The Portal in the Forest
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.
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.
