The White Diamonds and the Palace of Light
At the very centre of the Marble Kingdom stood the shining city of Lumina — a breathtaking place built entirely from crystal towers, silver bridges, and glowing white stone that sparkled day and night.
And ruling over the city’s most magnificent palace were the legendary marbles known as the White Diamonds.
The White Diamonds were famous throughout the kingdom for their dazzling beauty and wisdom. Their marble shells shimmered with brilliant white patterns that reflected rainbow light like polished diamonds beneath the sun.
Wherever they rolled, tiny beams of light danced across the ground.
Some marbles believed the White Diamonds were magical.
Others believed they were simply very good at polishing themselves.
Bernard the talking dog personally believed the second explanation.
One bright morning, Jack Mitchell arrived in Lumina after receiving an urgent royal invitation sealed with a glowing crystal emblem.
Inside the palace, towering crystal chandeliers filled the grand halls with shimmering light while marble musicians played soft silver instruments beside enormous diamond fountains.
Waiting near the throne room stood Queen Diamara — leader of the White Diamonds.
Her shell glowed so brightly that Bernard had to squint.
“She’s shinier than the sun,” he whispered.
Queen Diamara welcomed them warmly but her expression remained troubled.
“The Heart Prism has been stolen,” she said quietly.
The entire palace fell silent.
Jack frowned.
“What’s the Heart Prism?”
Queen Diamara pointed toward the centre of the palace ceiling where an enormous empty crystal frame hung above the throne hall.
“The Heart Prism powers Lumina.”
Long ago, the White Diamonds had created the magical crystal to spread light throughout the city. Without it, Lumina’s crystal towers would slowly darken forever.
And already the effects had begun.
Across the city, lights flickered weakly.
Crystal bridges dimmed.
And giant diamond towers slowly lost their glow.
Outside, nervous citizens gathered beneath fading lanterns.
“If the city goes dark,” warned Queen Diamara, “Lumina may collapse into the Crystal Gorge below.”
Bernard blinked.
“You built the city over a gorge?”
“It was architecturally ambitious,” replied one White Diamond proudly.
Suddenly alarms echoed throughout the palace.
The great crystal windows darkened.
And a voice boomed across the city.
“Lumina’s light belongs to ME now!”
Far above the palace rooftops floated a strange black airship covered in dark crystals and silver sails.
Standing aboard it was a mysterious marble wearing a silver mask.
The Shadow Jeweller.
Years ago, he had once been one of Lumina’s greatest crystal makers. But after becoming obsessed with creating “perfect eternal diamonds,” he vanished into the mountains beyond the kingdom.
Now he had returned.
And he had stolen the Heart Prism.
“The White Diamonds waste their precious light on celebrations and beauty,” he sneered. “I shall create a perfect crystal empire instead!”
The Shadow Jeweller activated the stolen prism.
Dark energy spread across the sky while giant crystal storms formed above Lumina.
The city lights dimmed even further.
Jack looked serious.
“We have to get that prism back.”
Using royal crystal gliders, Jack, Bernard, Queen Diamara, and several White Diamonds soared high above Lumina toward the Shadow Jeweller’s floating airship.
Bernard absolutely hated this.
“Why are we flying again?!”
The airship hovered above the Crystal Gorge surrounded by swirling crystal debris and lightning-like beams of reflected light.
As they landed aboard the ship, they discovered giant crystal machines everywhere — spinning cutters, glowing furnaces, and enormous unfinished diamond towers.
At the centre of the ship floated the stolen Heart Prism.
But something was wrong.
The crystal had become unstable.
Dark cracks spread across its surface while dangerous beams of light shot wildly through the ship.
“You’re destroying it!” shouted Queen Diamara.
The Shadow Jeweller laughed bitterly.
“Perfection requires sacrifice!”
The unstable prism suddenly exploded with energy.
CRAAAAASH!
Crystal walls shattered.
The airship lurched sideways.
And giant crystal towers aboard the ship began collapsing into the gorge below.
“If the prism shatters completely,” cried Queen Diamara, “the entire city will lose its light forever!”
The only way to stabilise the Heart Prism was to surround it with pure reflective light from the White Diamonds themselves.
Without hesitation, the White Diamonds rolled together around the crystal chamber. Their shining shells reflected brilliant beams of light into the cracked prism.
Silver.
White.
Rainbow crystal light filled the entire ship.
The Shadow Jeweller shielded his eyes in shock.
“That’s impossible!”
Jack quickly pulled the unstable machine controls apart while Bernard accidentally smashed a crystal engine with a falling toolbox.
“I meant to do that!” Bernard shouted.
Then suddenly…
BOOOOOOM!
The Heart Prism released a magnificent wave of pure white light across the sky.
The crystal storms vanished instantly.
The cracks disappeared.
And far below them, the city of Lumina burst back into brilliant glowing life once again.
The Shadow Jeweller fell silently to his knees.
Queen Diamara rolled toward him calmly.
“Light was never meant to be owned,” she said softly.
“It was meant to be shared.”
That evening, the White Diamonds held a spectacular celebration across Lumina. Crystal fireworks exploded across the sky while the glowing towers reflected colours across the entire Marble Kingdom.
Jack smiled as music echoed through the shining palace.
“It really is the brightest city in the world.”
Bernard glanced at his reflection in a nearby diamond wall.
“Yes… and I appear to have been polished by accident.”
