Mythos adjacent Seal Perdition is a fictional town in the DC universe which first appeared in 1974 in issue #8 of the 1st volume of the Swamp Thing comic series.


Perdition is a mining community in Pennsylvania's Appalachian mountains. In 1904 the mystical spell book Visions of a Dead Priest was discovered by Abraham Monroe. He opened a doorway which gave M'nagalah access to Earth. It took up residence in one of the mine shafts and for over 70 years the town experienced a reign of terror, until the mystical super hero, the Swamp Thing put an end to its reign.
