The Nightmares Underneath
An old-school role-playing game set in a fantasy Middle East where otherworldly nightmares invade the physical world as dungeons seeking to undermine civilization. Players create characters with classes and levels, explore these incursions, and gain experience from recovered treasure. The game uses six attributes rolled with 3d6, memorized spells, and simple roll-under tests for saves and skills.
