-The Story

Deep underground lies an immense living facility: Foundation.
When was it built, and why? Who, or what, brought its residents there? The truth has faded with the years, and its history has sunk into the ocean of time. No one within knows of the surface. To the people of Foundation, the underground facility is their entire world.

Then, calamity strikes, changing the fate of five young girls.

Their world is suddenly deserted. Quakes assail the underground halls, walls and ceilings collapse, and food and water begins to run out. Five girls, the final survivors, must find a way to pull through these dire conditions.

Foundation is on the verge of collapse, and the girls face their longest and final trial...
