The Protectorate – an interdimensional empire that has conquered five timelines so far – has set its sights on ours. Led by a man willing to risk everything for power and conquest, armed with technology a hundred years ahead of ours – technology promising salvation to its allies and doom to its enemies – and drawing on a far deeper military history, the Protectorate Expeditionary Force has arrived to invade and incorporate our world into the greatest empire the multiverse has ever known, or die trying.

And as the war for the future of our timeline begins, and spreads right across the world, we are forced into a fight we cannot win ...

.... And yet dare not lose.
