Second Earth

Hundreds of miles beneath Earth's surface is a second world, created by the presence of a bizarre metal whose properties insulate this hidden world from the heat of the inner Earth and forces open a gap in the planet's physical structure. Protected from the hazards of the world above, life forms that find their way down here have evolved in the unique biomes into myriad strange forms. Between the astounding scenery, fascinating creatures, and people of all kinds, the Second Earth is a haven for wonder and adventure.
