It orbits a black sun at the edge of the known galaxy in a system whose name has been deleted from every Imperial record. It is a vessel as large as a space hulk crafted from a metal pulled from the Warp itself that is bound to the will and pay signature of the man who brought it into this reality. Its black form is that of the double-headed eagle of the Imperium of Man. The Wrathful Fall orbits the black sun asleep as it has been for over eleven thousand years. Filled with the xeno technology older than mankind and technology that humanity has forgotten how to create, it is a force capable of annihilating fleets and burning star systems to ash. The existence of this vessel and the existence of those aboard it is a secret known only to the Emperor.

Lord Eversight and Dalat step through the dimension of madness known as the Warp, but the beings who call it home, who would usually strip the souls of anyone who steps into their domain, run away shrieking as the pure light of the Emperor's Avatar burns anyone who gets near them to ash. Their ashes are then pulled into him, adding to the power and darkness of the Dreadlock thousands are burned and absorbed in the brief seconds they are there. With a crack of thunder, Eversight and Dalat appear on the darkened bridge of the ancient ship. Sensing the psy signature of its master, the lights come on, and the entirety of the Wrathful Fall comes to life deck by deck. The bridge is a complete circle made of the same black steel as the rest of the ship. It has a single command throne in the center and clear walls that give a 360-degree view of the space around it. There are no stations, screens, or monitors in sight.

"My lord," says Dalat, looking around at the near-empty space, "May I ask where we are?"

Eversight walks forward to the command throne and takes a seat. It senses him, the Dreadlock armor, and the tech locks on the bridge release. Holographic displays appear all around him as the command throne floats into the air. He takes a few moments to glance at each display, taking in the vast amounts of data in seconds. Then he wipes them all away and turns his gaze on Dalat.

"This is the best-kept secret in the Imperium, Dalat," says Eversight, "This is the Wrathful Fall. It is possibly the most powerful vessel in the galaxy. The Emperor himself created it with the help of one other individual."

"Who, my lord," asks Dalat.

"Me," says a soft voice in both their minds.

There is a slight shimmer to Eversight's right, and he raises a hand to stop Dalat from raising his Guardian Spear. As the being fully appears. It stands at an impressive height of around 7 feet, its slender, elongated body covered in iridescent, crystalline scales that shimmer and reflect light. Its skin has a mesmerizing, holographic quality, displaying a constant flow of colors and patterns that seem to shift and change as it moves. Its head is shaped like a delicate, inverted teardrop, with large, black, almond-shaped eyes that seem to absorb and process vast amounts of information. Two thin, almost transparent membranes protrude from its forehead, resembling delicate wings or antennae, which quiver and vibrate as it communicates or senses its surroundings. Its long, spindly limbs end in dexterous, articulated fingers, each tipped with a tiny, glowing node that pulsates with energy. These nodes allow it to manipulate and interact with its environment in subtle, precise ways as if it can tap into the fundamental forces of the universe. A delicate, filigree-like pattern of silver-blue lines adorns its body, pulsating with a soft, ethereal light that seems to be connected to its very life force. When it moves, its body shimmers and ripples like the surface of a pond, as if it is perpetually dancing on the threshold between reality and the unknown. Despite its otherworldly appearance, the exudes an aura of gentle curiosity and wisdom, as if it holds secrets and knowledge beyond human comprehension. Its presence is both captivating and unsettling, inspiring a sense of wonder and trepidation in those who encounter it.

"Hello, my name is Zhra'zhi," says the alien again into their minds, "But you may simply call me Zhi."

"My lord," says Dalat, his tone questioning, "Who and what is this xeno? Why is it here? Wherever here is."

Zhi giggles at the use of the term xeno: "If you want to know about me, Dalat, you can simply ask me. I helped in your creation, too, and I am happy to answer all of your questions."

