The voice of the goddess

The voice of the goddess was going to be a quest in Van Buren, the canceled Fallout 3 by Black Isle Studios.

Walkthrough
The goddess of the Twin Mothers has stopped speaking to her tribe. No one understands why. This is a long and involved quest that leads to the Nursery. The player can choose to help the tribe by simply taking on this quest. The Twin Mothers will not ask for help, in fact they will refuse it. The player will need to initiate this quest on his own.
