Thunderfist and the Dragon

The mountain dwarves of Balgavarr Reaches hold territory the neighboring Uruzak kingdom wants. When a presumptuous lava elf from Uruzak forms an alliance with the goblins of the Big Wet, a new and terrifying force grants the dwarves' enemy the key to an ancient evil: a plan to resurrect the elder dragon who once plagued the mountains and nearly drove the dwarves from their home once before.
