A/N: Brothers and Sisters. This story is another plot bunny that refused to leave me alone unless I commit it to paper. It is an antithesis of sort to Battle Brother Potter and I will try my best to update all my stories at a reasonable pace.

Now enjoy and tell me what you think.

Dark Apostle Potter

Prologue

Basilica of Torment, Sicarius, Eye of Terror

It always hurts to be in the Basilica of Torment. The one within, those who are punished by failure to the Legion and Chaos, face eternal torment by daemons of the Warp, where their souls are flayed apart slowly, excruciate them on a spiritual as well as a physical and mental level, only to be recombine crudely, abruptly so that the process can begin anew. For those who are consigned to this hellish construct multiple times, the torment from the previous stays are repeated with greater intensity and viciousness. On the Daemon World of Sicarius, home to the Word Bearer Legion of Chaos Space Marine, multiple failures to the Primordial Truth is not punished by death, but much, much worse.

"Wake up! Eliphas! Wake up, my Brother!" The voice was smooth and resonant. Its owner, however, is a giant being, with a face scarred by millennia of holy war against the enemy of Chaos. He is clad in an ornate suit of terminator armor, an ancestral suit that is passed down from its previous owner to him, from one Dark Apostle to another.

The prisoner opened his eyes to look upon the Dark Apostle, his brother, and smiled.

"Marduk. How nice of you to come and see me. Why so early this time?" Eliphas the Inheritor, former Dark Apostle of the 48th Host of the Word Bearer legion, asked casually. His arms flexing idly against the warp chains that is hanging him. Oh how he long to get out of this place, where he can resume his service to the Primordial Truth.

"Order from lord Erebus himself. He needs to see you." Marduk answered.

"If lord Erebus is so intent on seeing me, why not come down here himself? " Eliphas jeered.

"Watch your tongue, Eliphas! Just because you are my blood brother does not mean that I won't punish you. You are coming, whether you want it or not." Marduk replied. With a wave of his gauntleted hand, the spectral barrier of the cell lowered along with the chains holding Eliphas.

"No chain?" Eliphas asked as he followed Marduk.

"No, not the ones you can see." Marduk replied. Two hulking terminator appeared, flanking both of them as they exit the cell block. Eliphas recognized them as members of the cult of the Anointed, Marduk's Elite Terminator Unit. Each a warrior without peers, wearing massive Tactical Dreadnought Armor, each sport a chainfist and storm bolter, all pointed at Eliphas' back.

After a long walk, they arrived at an old, run down temple, one amongst billions that is built and destroyed daily on the Daemon World of Sicarius. Marduk pointed Eliphas at the entrance, a crumbling doorway leading to the darkness of the temple's interior.

"Go in, brother. Lord Erebus awaits you inside." Marduk gestured towards the door. Eliphas entered, his steps firm and sure for someone who just got out of the Basilica of Torment.

The temple's interior is pitch black, enshrouded in a darkness that even his enhanced senses as an Astartes is unable to help him navigate. Instead, Eliphas relied on his faith alone to guide him forward, further into the darkness.

Suddenly, a large psychic pressure assail the former Dark Apostle in droves, pressing on him on all sides. Eliphas braced himself, using his senses to locate the source of the assault. Then, four pillars of light pierced through the darkness , around Eliphas, each a different colors, Blue, Red, Green and Pink. As Eliphas looked up, he can now see that four dais had appeared in the middle of each light pillar. On each dais stood a figure, all looking at him.

"Inheritor." The voice in front of him intoned, his voice a mixture of a thousand other voices. "You have failed us. Yet again." Eliphas looked up to see an avian face leering at him, its beak razor sharp, and its eyes blazing with sorcerous light. It was garbed in a long, flowing wizard robes and holding a bird-head staff.

"BY ALL RIGHT WE SHOULD JUST LEFT YOUR PITIFUL SOUL TO BE TORMENTED FOR ETERNITY!" came the voice on Eliphas' right, a booming bellow of extreme aggression. Its owner is a bull-headed being clad in bloody brass armor, hefting an immense battle-axe. Its armor is decorated with skull of various shapes and sizes, from human to various species of xenos.

"But an opportunity arise that may yet redeem you, my son." came the gurgle from the fallen warrior-priest's left. The bloated, decaying owner of the gurgle is sickly pale, with mucus and pus leaking from all over its body. While horrific to behold, this figure seems almost fatherly in appearance and demeanor.

"But do not be complacent, Eliphas-dear. If you fail again, your reward will be most … exquisite." Giggled the voice from behind Eliphas. The former Dark Apostle turned around, facing an androgynous figure in bright pink armor with colorful, garish decoration adorned in every aspect of his war-plate. The sheer silhouette of this being would drive lesser beings mad with desire with one look. However, Eliphas' mind was made of much stronger stuff than that.

After all four figures have made their presence known to the former Dark apostle, Eliphas kneeled down, his voice awed and eager.

"My divine masters, please give me this opportunity to redeem myself of my past failures, tell me of this mission that you would have me complete."

"Very well." The bird-like sorcerer intoned. "Tell me, Inheritor, do you believe there is other universe beside this wretched one?"

