I thought that the Grand Maester was the "official" head, while the Conclave are the "de facto" leadership due to the Grand Maester residing at King's Landing. Was there even a Grand Maester before the Targaryen Conquest?--The Dragon Demands (talk) 21:44, September 8, 2012 (UTC)

Nope. The Grand Maester is "Grand" just cause he advises the King. He's not the equivalent of the High Septon or anything. There's no specific mention of Grand Maesters before the Conquest.-- 00:01, September 9, 2012 (UTC)
