Ages Of the Federation is a new series of total conversions to Sins Of A Solar Empire: Rebellion starting with "The Four Years War". The first mod in the series takes place between the Enterprise and Original series eras, focusing on the conflict between the early Federation and Klingon Empire. A Resurgent Romulan Star Empire, angry and still licking its wounds after its defeat to the federations waits in the shadows, ready to take advantage of a misstep by either the warring powers.
"One day soon, man is going to be able to harness incredible energies, maybe even the atom... energies that could ultimately hurl us to other worlds in... in some sort of spaceship. And the men that reach out into space will be able to find ways to feed the hungry millions of the world and to cure their diseases. They will be able to find a way to give each man hope and a common future. And those are the days worth living for."