"Forgive my ignorance, my lords, but I am not aware there is such things as another universe." Eliphas replied, genuinely surprised that the Chaos Gods themselves have decided to share this knowledge with a disgraced servant like him.

"Do not presume this to be a sign of trust, disgraced one." The androgynous being snapped. "We only tell you this because you need to know it for your mission. As I say before, fail and you would be wishing for the Basilica instead of what we have in store for you."

"Yes, my lords."

"The warp, in all of its glory, is a vast hub of passageways. Always changing, always intertwined. Mortals think of it as a shortcut to move across their cosmos." The bloated one gurlgled, its voice fatherly and patient, like a parents explaining basic facts of the world to a toddler.

"BUT HOW LITTLE THEY KNOW! IT IS ALSO A HUB FOR DIFFERENT UNIVERSES TO MEET!" the brass-armored warlord boomed.

"These universes, however, are not yet opened their eyes to the Primordial Truth, our truth." Continued the bird-like sorcerer. "Your mission, should you choose to accept it, Is to train the First Apostle of one such world and prepare him to be the one who will spearhead the spread of our faith in that universe."

"How will I find this Apostle, my divine masters?" Eliphas asked, head still bowed.

"Oh, we have already find the little one." The androgynous being said with a giggle. "You just have to take him and train him." As he said, an image flashed up in front of Eliphas, not unlike an elaborate hololithic projector. He sees a series of houses, each identical to one another, giving it an awfully quaint and monotonous looks. The vision then focuses itself into the front of a house that bears the number 4 on its address plate. There in the front porch, a small basket lays.

"A baby? You want me to take care and train that baby?" Eliphas mentally yelled.

"As a matter of fact. Yes, yes we do." The sorcerer quipped.

"You are going to be a very good father to him, we just know it." The bloated one said affably, its large mouth opened up into a wide, toothy grin, with drools and pus leaking out copiously.

"Please, let this be a cruel jest." Eliphas pleaded as his predicament became clear. "I am a Dark Apostle, a preacher of the Primordial Faith; I can turn planets and systems against the Imperium and into our folds. Please do not make me a nursemaid to a baby! " the fallen warrior –priest pleaded.

"YOUR RESUME IS IMPRESSIVE INDEED, INHERITOR! THAT IS EXACTLY WHY WE WANT YOU FOR THIS MISSION." The brass-armored one bellowed.

"He will need an army, a host of his own." The bird-like one continued"And we will help him build one. But teaching him to command it will be your job, Eliphas. Do this right and your rewards would be great, inheritor."

"Do you accept?" All four then asked.

Eliphas looked up and smirked.

Number 4 Privet Drive, Little Whinging, Surrey, United Kingdom.

"They can't just dropped this little freak at our house!" Vernon Dursley bellowed at his wife, who is looking at the basket on their front porch with a mixture of fear and disgust.

"They could be watching, Vernon." Petunia Dursley said, hesitating to touch the infant in the basket.

"I will not have this freak of nature foul up our perfectly normal home." Her husband jabbed a finger towards the tiny bundle. "I say we dump him into the nearest landfill. If he die, the other freaks will stop looking right?"

"I don't know, Vernon. He is still my nephew. I don't think…." Petunia's hesitated.

Suddenly, a flash of blood red light caught the couple's attention.

On the pavement in front of number 4 Privet Drive, a tall, broad figure appeared. Dressed in a fine business suit of great quality, the newcomer casually opened the front gate of number 4 and approached the gawking couple.

"It seems that you really want to be rid of this baby." The stranger said. It was a statement, not a question.

"That's none of your bloody business!" Vernon bellowed threateningly.

"Fortunately for you, I can help you with that." The stranger stated, his voice low and sibilant.

"Really?" Petunia asked.

"You are not going to believe this freak are you? I say we do it by ourselves. As for you, leave or I will call the bobby on you." Vernon yelled.

The stranger smirked, his face take on a predatory glint in the early morning gloom.

"Unfortunately for you, I will help you with that, whether you want it or not."

What happened next was done in three heartbeats, unseen, unheard by anybody.

The last thing Vernon Dursley see is the stranger's hand reaching for his face before his head was crushed by a squeeze, showering his wife with gore and brain-matter. Petunia opened her mouth, but before a scream could come out, her head was separated from her body by a neat hand chop. The stranger then picked up the basket containing the baby we was sent to retrieve.

The baby is a boy of a year old, with bright green eyes and jet black hair. Throughout the short bloodbath, he stays quiet despite some blood have stained the blanket covering him. The stranger picked up the letter underneath the tiny blanket.

"Harry Potter? Such an ordinary name. No, that will not do at all. By the will of the Gods, I now rename you Harrogath, my child. A great destiny awaits you, my son." Eliphas the Inheritor said to his new-found son.

Then he heard crying coming from the house. "Oh, the other baby. Might as well." The warrior-priest of Chaos remarked. Still holding the basket, he walked into the house and located the source of the crying, a chubby baby in a colorful crib. Scooping up the second baby, Eliphas' face stretched into a grin.

"You know what? I think my son will need a Coryphaus that he can trust.".

Another flash of blood red light and he was gone, leaving behind two bodies and an empty house.
