Greg the diamond Authority

The morning sun over Beach City usually felt like a warm invitation, a gentle nudge to get the day started with a cup of coffee and a tune on the guitar. For Greg Universe, waking up in the back of his van was a ritual of comfort. He sat up, his back popping in three different places, and reached for the small mirror clipped to the sun visor to check if his hair had migrated into a bird’s nest overnight.

He froze.

"What in the...?"

Greg leaned in closer, his nose nearly touching the glass. His eyes, usually a soft, approachable brown, were different. The pupils had narrowed and sharpened, turning into distinct, hard-edged diamonds. But they weren't the pink of Rose’s or the yellow of the Great Diamond Authority. They were a deep, electric shade of lavender.

"Is this a light thing?" he muttered, rubbing his eyes vigorously. "Maybe I ate some bad leftovers from the Big Donut."

He looked again. The purple diamonds remained, glowing with a faint, inner luminescence that made his skin crawl with a mix of awe and terror. He felt a strange heat radiating from his left forearm, a pulsing sensation that felt like a second heartbeat.

Before he could process the panic rising in his chest, the sliding door of the van creaked open.

"Dad? You awake? I brought breakfast and—"

Steven stopped mid-sentence. Standing beside him was a Gem Greg had never seen before. She was tall and slender, her skin a pale mauve, dressed in a sheer, flowing tunic that shimmered like silk. Her hair was styled in two elegant loops that resembled a regal headpiece.

The moment the Pearl’s eyes landed on Greg, she let out a gasp that sounded like a chime. She didn't just look at him; she looked *through* him, her eyes wide with a devotion that bordered on religious fervor.

"My Diamond," she whispered, her voice trembling.

Greg stumbled back, tripping over a stray guitar pedal. "Whoa, hey! Who’s 'Diamond'? I’m just Greg. Just plain old Greg."

The Pearl didn't listen. With a grace that made the Crystal Gems look clunky, she snapped her heels together and crossed her arms over her chest, forming a diamond shape with her hands—the salute Steven had described after his harrowing trips to Homeworld.

"You have returned," she said, her voice thick with emotion. "The stars have been dim without your radiance, Purple Diamond."

Steven dropped the bag of donuts. "Dad... your eyes. And... what is that on your arm?"

Greg looked down, finally pulling back his sleeve. Embedded into the skin of his forearm, just above the wrist, was a gemstone. It was a perfect, multifaceted diamond, glowing with the same lavender light as his eyes. It didn't look like it had been stuck there; it looked like it had grown from his very bone.

"Steven, I don't know what's happening," Greg said, his voice cracking. "I just woke up like this! I’m not a Diamond, I’m a roadie! I’m a car wash owner!"

"We need to get to the house," Steven said, his face pale. He grabbed Greg’s hand, his own hybrid strength pulling his father out of the van. "Garnet will know. She has to know."

The Lavender Pearl followed them, hovering inches off the ground, her eyes never leaving Greg. "Please, my Pearl-less Master, do not exert yourself. The journey has been so long."

They sprinted across the sand, the Pearl gliding effortlessly behind them like a ghost of a forgotten era. When they burst into the beach house, the Gems were already there, sensing the shift in the atmosphere. Pearl dropped the tea kettle she was holding, the ceramic shattering against the floor, while Amethyst nearly choked on a piece of plastic she was chewing.

Garnet stood perfectly still, her three eyes wide behind her visor.

"Garnet! Look at Dad!" Steven shouted, gesturing wildly.

Garnet stepped forward, her hands trembling—a rare sight for the fusion. She took Greg’s arm, inspecting the lavender gem embedded in his flesh. She stood in silence for a long moment, her Future Vision clearly working overtime, weaving through threads of a history that had been erased from every star chart.

"It’s true," Garnet whispered. "The legends of the Fifth... the one who walked away before the war even began."

"Garnet, talk to me," Greg pleaded. "Am I dying? Is this some kind of weird Gem flu?"

"No, Greg," Garnet said, looking him in the eye. "You are a hybrid, just like Steven. But your lineage isn't from the Earth or the Rebellion. You are the last descendant of the Purple Diamond—the royal who abdicated the throne and chose to live among the organic life of a distant system long before Homeworld turned its sights on Earth."

"A Diamond?" Pearl gasped, clutching her throat. "But that’s impossible! The records were scrubbed!"

"Because she wanted to be forgotten," Garnet explained. "The Purple Diamond line valued freedom over dominion. It seems that essence stayed dormant in your family line, Greg, passing through generations until it finally manifested in you. You aren't just a human who fell in love with a Diamond. You are a Diamond Royal yourself."

Greg sat down heavily on the sofa, his head spinning. "I just wanted to play the guitar and wash vans. I don't want to be a royal anything."

The Lavender Pearl stepped forward, kneeling at Greg’s feet. "My Diamond, you cannot deny your brilliance. The era of hiding is over. Homeworld languishes without your specific frequency of wisdom. You must be restored."

Before Greg could protest, the Pearl reached out and took his hand. Her touch felt like a jolt of electricity. "We must prepare you. You cannot face the galaxy in... these rags."

"Wait, wait!" Steven cried out, reaching for his father.

