Adyta Adytum Shrine
An adytum is the innermost sanctuary or shrine in ancient temples, or, by extension, a private chamber or sanctum.
The Adytum, part of the Boneyard, is in Fallout 1, not Fallout 3. It is located in what used to be California, while Fallout 3 is based around the remains of Washington D.C.
