Each Psychic School has a Council that are in charge of running the ship. They have many responsibilities, including: where the school goes, the school’s curriculum, missions to accept, and observation of students with exceptional/rare abilities. How the Council is made up is different in each school, but the Council of Aquarius is made up of four members.
Two members are psychics, usually more experienced (read: older) than the rest, but elected by popular vote of the psychic population. The other two members are non-psychics, chosen in the same way by non-psychics. These four debate and make decisions among each other. In the event of a tied vote between them, and no hope of reconciliation, the decision is thrust upon the Captain of Aquarius. The Captain, while not a member of the Council, is kept in the loop on their debate topics, and is in charge of the day-to-day running of the ship. At the moment, the Captain is a non-psychic user, but is generally considered to be fairly moderate in his leanings.
