God of Ore by Tom Knauss
God of Ore is an adventure for 3rd-level characters that takes them from the quiet¸ mountainside town of Miners' Refuge into the heart of the Stoneheart Mountains in pursuit of a failed pilgrimage to discover a phony religious relic deep inside legendary Mithral Mountain. The dark¸ twisting tunnels that bore into the fabled mountain soon reveal that some mysteries are not what they first appear to be.
