“Loyalty first. Obedience second. Excellence always. This is not a creed. It is the cost of survival.”

She has led humanity’s armies since the day they stepped onto Echelon Prime—399 years ago.

She is the Supreme Commander of the Prime Defense Corps. The blade drawn in defense of the Pact. The Immortal Shield behind which the rest of the system dares to breathe.

There are stories—eyewitness accounts—of her death. Cut down in the breach of a riot fortress. Burned alive in the voidstorms of Specter’s orbit. Crushed beneath the wreckage of a fallen dreadnought. But every time, she returns. Unchanged. Unyielding. Her armor polished, her eyes colder, her purpose sharpened like a blade pulled from flame.

She demands loyalty first, obedience second, and excellence without compromise. These are not ideals—they are mantras. Engraved into every PDC outpost, whispered in every barracks. A soldier does not rise through the ranks without proving, again and again, that they are worthy of serving her cause.

That cause is the survival of humanity. And she has never once doubted what it will cost.

Tatsuken Academy, the crucible she founded in the early decades of the Pact, is more than a military school. It is a sacred forge, a place of transformation. The best officers in the solar system are not trained there—they are remade. They are taught not only how to fight, but how to believe. That sacrifice is honor. That death is a tool. That the enemies of the Pact do not deserve mercy.

She does not speak often, and never speaks lightly. When she arrives on the front, victory follows. When she visits the Academy, cadets weep in silence. When she returns from death, her fire burns brighter than ever.

And if you are lucky enough to serve beneath her,

you do not question where she came from.

You just pray to follow.
