by Rossel.[1]
History[]
Rossel invited, or more correctly requested, Vandalieu to join the mages' guild, which the boy eventually accepted. “Wouldn’t I need to be an apprentice of a current member or have a letter of recommendation if I’m to join the Mages’ Guild?” Vandalieu asked. “I shall write your letter of recommendation,” Rossel said. “Of course, we will not do anything unreasonable like demanding that you teach us how to create transformation equipment because you are a member. Unlike the craftsmen's guild, the purpose of the Mages’ Guild is not mutual improvement through the sharing of techniques. Having secrets is an essential part of being a mage or alchemist.”[1]
"Vandalieu had assumed that the Mages’ Guild was like a specialized school of magic or research organization, but it seemed that members had more freedom than he thought. They did share knowledge, but the sharing of their secret arts and techniques was reserved for their apprentices. Thus, in order to learn someone else’s secrets, one would have to either steal them or devise a way to reproduce them on their own. If neither of these was possible, then one would need to offer a trade or politely ask to become an apprentice."[1]
“I understand. But I have a question about the paperwork involved when I register,” said Vandalieu. “It’s about your Guild Card and Status, isn’t it? Rest assured – if we create your Guild Card based on your Commerce Guild Card, nobody will see your Status,” said Rossel. "The process of registering at the Mages’ Guild and Craftsmen’s Guild was more difficult compared to that of other Guilds. It was conventional for the applicant’s master or person who had given their letter of recommendation to investigate the applicant while they were still an apprentice."[1]
