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.
2242: USS Xenophon leads a raid on Klingon fortifications far behind enemy lines. The moniker by which Kelvar Garth would become best known, 'Garth of Izar', was first bestowed upon him by the Klingons following his victory at Cygnus III, but it wasn't long before the name spread through the Federation as well. Following Cygnus III, Garth led a highly successful guerilla campaign against the Klingons, frustrating their war effort and straining their supply chains. With each victory his fame grew, spread by a populace in dire need of a hero on which to rest their hopes.