But the Pearl was faster. With a burst of lavender light, she initiated a warp. Greg felt his molecules stretch and pull, the familiar blue light of the warp pad replaced by a violent, regal purple.

"Dad!" Steven’s voice echoed as the beach house vanished.

***

Deep within the subconscious realm of the Pink Diamond gemstone—the core of Steven’s being—a presence stirred.

Pink Diamond sat in a void of shimmering light, a place where memories and echoes resided. She had been quiet for a long time, watching Steven grow, watching Greg live his life. She had loved Greg for his simplicity, for his humanity, for the fact that he was so utterly *not* a Diamond.

But now, as she watched the lavender light fade from Steven’s vision, a cold, sharp feeling pierced through her. It was jealousy—a jagged, ancient emotion she thought she had outgrown.

"Greg?" she whispered to the empty void.

The realization hit her like a physical blow. Greg wasn't just her favorite human. He was one of *them*. He was a peer. And now, some random, nameless Pearl was whisking him away to a throne he never asked for, taking him to a world where she could no longer reach him.

Her eyes flashed with a dangerous, pink hue. The walls of the inner sanctum vibrated with her sudden spike of distress.

"He is mine," she hissed, the ground beneath her feet cracking. "He was supposed to be the one thing that had nothing to do with the Diamonds. You won't keep him, little Pearl. I won't let you."

Even in her jealousy, a part of her was stunned. How had she never known? How had she missed the resonance of another Diamond in the man she had shared her life with? The irony was bitter; she had given up her physical form to escape the Diamond life, only for the man she loved to be pulled right back into the center of it.

The warp ended with a soft thud. Greg found himself standing in a massive, vaulted chamber that made the Reef look like a closet. The walls were carved from solid amethyst and lepidolite, glowing with a soft, internal fire. Thousands of Gems—mostly shades of purple and violet—were lined up in perfect rows, their heads bowed in silence.

"Behold!" the Lavender Pearl shouted, her voice amplified by the architecture. "The return of the Purple Light! The King of the Ionized Sky!"

Greg looked down at himself. He was already changing. The Pearl’s magic, or perhaps the Gem on his arm reacting to the environment, was weaving new clothes around him. His tattered shirt and sweatpants were being replaced by a long, regal coat of deep plum, trimmed with silver fur and embroidered with stars that actually seemed to twinkle.

"Whoa, easy on the wardrobe!" Greg yelled, trying to peel off the shimmering fabric. "I’m a size large, but I’m not a 'Your Majesty' size!"

"You are perfection," the Pearl insisted, her eyes misty. "We must get you to the Spire. The other Diamonds have already been notified. They are on their way."

"The others?" Greg’s heart hammered against his ribs. "You mean White, Yellow, and Blue? They’re gonna see me like this?"

"They will recognize their brother," the Pearl said firmly.

Just then, the warp pad behind them flared to life. Steven, Garnet, Amethyst, and Pearl came tumbling out, weapons drawn.

"Let him go!" Steven shouted, his shield manifesting in a burst of pink light.

"Stop!" Greg held up his hands. "Steven, don't! I think... I think they actually think I’m their boss."

The Lavender Pearl turned to the Crystal Gems, her expression hardening. "You bring weapons into the presence of a Diamond? You are lucky his brilliance is merciful."

"He’s my Dad!" Steven countered, stepping forward and placing himself between Greg and the Pearl. "And he’s staying with us!"

"He belongs to the stars," the Pearl said, her voice dropping to a low, melodic hum. "Look at him, Steven Universe. Can you not see the change?"

Steven looked. Greg was taller. Not just because of the boots, but his posture had straightened. The lavender glow in his eyes was becoming more intense, and the air around him smelled like ozone and expensive cologne.

"Dad?" Steven asked quietly.

Greg looked at his hands. They were steady. For the first time in his life, the chronic ache in his joints was gone. He felt powerful. He felt... ancient.

"I feel weird, Schtu-ball," Greg said, but his voice had taken on a resonant quality that vibrated in the floorboards. "I feel like I remember this place. But I’ve never been here."

"That’s the Diamond essence," Garnet said, her voice full of caution. "It’s waking up because you’re home."

"But Earth is his home!" Amethyst yelled. "He’s got a van! He’s got a car wash!"

"He has a galaxy," the Lavender Pearl corrected.

As the two groups stood at an impasse, a shadow fell over the great hall. A massive ship, shaped like a pair of elegant, reaching hands, began to descend toward the docking bay outside. The White Diamond sigil glowed on its hull.

Greg gulped. "I don't think I’m ready for a family reunion."

Steven took his father’s hand, his grip firm. "We’re not leaving you, Dad. Diamond or not, you’re a Universe. And Universes stick together."

Deep within the gem on Steven’s chest, the phantom of Pink Diamond watched the monitors of Steven’s eyes. She saw the Lavender Pearl’s hand resting on Greg's shoulder. She saw the way the purple Gems looked at him with adoration.

"Enjoy it while you can," Pink whispered to the darkness. "But he doesn't belong to you. He never will."

The doors to the Great Hall began to groan open, admitting a blinding white light. The era of Greg Universe, the simple man from Earth, was ending. The era of the Purple Diamond had begun, and the galaxy would never be the same.
