This story is a sequel to The God Empress of Ponykind

One thousand years ago, Luna, Warmistress of Equestria and sister of Empress Celestia, fell to the powers of Chaos and plunged Equestria into a brutal civil war. The Traitors were defeated, but not before Luna made the ultimate sacrifice and was sealed away in the Immaterium with only the soul of a slain Primarch to keep her company. For a millennium she has been locked away, waiting for a chance to return to her home and her sister.

Now, she has been freed from the Immaterium, and as she takes her first steps in a new Equestria, one ruled by the powers of Harmony, only one question remains:

Does Equestria still need the services of a Warmistress?

When Spike asked Twilight to help him create The Noble Dragon Code, he hoped a lot of things would happen.

Princess Celestia: Goddess of the Sun, ruler of Equestria, beloved Princess of ponies. She is loved by all, and loves all in return. A calm and wise ruler, she sits on the throne in Canterlot, maintaining peace and harmony throughout the land.

What most don't know is that her past is much darker: She was once a commander of legions, a warrior and scientist of unmatched skill. Thousands of monsters and abominations fell to her forces, slain in the name of an old leader, one entombed within his own throne. Free of her old form, free of the powers of Chaos, she was cast into a new realm, in a new form, with a new lease on life.

She is the God Emperor, Eternal Ruler of Equestria and Lord of the Imperium of Man.

Twilight isn't having a very good day. An experimental spell blew up in her face, an army of changelings is attacking Canterlot, and she just died. Yet somehow, it looks like it's going to keep going downhill from here.

Given the chance to correct what's gone wrong, Twilight swears she's going to fix all this even if it kills her. Which it will. Frequently.

When Celestia went on sabbatical into the west, she promised Twilight it would be only a couple of months. A year and a half later, the sun resists control, the country is in ruins, and her teacher is lost in the wilds. Twilight has become the apostate, her faith in her teacher and her teachings waning. In the wake of tragedy, her resentment blossoms into fury and she vows that something must be done. Shadows gather around Canterlot, and old things that should not have been awakened are on the move. The Student goes west, her hope restored by friendship and righteous fury.

The night, at long last, is passing.

The Death Korps of Krieg, seeking atonement from their government's betrayal decades ago, they give their lives willingly in the everlasting fight against the enemies of the Imperium of Man. Averted by even their fellow Guard regiments, they show a high degree of fatalism and an unusual morbidity of habit. Yet they are highly disciplined, morally reliable and self-sufficient soldiers.

The 42nd Siege Regiment had been deployed on Kheltan III to reclaim a supply route that had been attacked by the Eldar. A simple enough task for the stoic men of Krieg. But an ion storm attack and an innocent experiment by an alicorn from another world can make even the easiest of tasks much more difficult.
