This mod adds Fallen Empire unique buildings and ships.
A number of Fallen Empire tier technologies are included, such as the Class-4 Singularity, Sky Dome, Aegis facility, Escorts, and Battlecruisers.

The test play has been completed to some extent, but I would be happy if you could report any problems.

A new origin is also added: “Ancient Production Base”
Empires that take this origin start on a completed Ringworld with their capital is filled with Fallen Empire buildings.
Furthermore, you will start with the Fallen Empire related technologies added with this mod already researched.
