In the Battle of Doliin Bay, a pair of UPF Ships — the frigate Z'Gata and the assault scout Stiletto — were dispatched to guard the small space station Doliin Bay, in orbit around the planet Ken'zah-Kit. In the second week of this routine duty, the Doliin Bay's powerful sensors detected a pair of ships entering the system from the Void. As they streaked closer, the computer sketched the sleek outlines of a Sathar heavy cruiser (The Perdition) and its destroyer escort (The Venomous). The UPF crews, facing a far stronger enemy, realized they had to flee, but they could not leave the Doliin Bay garrison defenseless against the invaders!
