Centuries before Valkorion's arrival on Zakuul, the Eternal Fleet was in the process of systematically decimating all life in Wild Space. Legend speaks of a single massive, alien warship that could counter the Fleet's might: the Gravestone. Outfitted with specialized weapons designed to take out multiple targets at once, the Gravestone could destroy entire sections of the Fleet--including capital ships--with a single shot. After the final battle, the Eternal Fleet was deactivated and the Gravestone believed to be lost. Zakuulan archeologists have scoured Wild Space for a trace of the old warship, but so far have been unsuccessful.
