Grand War

"'All cruisers target that enemy warship!!' Republic admiral Jos Ackbar during the defense of Coruscant against the Khoan Invaders. " The Grand War, also known as the War to end all wars, was a conflict that occurred following the end of the Eternal Empire. The galaxy weakened by centuries of warfare, was ripe for a invasion by the Immortal (Khoan) Empire. Emperor Mattock-Ko launched a massive invasion force attacking key stat systems, and raiding several worlds whose governments have collapsed from tributes to their respective fractions. They also targeted and razed bread basket planets starving millions of people across the galaxy.

The Khoans lockdown conquered worlds, and deployed slave soldiers to keep order. They also forced their slaves to construct war machines, siege engines, warships, temples, and serve as living sacrifices to their dark gods. The Khoan committed numerous atrocities from inhumane experimentation on a planets native population and ecosystem, to destroying a shuttle carrying children.
