RPG Ring Of Demon

Story:
Four young men wore Devil Rings, and donned powerful, enchanted armor. They waged war with each other as some kind of sick competition. While civilian casualties were at a relative minimum, their rings and armor were sealed by a legendary magician. So reliant on the power of those artifact, the four men were utterly devastated, laid down their arms, and the land knew a brief peace.

Five years have passed since then. The seal on the rings and armor have been broken. Forces gather to obtain their great power. One is headed by a witch, who lives in a black tower. Another is headed by a sorcerer. A third is headed by a self-proclaimed king of darkness. Even the former bearers of the artifacts, ever obsessed with their power, make an effort to re-obtain them. With war moving with inevitability, the question becomes if the world will ever be safe again.
