The Copper Caves
The Copper Caves is a simple dungeon-crawling setting for any table-top role-playing game like Dungeons & Dragons. It is designed to be procedurally generated with a progressive challenge as the players delve deeper into the caves.
Setting: The Copper Caves have long been a source of material for industrialists and beauty for naturalists. But in these latter years the monstrous spider Ashlaw and her thousands of offspring have infested the caves bringing an end to their use and enjoyment. Now they lay dormant, the spiders patiently waiting to claim their next victim.
Many adventurers enter the Copper Caves in search of treasure but few return.
