The Guildmaster was the leader of the Hero's Guild in Albion during the events of the original Fable. He frequently uses the Guild Seal to communicate with other Heroes, offering quests and advice as well as giving regular updates.
In the original Fable, the Guildmaster is introduced when the Hero first arrives at the Hero's Guild accompanied by Maze. The Guildmaster then leads the boy to his bed, who begins to sob uncontrollably after the Guildmaster leaves.
Sometime later, the Hero is rudely woken up by another Hero called Whisper, who challenges him to reach the Guildmaster first. When the Hero meets up with the Guildmaster outside, he introduces the Hero in the steps towards basic combat.
