Swirls of smoke rose from the slits of his visor, and he cooked inside his armor. Ce'Nedra, the Light Queen, clutched her amulet and closed her eyes: "Help us, Belgarath! We're going to be crushed!" What was the point of calling him? He had probably reached the City of Night, where Torak was awakening amidst the ruins. The immense gesture was ending in the clash of weapons, and the child of prophecy was not ready. The seven-thousand-year war would end with the victory of the Dragon God of the Angaraks!
