On the grounds of the Taros Iceworks, explosions of the Warp erupted every second that passed. Far off, a drop pod touched down, and Hammerheart and the Blood Phoenixes came out.
"Ah! You finally show your faces." Aroghent said, still mocking them through their channel. "Have you mastered your fear at last?"
"We know no fear!" said Applejack.
The Pony Marines went out in search for the boastful heretic. The Iceworks were succumbing to damage from previous dimensional rifts of the Warp, but still seemed stable for now.
"You Blood Phoenixes are clearly 'fearless' in your hurry to leave the sector." Aroghent yelled. "The courage with which you show us your hind quarters does your Empress proud."
"Turncoat scum!" said Hoovitus. "I will kill you here and now!"
The Pony Marines marched up a flight of stairs and reached a giant ventilator system that still functioned despite countless years of neglect.
"Very impressive." Aroghent sarcasm was clear as he approached them from the other side. "You have more steel than the rest of your Chapter." He stopped dead center over the big vent. "Rejoice, siblings. Your slavery to the False Empress ends today."
Applejack leered. "The only thing ending today is your worthless life." She said.
"Yes! And to the void with orders and niceties!" said Aroghent. "But not quite yet, little Blood Phoenixes. First a test. Make your way to my chosen battleground." Aroghent conjured a Warp shield as the Pony Marines opened fire at him. "Skarsend! Open the portal!"
"Yes, Lord." said Skarsend.
Within a flash, Aroghent was gone, teleported to the place he wished to fight the Blood Phoenixes.
Meanwhile, the Pony Marines had to search for Aroghent again, pushing through Discord war bands that stood in their way.
"Marvelous!" Aroghent shouted, implying the Blood Phoenixes reached him. "I will remember you fondly when I burn your worlds to ash!"
Hammerheart, Goliath, and Rainbow Dash went in to engage in melee. Twilight, Applejack, Pinkie, and Hoovitus fired away at the heretic. Aroghent proved to be a challenging force, even against a Harmonaught like Goliath. He could take some serious hit, yet he still held his own. But just because he was strong doesn't mean he was invulnerable.
"Glorious!" Aroghent yelled, "Lord Khorne smiles on us, Blood Phoenixes! Do you have the will to pass this final test?" He stepped back while the Pony Marines continued to shoot. "Skarsend! The next portal."
"Yes, Lord." said Skarsend.
Again, Aroghent disappeared in a bolt of Warp energies and reappeared elsewhere. He began sacrificing cultists to heal himself.
"Coward!!" Hoovitus shouted, "You will not escape!"
The icy cliffs nearby where the Pony Marines were began to crumble and fall apart. A large piece of the ledge managed to jam itself between the cliff it was a part of and the ground beneath.
"Commander, look! A way forward." Pinkie said, pointing to the makeshift ice bridge. "We can finish this yet."
They headed to the bridge, but more cultists blocked their path. Applejack threw a grenade that exploded and sent them flying off the cliff. They moved on, and Applejack spotted something in the distance.
"There is a shrine ahead." She said. "It is sure to be well defended, but securing it would aid us greatly."
They approached the shrine and attacked the Discord Marines garrisoned inside. The heretics fought back, but were overwhelmed by the Blood Phoenixes' strength in numbers.
"Yes! Fight on for the Blood God!" Aroghent shouted.
More Discord war parties came in, and they were just as quickly killed by the Pony Marines. The ice and snow grew redder and redder with every Pony Marine, Celestial and Discord, that fell.
"Observe, Blood Phoenixes!" said Aroghent. "Khorne thanks you for your offerings!"
After securing the shrine, they galloped Empress's speed and found Aroghent once again, fully healed and still standing tall and proud of himself.
"Your running is over, traitor." said Hoovitus. "Now you die."
"Fearsome words, Blood Phoenix." Aroghent said, mocking the Sergeant. "Now show me deeds."
The Pony Marines went in and attacked. Aroghent was still as formidable as before, if not more. Hammerheart swung his Thunder Hammer and slammed the Plunderer with great strength, Rainbow Dash slashed at his armored body with her Power Sword, and Goliath pounded him with his Grappling Limb. From a distance, Twilight blasted him with deadly magic spells, Applejack pumped plasma rounds at him, Pinkie sniped him in all the weak spots of Discord Marine armor, and Hoovitus unleashed hell with his Heavy Bolter.
But Aroghent was still standing, still boasting like the braggart Hammerheart called him. For every grievous wound that he received, a cultist exploded in a bloody mess, and his injuries healed. "See?! Hear is the power you are denied!" He proclaimed. "Who sacrifices for you, Blood Phoenixes? No one! NO ONE!!"
"He feeds on them." Pinkie hissed. "Kill the heretics to weaken him."
Pinkie and her scouts turned their attention to the cultists and began to pick them off. Soon the cultists were all killed, and Aroghent was left without support. The Pony Marines continued to give him the beating of a lifetime, and he knew he was in danger. He stomped the ground, and a wave of Warp energies sent Pony Marines flying, and disabled Goliath's mobility.
"Skarsend!" Aroghent struggled to speak.
"Yes, my... lord?" said Skarsend.
"Open a portal..." said Aroghent.
Skarsend pondered for a bit before he sinisterly replied with, "No. I think not. A change in leadership is in order." Skarsend then laughed at his former lord, and left him for dead.
"Skarsend!" Aroghent called. "You treasonous dog! No!!"
Hoovitus trotted up to the Plunderer. "No escape this time." He upper-cut Aroghent with his gun and unloaded bullets into him. With the final shot, the boastful Discord Lord dropped dead. The other Pony Marines got back up, and Goliath regained his mobility.
Aroghent the Plunderer has fallen.
