Undercity

The An Sinia Undercity is the name for the half-natural, half-manmade cavern city deep within the bluffs overlooking the Toren River. The Undercity contains a wealth of mineral resources and gemstones, but its distance from An Sinia proper leaves it a mostly lawless city of pioneers. The only authority nearly every Undercity resident respects is the ancient Librarian.

History
The Undercity first existed after the great earthquake that tore great cracks in An Sinia sent portions of the city hurtling down into new chasms. The first scavengers and explorers venturing down towards the rubble discovered other caverns that had been laid open by the new canyons, which began to be mapped.

The discovery of silver in the caverns changed everything, and people began to stream down into the caverns, looking to make their fortune. A city was carved into the very rock, and every mage in An Sinia was called to light the caverns with undying torches.

Even though every trace of silver has been exhausted by now, the Undercity still offers a fast route to the river bank, the promise of unexplored territory, and an escape from the authority of An Sinia above. The closer in the Undercity a place is to the canyons leading to the surface, the safer it is as a general rule. The deeper in the black one goes, the more wild it becomes, rivaling some of the eastern mountains as far as murder-over-conversation goes.
