of them, causing their affliction to be passed on to one of the three survivors. Butler, venturing out to the edge of town in pursuit of one of the feral miners, discovers a row of severed heads mounted on spikes, including the head of Commander Braddock, and a large assembly in the canyon below committing horrific acts of self-mutilation and ritualistic execution. Desolation's associates soon arrive and force Ballard and Butler to release him. While they originally plan on leaving the officers and remaining miners to die, Ballard convinces them to work together to survive. Their initial effort to escape is halted when the army of feral miners converge on their position, killing, injuring and infecting several of their number. Confronted by Ballard, Whitlock eventually explains that she fled from her post after discovering an ancient underground vault created by an extinct Martian civilization.

While they are able to initiate the meltdown, Whitlock is possessed, while Butler, Kincaid and the two train operators are killed. Boarding the train, the two watch as the army is engulfed in the explosion. Desolation tends to Ballard's wounds. Unwilling to face the authorities, he handcuffs Ballard to her cot and leaves. She moves to shoot him, but realizes her respect for him and lets him make his escape. Resting after her tribunal, Ballard is woken by an alert that the city is under attack. Realizing their attempt to destroy the spirits failed, she readies herself to face the onslaught alone until she is greeted by Desolation, who hands her a weapon. The two agree to
