Short Version:

Cyrus Redmond was 'rescued' from a war-torn Earth, after Imperial forces launched an assault on the monster-riddled planet. Forced from his home, he has been conscripted into the Seventh Inquisitional Force, which is now gearing up to enter a war unlike any humanity has ever faced.

Long Version:

Hundreds of years ago, Earth experienced a war unlike any other. Monsters, ranging from giant, slobbering Gruks, to the deadly, knife-eared Ki'tar, had appeared across the globe, slaughtering countless civilians. With each passing day, more deadly monsters appeared, chasing those few humans that managed to fight back through magical portals that had formed, a gift from what passed as Gods in the twisted reality humanity had found itself in.

The survivors arrived on an alien world, just as hostile, if less chaotic, than the one they had barely escaped. Scattered, divided, leaderless, humanity struggled for nearly a hundred years to cleanse the planet of alien scum. The Empress, long may she reign, led a great swath of humanity throughout the crisis, and took hold of her unquestionable right to reign supreme over all of humanity, now known as the Exsilium Imperialus, the Empire in Exile.

Six hundred years had passed since the great Ascendance, as called by the many aliens that had invaded Earth, and the Empress still rules atop her throne. Humanity had long since expanded beyond its new home, invading dozens of similar planets through the complex Wyrdways that bridged between planets. They conquered and Enlightened many burgeoning civilizations, and even a few exiles that had met a similar fate to humanity's own. With the combined power of dozens of planets, the Empire flourished.

Years of research had allowed humanity to harness the Wyrdways, achieving instantaneous travel to various worlds, but never could they find a way back to Earth, the Holy Homeworld of the Empress in Exile. That was, until now. After six hundred years of constant struggle, the Royal Sorcerors had finally managed to open up a hole back to their beloved world.

The Empress led an assault upon the monster-infested world, but was sorely defeated, their foes having long-since entrenched themselves on the planet. Great magical fortifications blocked their attack, leading millions of humans to their deaths. The forces of humanity retreated back through the Wyrdways, but not without plenty of spoils. Powerful magics, old relics, and, of course, the remnants of humanity that had survived. Cyrus was one such man, having been raised in safety and luxury, despite the cruelty of the world outside his home. Now, he has been ripped from his home and family, and placed within the Seventh Inquisitional Force, which quickly began mobilizing for yet another war.

Determined to show the might of the Empire, and quell any thoughts of humanity's possible weakness, the Empress has ordered that her remaining forces enter a battle that the humanity has not seen in nearly six centuries. They will vie for dominion over a Homeworld, one that, at this very moment, is in the process of Ascendance, like earth had experienced, many hundreds of years ago. Riches await those who succeed. To those who fail, only death and shame await.

For the glory of the Empress, long may she reign!
