The Fires of the Earth are some kind of demon or spirit in Killswitch. It is believed that they had some sort of steam jet attack, and could cause workers to hallucinate due to fumes, change in size, or even become undead. The Fires were also noted to be able to possess inanimate objects, such as coal grinders.[1]

Ghast was one of the Fires, and it is believed that Porto inhaled Ghast and absorbed him, therefore gaining her size-changing properties.[1]
