Pyrodine

Pyrodines were fire like creatures that were freed by a Proto-morphic lifeform under the command of Morjanus. They emerged from Gas lamps and killed a Policeman called Bates. They were immune to psychic attacks. Morjanus intended that they would burn the city to the ground. They were destroyed when the Proto-morphic life form was destroyed.
