Hex Crawl Chronicles 6

There was a time when crystal domes dotted the landscape of the Troll Hills and sky sleds cut through the air like ships through the waves. That was long ago. The ancient, golden-skinned men, they say, built their domes too near the great lake from which all life sprang, and so the lake spawned the trolls and more fearsome creatures to punish the ancient men. Whatever the truth is, the ancient men were laid low, the cities crumbled, the survivors turned out into the wilderness and the hills were left to the trolls.
