The Paulos, a minor race, are being attacked by the arrogant Terran Alliance. Having most of their trade either going to or coming from the Paulos, and not wanting to directly attack the humans, the Covenant send the Paulos 8 fighters and 8 capitol ships, and funds to support their resistance.
Thing is, upon transfer of the ships, which would no doubt turn the tide of war in the Paulos favor, all engines were mysteriously sabotaged and rendered utterly useless. All the transfered ships read 0/9 moves week after week and are unable to leave Covenant territory. Needless to say, with the Covenants military power now cut nearly in half, and the Paulos' reinforcements not able to make it to the battle, the minor race was exterminated and the planet was raped of its resources by the vile Humans.
Nobody knows what caused the mysterious engine failure of the Paulos reinforcements. There are rumors that human spys working within the Covenant government had sabotaged the ships, but leader Rasumee' denys this, saying "The possibility of human spys amoung us is absolute zero. Dont you think a being that hideous would kinda stand out in a crowd of grunts?"
Just thought I'd add a little flavor to it. But yea, this should be looked into by the devs, because it caused the holocaust that was brought upon the poor Paulos.
