Four Powers War: Klink, Kzin, Lyran, Hyrdan.
Prelude to the General War found here:

The last of the small regional wars involved the Klingons and Lyrans against their enemies, the Kzintis and Hydrans, from Y158 to Y162. The war was savage (being the first to have large numbers of ships involved) but ultimately just another border war as the state of logistics made any deep strikes into enemy territory impossible to support. The logistical systems that would allow such deep attacks were developed in the last days of the Four Powers War, and were perfected in time for the next one.
The Four Powers War was significant, however, for a radical technological innovation (previously known only to the Hydrans) that changed the galaxy forever: warp engines small enough to power armed shuttles. These rapidly evolved into "fighters" which dominated war for the next two decades. Coupled with the new faster drones, war was about to become more affordable and dangerous.
My guess would be that this would mean that the server would be in early the whole time, but I like early era. Perhaps just a short server, and the best thing is no feds (hurray!) and no plasma (hurray!). What say you??
