Nyssa resists Xeraphin absorption at sarcophagus

Nyssa succumbs to the Xeraphin’s irresistible call and steps toward the sarcophagus, risking assimilation into its infinite knowledge. The Doctor warns of her destruction, but she insists the sacrifice is necessary to save them all. Professor Hayter, drawn by the same psychic lure, ignores all cautions and approaches the glowing entity. A blinding burst engulfs him as the Xeraphin absorbs his consciousness, escalating the stakes and confirming the perilous proximity of the Master’s plan. Nyssa’s near-brush with annihilation exposes the Xeraphin’s dual nature—benevolent enlightenment versus annihilating absorption—while the Doctor’s failed intervention underscores the entity’s coercive power. key_dialogue: [ NYSSA: The power's returning. Can't you feel it? DOCTOR: No, Nyssa, you'll be absorbed. NYSSA: The Xeraphin contains the wisdom of the universe. Without the knowledge, you cannot escape from the sanctum. DOCTOR: But the knowledge will consume you! NYSSA: The sacrifice is required for your survival, Doctor, and the future of the Xeraphin. DOCTOR: Professor Hayter, get back from there! ]
