Saecula Mutata

From the introduction: On a planet called Wiskedak (Wis-ke-dak), human civilization reached a fast paced technological enlightenment period. Knowledge and devices from this period are still not yet understood and almost seem like fanciful magic to the inhabitants now. User summary: The post-apocalyptic setting of Saecula Mutata is the primary setting for the D10/0 System game. Early in development it was referred to as Shattered Earth; this name was changed to distinguish it from other similar settings.
