Balustan was one of the last five surviving Dragon Riders on Gielinor. Shortly before the banishment of their master Zaros, the Dragon Riders were approached by Zamorak, one of the Empty Lord's generals, who was planning to take his place as a god. Though two of their number - Morvannon and Apropos - agreed to defect to Zamorak, Balustan remained loyal to Zaros, along with Ablenkian, and considered warning the Empty Lord of the plot against him. Despite his maintained allegiance, when Zaros was banished, Balustan was branded a traitor by the Empty Lord's remaining followers and was eventually hunted down and torn apart by a number of Zarosian ripper demons.
