However, the Avernics stationed in Gielinor began to harbour rebellious thoughts against their Chthonian leaders, who resided in distant luxury. Zamorak used this dissatisfaction to sway the Avernics to his side, including two Tsutsaroth who were willing to pledge their allegiance to him. In time, Zamorak would use many Avernic in his rebellion against Zaros. Amongst them were the Tsutsaroth Thammaron and Zebub. With Zamorak's victory over Zaros, the surviving demons opened a portal and took Zamorak with them to Infernus to fulfill his part of the bargain.
