The High College of Arcanists is, formally speaking, the name of both an organization and a physical establishment / building within the Empire. The College is the school which trains all Arcanists - i.e. users of Magic - within the state, helping them to develop their talents. Many Arcanists go on to become Magisters of one sort or another, while others retain the former title and are often attached to the military or given special assignments. Others sell their unique talents in more benign ways to craft special weapons, charms or somesuch. Magic is not restricted by law within the Empire in the same way that it would be in many other states but the talent is extremely rare - many of those who possess the apptitudes to develop the skills are killed during their terms of military service or simply choose never to follow down that path.
