History:
A Large, Silver Octagon, with tall, Boxy Buildings on top and Bottom, the Eta-Class is one of the earlier Giant Space Stations Starfleet has employed, and although the contemporary Theta-Class was more prominent and popular, this station, an occasional servicer and border defense/intelligence station, was quite successful, and the last was retired in 2358.
