Ambril and Tanha enter the Cave of Origins

Ambril leads Tanha through the cavernous maw of the ancient cave system, its dark entrance framed by Manussa's eroded sandstone. Tanha voices her forgotten awe for the site, signaling her gradual shift from skepticism to reverence for the planet's buried histories. Their crossing of the threshold into the cave's yawning dark marks both a physical descent and a psychological plunging toward the Mara's buried secrets, where Tegan's latent connection threatens to ignite the ancient entity's dormant power. The moment sets the stage for the Doctor's confrontation with the dream-anchored menace and the unraveling of Manussa's fragile safety. key_dialogue: [ AMBRIL: The main entrance to the cave system itself.
