Kiva

The Kiva is a pit in Mesa Verde. In 2088, the Mesa Verde computer began to fail. The scientists feared that technology of the "Old World" would be lost forever, so the scientists began to paint and carve electronic schematics into the walls of the Kiva. It is now being used by the Ciphers to teach children maths.

Appearances
The Kiva was going to appear in Van Buren, the canceled Fallout 3 by Black Isle Studios.