Dalat bristles at the use of his name and the alien's claim, but before he can say anything, Eversight connects with him mentally and gives him the truth that turns his world upside down and makes him stagger. Well to be more specific, he unlocks the knowledge stored in the minds of every member of his order but is psylocked. The knowledge that Zhi is a member of a race of aliens from another universe called the Psyri. Their race was old when the first sparks of life appeared in this universe. Zhi is an explorer who came here to watch that life grow. She never interfered with it until the day she sensed a life form in this universe with the same level of psychoactive potential as a highborn member of her race like herself. She made contact with the Emperor when he first left Earth, as Terra was known then. They became fast friends, and she was his most unwavering supporter. She had warned him of the possible dangers of his plans, but she always walked with him in the shadows. She gave him the knowledge that increased his own when he created the Custodies. She is the true mother of many of his greatest projects, including the Primarchs. Though she warned him about the risks that would come with their creation and those whom he trusted.

When the Heresy started, and Horus led the Traitor Legions against Terra, Zhi had wanted to bring the Wrathful Fall and its secret and deadly cargo to the aid of the Imperium. This would have drastically changed the final outcome, but the Emperor forbade it. He gave her strict orders to keep to the shadows and complete her half of Project Eversight. Over the last ten thousand years, she has done just that. The flow of information drops Dalat to a knee as he becomes the only being outside of the project's strict circle to ever be granted this information.

"He prepared all of this in case he failed," says Dalat slowly, with his head bowed. He did not even share this with his closest companions."

"He trusted the Custodies completely, Dalat," says Eversight, "Don't doubt that, but this is a plan he trusted no one else with. This ship, the technology, and the force it fountains are not things he trusted anyone with outside himself and, by extension me, with. It is the power to turn this galaxy on its head."

"The force," asks Dalat as he rises to his feet, "What force do you mean?"

"Well, now that secret is connected to another of the Imperium's greatest secrets," says Eversight, nodding to Zhi. You, of course, know about the Second and Eleventh Legions, or the Lost Legions, or at least the information the Emperor allowed you to retain after the Edict of Obliteration."

Dalat nods his head slowly. This is a subject that is not spoken of even within the ranks of the Ten Thousand. The two Primarchs and their legions were destroyed for the Horus Heresy ever began. They had their names, histories, and deeds obliterated from all Imperial records to the point where no one knows that there were twenty founding legions, not eighteen. The stories of their falls are tragedies that have been purposefully lost to time. The two Primarchs were indeed killed long ago by the hands of the Emperor himself. But their sons simply disappeared. Many believed they were quietly absorbed in the ranks of the Ultramarines, and this is partly true. All of those who were not selected for a special project were given to the Ultramarines, but that was only a little over fifty thousand from a combined force of over a hundred thousand. The Emperor then ordered Roboute Guilliman, Primarch of the Ultramarines, to report greater numbers than he actually had. Those chosen for the project were placed in stasis and given over to Zhi's care. Over the last ten thousand years, she has changed and enhanced their bodies, minds, and armaments to make them into a force like no other. Zhi raises a thin, long-fingered hand, and it glows. More shimmers appear that quickly solidify. Ten Space Marines clad in advanced silver, black, and gold armor that looks like the power armor of a Space Marine excepted sleeker, with the roaring skull head of an ancient, red-eyed lion on their chests, appear.

"Meet the Dreadmarines," says Eversight as he rises, and the Space Marines all fall to one knee. They are my legion, and like me, each of them possesses a dual nature. They are hybrids; each has the powers of psykers and souls of Blanks. It is a combination of natures that should be impossible, but one Zhi has perfected in order to create over fifty thousand of their kind. Combined with the bodies of the new generation of Space Marines, armed and armored with weapons and gear that she has created by combining technology she has gathered and reverse-engineered from her people's technology as well as that from other races, alive and dead. She has made a legion like no other. One that has slept for over ten thousand years.

"Psyker and Pariah," says Dalat in awe and disbelief, "That isn't possible. How can they call on the power of the Warp if they can't touch it?"

"They do not use the power of the Warp," says Zhi, "Their powers are fueled by their souls, much like the powers my people wield. Each of them has a shard of the Emperor's flame inside them. They, like Lord Eversight, are an extension of his will and wrath."

"Now, it is time for that wrath to be felt," says Eversight with a smile, "Dread Supreme Xal Rubros, are you and your brothers ready to serve?"

Xal raises his head, and his lenses meet Eversight's, "We are ready for any war and every enemy. We will teach them dread."
