Object
Taltarian Airlock
The Taltarian airlock traps Ian and Vicki amid the Aridians' overrun underwater cities, now infested by flesh-eating Mire Beasts. Aridians like Malsan and Rynian set charges to detonate it at high suns, entombing the beasts in rubble. Doctor and Barbara press for rescue as Prondyn warns of imminent explosion; Malsan risks the blast to reach it, turning the structure into a dual peril of beasts and detonation.
