History:
A mysterious vessel that attacked Enterprise in 2151, forcing Archer to attempt to escape back to Jupiter. The hostile aliens stalked the Enterprise, continuing their stealth attacks and refusing to respond to hails. As the starship fled home, Tucker and Reed installed new phase cannons to provide some kind of defense. The alien ship was shaped rather like a giant insect with green glowing power nascelles. It was heavily armed and shielded and easily outclassed the Starfleet vessel.
