Maud Pie, head of Equestria's rock department, is trusted with all of the country's deepest secrets. The only ones who know more are the princesses. If you want to know what she does, you need only ask. But do you want to know the answers?

Two stallions, hard up on cash, volunteer to accompany Maud on a dangerous geologic mission. During the process, they find out far more about their world than they ever wished, and confront the largest mystery of the ages…

What is Equestria?

This takes place, as all of my stories do, in the same universe as Obama Goes to Equestria. Basically, the only context you need to know is that Celestia is evil. Everything else should stand fine on its own.

Written for this.
