What is a maester?

A maester is a learned and trained individual in the fictional world of "Game of Thrones" and "A Song of Ice and Fire" series written by George R.R. Martin. Maesters are typically found in the Seven Kingdoms of Westeros and are members of the Order of Maesters, which is based at the Citadel in Oldtown.

Maesters are scholars and advisors, serving noble families as tutors, healers, and counselors. They wear distinctive chains made of different metals that represent their areas of expertise, such as black iron for ravenry, silver for healing, gold for economics, and so on.

Maesters are trained in a wide range of subjects, including history, medicine, astronomy, and warfare. They are expected to remain neutral and impartial in political matters and are bound by a vow of loyalty to the realm rather than to any specific noble house.

Maesters are also responsible for managing the ravens used for long-distance communication in Westeros. They are highly respected and play a crucial role in the governance and stability of the Seven Kingdoms.
