The Lost Library of Hyperborea

Swythe surveying the discovery of a lifetime: the long lost Library of Hyperborea

The arctic bunker systems were greatly expanded after The Apocalypse by borerwryms, bioengineered creatures that devoured rock, and were used to create ten thousand miles of interconnected chambers and tunnels that ran beneath the length of North America. 

The Great Library of Hyperborea was lost when the underground civilization collapsed, along with all its knowledge. 

Five hundred years later, a fissure opened up in the earth's crust, shattering the communities on the surface. When the rent in the earth was eventually explored by adventurer Ardwin Swythe and his team of Spelunks, they rediscovered the lost library and a world of knowledge that would ignite a New Enlightenment.
