Once simply a Serpent Guard in Selket's ranks, Asul rose to eventually become his god's First Prime. He served in this position for many years and, despite having proven his worth time and time again to Selket, he never earned the trust of his god. Indeed, Selket's paranoia was so great that she kept Asul's children and grandchildren on a different planet where they were under constant guard and surveillance so that, if Asul ever failed her, she would have a bargaining chip. It was because of this type of trust that Asul eventually lost respect for Selket, though his innate loyalty would not let him question her orders or manner of rule over her dominion.
