Siege of the Wallpeaks is the fifth scenario in the Warlords of the Wasteland. On his way to attack the Empire of Bracaduun, Tarnum needs to pass through the Wallpeaks, a mountain range filled with castles. It's considered impossible to get through the pass, and one of Tarnum's shamans tells him that he will die, unless the gathers the four parts of the Titan's Thunder. His army is regularly ambushed by a group of wizards, but Tordac, son of Tarnum's friend Hardac, suggests setting a trap for them. The trap succeeds, but Tordac is killed in the fight.
