With the knowledge of the otherdimensional, we were finally able to piece together how the demons work. Spiderdemon's huge brain must be an antenna, through which it draws energy (and, possibly, orders) from some other dimension. Namely, from Hell itself. This must be the same process the other demons are using, and the Demonic Essence must be a catalyst. This implies the demons and their works can appear anywhere, at any time.
