there, two of mordenkainen's allies, the warrior lord robilar, and boccobite cleric riggby, found the imprisoned iuz and through mordenkainen's manipulation, released the half-demon believing they could just kill him outright once and for all. iuz, however, managed to escape the battle and fled back to his kingdom where he could recover his power and plot his revenge against his enemies. afterward, robilar, along with the archmage rary, betrayed mordenkainen and the circle of eight (a committee of wizards), by killing the great wizards tenser and otiluke, and leaving bigby clinging to life. mordenkainen had expected rary to betray him sooner or later, but not robilar, who was his trusted ally for decades.
