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.

For a thousand years, the Code of Harmony has ruled Equestria, and the Code of Dissonance has sabotaged its works at every turn. Now the war for control over the land will come to a head, and one unicorn's decision may decide the fate of all.

For though she does not know it, Twilight Sparkle is the shining example of the Code of Harmony. Her teacher, Princess Celestia is Harmony's most powerful master and she knows her enemies are hatching a plan that threatens to cast down the Harmony of her throne and all she has sacrificed to create.

What she does not know is her foe seeks a new Apprentice to turn to his dark ways. A unicorn with seemingly limitless potential for magic, whose thirst for knowledge may yet lead her down a dark path, who is known to be such a faithful student of magic, eagerly seeking the truth no matter how forbidden it might be...

Sequel: Code of Harmony

A week away from finals, Jeremy falls asleep at the wheel and has what should have been a fatal accident. He discovers that he is one of a very small percentage of sentients in the universe. He is an immortal. He cannot die. As he struggles to accept his new place in the universe, he must figure out how he's going to begin his immortality... And where he'll go to spend it.

Note: This is a HiE story which spends much more time on characterization of the human. This will not be a 'brony in Equestria' story; it's a chance to explore fictional worlds through a very unique viewpoint.

Daring Do cannot believe her luck when she is asked to help explore the most ancient tomb known to ponykind. But terrible danger awaits her, for beneath the earth rests something beyond equine understanding.

When the princesses receive word of a mysterious illness breaking out at an archaeological survey site in the Badlands, they send Twilight, Spike, and Starlight to investigate. They find a bizarre sequence of markers, signs, and hints left long before pony civilisation as they know it, leading the way to place long forgotten by history. Together, the ponies must uncover their meaning, before an ancient evil from a past not even remembered by ponies leaves its mark on the future.
