Ritual interrupted by allies' desperate strike

The Doctor is dragged toward the flames as the Master smugly declares the Doctor's ultimate sacrifice to Logar, robbing him of future encounters. Before Timanov can complete the ritual, Turlough, Peri, and Malkon burst forward, disrupting the ceremony. The Elder Council falls into chaos as hands that once pushed victims now draw weapons. The assault halts the Master's scheme at its most vulnerable point, forcing him to fight openly on multiple fronts while his pawns scramble to regain control. Turlough's unexpected intervention introduces a personal stake that may unravel the Master's web of control over Sarn's leaders. Malkon's choice to defy tradition endangers his standing but becomes the first real fracture in the Master's plan.
