Here's an excerpt from the review:
Torchlight is a little town positioned near the entrance of an extensive range of caverns. Within these caverns are veins of a very special material called Ember. This magical mineral can be used to infuse weapons and armor with magical abilities that greatly enhance their value and effectiveness. Trade went well for Torchlight until the day someone delved too deep and exposed something very evil. Now unusual creatures roam the mines, attacking and scaring away the miners. And so the people of Torchlight looked toward heroes to enter the mines and try to stop the madness.
