The year is 2409 (STO time) and the galaxy is at war. The needs of the Federation grow every day and therefore new resources are poured into the efforts quite often. One of the resources is a new outpost station, SB Legacy, one of the latest stations in Starfleet. Although based on an older design, it has some of the newest technologies as well as a Saber class escort and other support craft.
