Star-Wars-Gravestone

The Gravestone was a combat frigate built by a group of scientists in the planet of Iokath,[9] centuries before the Galactic War between the reconstituted Sith Empire and the Galactic Republic.[5] The Gravestone's powerful Omnicannon was capable of targeting an enemy starship and spreading the damage to other nearby vessels, which proved incredibly useful against the Eternal Fleet[5]—a massive fleet of unstoppable warships controlled by sentient droids that was decimating all life it encountered. In a massive battle, the Gravestone defeated the Eternal Fleet and deactivated it, leaving the ships dormant somewhere in Wild Space.[10] The Gravestone was believed lost, though in actuality its builders scuttled the frigate and set it down in the Endless Swamp of the planet Zakuul, where it remained for centuries.
