While their origin is unknown, multiple re-animated corpses were found on a parallel Earth by the unnamed brunette woman and Thomas while attempting to dispose of the Soul Reader (Book). These re-animated corpses were only visible when under direct light, otherwise they remained invisible. The corpses appeared to have been reanimated through the influence of a large mobile metallic construct.

The same re-animated corpses and gargantuan metallic construct were later encountered by refugees fleeing inwards from the effects of The Crushing Fist. The controlling entity is enormous in size, with mobile metal legs stretching up above cloud height.

Traits: Invisible unless under bright direct light from a flashlight or lightning. Displays hostile intentions and attacks living creatures when alerted to their presence. Remotely controlled from a massive metallic construct of unknown origin and incapable of independent operation.
