Our Final Acts (Part 3)
Amber Five is a parallel version of Earth, enclosed within its own local shield in a fashion similar to The First World. It was one of a number of Branch Worlds grown in the creation of the Inner Shield and Outer Shield mechanisms by the inhabitants of The First World and the Brownshirts.
The shield of Amber Five suffered a partial failure due to the compression of The Crushing Fist, resulting in leaking radio and television transmissions originating from within the shield. Alek and a volunteer detachment traveled to Amber Five via Earth 44, but found that the Mictlan and other dangerous entities had already arrived and devastated the local population.
