Mine of Torments

From the back of the book:

The vast Deltan mountain range in the ancient world of Skyfall is the domain of the legendary Dwarves. For centuries they have tunnelled in search of Mithral, magical metal of the Gods - until d demonic power drove them from their mine.
Now some spectral fiend stalks the underground galleries, and conjures up sudden blizzards, rockfalls and floods in the face of any who dare approach the place.
Yet a fortune in precious ore awaits a bold adventurer like yourself...
Prepare to confront the grisly horrors that haunt these frozen crags - and finally enter the terrible Mine of Torments itself - in this Advanced Fantasy Gamebook!
