Order of the Maesters

The Order of the Maesters was an all-male order of scholars, healers, messengers, and scientists. As a result, they were often known as the knights of the mind. Their headquarters, where they educated students and trained new Maesters, was known as the Citadel, which was located in Oldtown, a city in the Reach of Westeros. They served primarily as advisors to the lords and s of Westeros. Their primary rivals to this capacity were the Alchemist's Guild.
