Necromalus

The evil from the Underworld has corrupted mankind for thousands of years. Demons and monsters from our worst nightmares spring forth out of the darkness to rip the souls from our bodies. They seek to disrupt the very energy of life itself and by doing so, corrupt the Earth completely.

Thousands of years ago, they were driven off by the five Masters and the so called Glowing Man. However, the creatures of the Underworld have finally found a way back to Earth. A Demon Lord called Necromalus leads the assault, taking back the Earth piece by piece with his near limitless armies of demons, monsters, and undead. Only the Masters of the Tranquil Mind stand in their way from having the Earth plunged into darkness once more.
