Nobles tower, New Canterlot Hive, New Canterlot XXI
Lady Rarity fussed at the mirror, using a brush to get her luxurious and gorgeous coiffure just right. After all, a mare such as her had to work hard to win the heart of Governor Blueblood.
Rarity stifled a squeal of joy at the thought of her charming prince. Blueblood had been surprisingly charming to her so far, since most ponies chose to avoid her, and not just because she wasn’t a true noblepony.
After all, many ponies were terrified of psykers.
Rarity sighed at the gaping holes where her once beautiful eyes used to sit. Burnt out by the soul binding, all that was left of them was scarred tissue marring her face. Still, her third eye more than made up for their loss, granting her extraordinary psychic powers. Even if they made her face horrifically ugly.
If she still had eyes, she would have closed them as she concentrated, sending out a burst of psychic energy, levitating a fine, silk blindfold over her face, hiding her eyes. She could have done it with her inherent Unicorn magic, but she preferred psychic manipulation. Most Unicorn psykers did, due to the greater power and precision it granted. After all, why wear rhinestones when you could have diamonds?
A quick glance in the mirror at the snow white unicorn within showed her that she was perfect, ready for her meeting with her prince. Technically, he was only the governor of this system, but the archives suggested that Blueblood’s family line could be traced back to the God-Princess herself.
How the Ecclesiarchy hasn’t deemed that heretical is anypony’s guess, she wondered to herself as she walked through the lavish mansion that made up the top most spire of the hive, her staff of office floating alongside her.
Lost in thought, she was surprised to find herself outside of Blueblood’s study. She paused, before shooting a quick glare at the guard stood in front of the door.
The poor colt nearly fell over himself as he turned to announce her presence. “M-my Lordship? The Astropath Rarity is here to see you.”
“Send her in,” was the curt reply. Rarity stepped past the guard without giving him another look and into the room.
Blueblood’s study was extravagantly furnished, with rugs, tapestries, and furniture made from rare White Tail wood. Sat behind a large desk was the stallion in question—tall, strong and with a face that looked like it had been chiseled from marble. Rarity could feel her heart swoon.
“Rarity,” he said, standing up, “you look as dazzling as ever.”
“Oh, my Lord, you flatter me, surely,” Rarity giggled.
“It’s not flattery when it’s the truth,” he said, flashing a smile at her. “But I didn’t call you here just to admire your beauty.”
“Oh, then why did you summon me?” Rarity asked playfully.
Blueblood moved over to a bookcase. “Because I’ve been working on a little project, one which I am hoping someone of your talents can help me with.” He pulled a book of the shelf, causing the whole wall to slide into itself, revealing a secret passage.
“Oh my,” Rarity said, approaching the passage. “Have you been a naughty boy?”
Blueblood grinned at her. “Very.”
The two unicorns grinned and stepped into the corridor together. There were a few twists and turns, but overall it was a short route. At the end of the corridor was a large chamber, shrouded in darkness. Stood in the center of it was a ring of ponies, all wearing robes.
Rarity’s nose wrinkled as a foul stench assaulted her, and her horn tingled from the heavy psychic presence in the room.
“My Lord?” Rarity asked, concern heavy in her voice. “What is this?”
“Let me show you.” Blueblood put a hoof on her withers and pushed her forwards. The circle of ponies parted, admitting Rarity into the center. The foul stench and the tingle in her horn grew stronger.
Rarity opened her third eye fully and cast it about the room, gasping in shock. Located in the center of the circle of ponies was an alter, strange glowing runes upon its sides. And on top of it lay the eviscerated body of a young filly, her now activated witch sight showing her the horrors that had happened during the filly's final moments.
"Blueblood," Rarity said, her eyes fixated in horror upon the corpse. "What is the meaning of this?"
Rarity felt Blueblood’s lips move near her ear, his breath on her neck. "The meaning? Why, for the glory of Slaanesh, of course."
"For the Glory of Slaanesh," droned the amassed ponies.
Rarity flinched as if she had been slapped, the forbidden word an assault upon her very soul. Her horn screamed in protest and blood dripped from her nose.
She turned her head in shock, staring at Blueblood, her witch sight showing him for who he truly was.
An emaciated pony stood before her, cheeks gaunt and stretched in a rictus grin, drool leaking from between crooked teeth. A mad, feverish glow lit up his eyes, giving him a predatory look. He was a perversion of beauty and grace, given mortal form.
Rarity didn't have time to think before she slung a psychic bolt against him, snapping his neck instantly.
Panting, she looked around herself as the remaining cultists stared at her in hate and anger, before advancing on her as one.
"Hail Slaanesh," they chanted as one, ceremonial knives appearing from beneath the folds of their cloaks. "Hail Slaanesh and die."
