Gui was a Premier in the Aquilan service during the Age of Edification. Before climbing to power, Premiere Gui's initial rank in the Aquilan service was a lowly Pasoft. He presumably ruled the city of Kaina. He was a brutal ruler who enslaved those who lived under him.

In the Aquilan Fable, an altruistic felon named Sjazier incited Kaina to riot against Pasoft, and Sjazier assassinated Pasoft.
