The Union of Sages and Academics

  This union is a loose confederation of sages and academics who form the basis of tutelage at the University of Greyhawk, known more commonly as Grey College.  Unlike many of the other guilds and unions within the city, the Sages and Academics Union has no monopoly and the majority of the Unions membership consists of those who merely partake of the sumptuous feasts on each of the city's festival days.
  The University is closed for summer vacation between the first day of Richfest and the first day of Brewfest, during which period the majority of the union's membership leave the city to undertake research for a variety of rich patrons.  During the academic year, some 1,000 students swell the population of the Free City, mostly living in rooms and apartments in Clerkberg.  Since most of these students are well off, and since the sages bring other wealthy persons into Greyhawk seeking consultations, the University pays only nominal taxes to the city coffers.  The sages are typically unwordly men, not given to involvement in politics, which they regard as vulgar.
  Since the sages and savants of Greyhawk are the most knowledgeable in the Flanaess, the University probably has a sage who could answer virtually any query on any subject, given the time, the money (lots of it) and a remarkable patience with stuborness and a cantankerous temperament.
  Sages often view answering such queries as something they only do for money and they are used to talking down to their students.
