Xeraphin power exposed in sealed chamber

Trapped within the sanctum by the Master’s hand, the Doctor and his companions grapple with the realization that the walls sealing them are not merely physical but psychically wrought. As Tegan voices disbelief over the suffocating enclosure, the Doctor identifies the force behind it—the dying consciousness of the Xeraphin, an extinct race of beings whose residual mental might now shapes their prison. Hayter’s discovery of the statuettes reveals the chamber’s sacred purpose and the Master’s weaponized echoes of a lost civilization. Nyssa’s insight ties the artifacts to the tissue compressor, exposing the full horror of the Master’s scheme. Together they confront that the Xeraphin’s latent power, now awakening through cellular fusion, is both the source of their entombment and the weapon the Master seeks to wield. key_dialogue: [ DOCTOR: The Xeraphin. NYSSA: The work of a tissue compression eliminator. DOCTOR: No wonder the animus is so strong. Apart from the Master's victims, the entire race of the Xeraphin is in this sarcophagus. ]
