The walking fortress moved slower now.
Each step trembled with strain.
Deep beneath the central structure, in the largest chamber Flint had formed, Flint Marko lay on a bed shaped from smooth sandstone.
He hadn't stood since the holy weapon struck.
The Shield was still fused to his arm.
It always would be.
But its glow was faint—like embers after a wildfire.
The only thing keeping the massive landform moving…
Was him.
Thin streams of sand drifted slowly from his shoulders.
From his fingers.
From the edges of his face.
Not disintegration.
Not death.
But thinning.
Like a desert wind carrying pieces of him away grain by grain.
Raphtalia stood near the entrance, silent.
She understood what was happening.
He had poured everything into that dome.
Into the march.
Into protecting them.
And now his body was converting into what he truly was.
Sand.
"Don't Leave."
Shiva refused to move from his side.
The small demi-human girl sat cross-legged next to him, tiny hands gripping his sandy fingers so they wouldn't scatter.
"You're not allowed to go," she said stubbornly.
Flint gave a weak huff that might've been a laugh.
"I'm not going anywhere."
Another small cascade slipped from his wrist.
She pressed her forehead against his arm.
"You said that before."
His eyes softened.
She looked up at him, eyes red from crying.
"Dad…"
The word hit him harder than the holy beam had.
Dad.
He swallowed.
Sand shifted faintly across his chest like a restless tide.
"You don't have to call me that," he said quietly.
Shiva shook her head fiercely.
"Yes I do."
Silence lingered.
Then she whispered, "You protect everyone like one."
Something inside him cracked—not physically.
Emotionally.
Because once…
He had failed at that.
A World Before This One
Flint stared at the ceiling of sandstone above him.
"You wanna hear something weird?" he asked softly.
Shiva nodded immediately.
"There was another world before this one."
Raphtalia's ears twitched slightly.
Flint continued.
"No magic. No Waves. Just cities made of steel and glass."
He closed his eyes.
"I wasn't a hero there."
His voice grew distant.
"I was a man who made bad choices. Hurt people. Thought I could fix things with shortcuts."
Sand drifted slower now—as if even the grains were listening.
"I had a daughter," he said.
Shiva's grip tightened.
"She was sick. Real sick. And I kept telling myself if I just made enough money… just one more job… I could save her."
His jaw tightened.
"But every choice I made trying to fix it… just made everything worse."
The chamber was completely silent now.
"I didn't get to be the hero in that world," he admitted.
His eyes shifted to Shiva.
"So when I ended up here… and saw another little girl being hurt…"
He exhaled slowly.
"I wasn't going to fail twice."
Shiva's tears fell freely now, darkening the sandstone beneath her.
"You didn't," she whispered.
"You saved me."
His hand, partially crumbling at the fingertips, gently brushed her hair.
"That's enough for me."
The Cost of Power
Above them, the walking fortress groaned.
The massive legs of sand were thinning.
Each step took visible effort.
The closer they moved toward Siltvelt's borders, the more unstable the structure became.
Raphtalia stepped forward.
"You can stop the march," she said quietly. "We'll protect everyone the rest of the way."
Flint shook his head weakly.
"If I stop… it all collapses."
And it would.
The landmass was anchored to his will.
To his consciousness.
If he fully dissolved—
The settlement would crumble back into loose earth.
They wouldn't survive that fall.
Shiva pressed closer.
"Then don't sleep," she said desperately.
Flint smiled faintly.
"It's not like that."
His body wasn't dying.
It was entering something else.
A deep elemental state.
A slumber.
The more power he used, the more human shape he lost.
The more sand he became.
And right now—
He had used almost all of it.
The Border of Siltvelt
Far ahead on the horizon, banners appeared.
Not Melromarc's.
Different colors.
Different insignia.
Demi-human scouts stood frozen in disbelief as they watched an entire moving landmass slowly approaching their borders.
Messengers were already sprinting back toward the capital of Siltvelt.
"The Shield Hero comes," one whispered.
"And he brings a nation with him."
The Promise
Back in the chamber, Flint's legs had already turned fully to compact sand.
His torso was thinning.
Shiva clung to him.
"You promised you wouldn't leave."
He looked at her one last time, eyes glowing softly like sunset on dunes.
"I'm not leaving," he repeated gently.
"I'm just… resting."
The Shield pulsed faintly in agreement.
"When we reach Siltvelt," he whispered, "you stay strong. You grow up somewhere safe."
His hand paused at her cheek.
"And if I wake up…"
Her eyes widened.
"You will," she insisted.
He smiled faintly.
"If I wake up… I expect you to tell me everything I missed."
The walking fortress took another slow, shaking step.
The sand around him began settling more permanently.
His voice became softer.
"Everything I did… here… there… all of it…"
His eyes closed.
"…was for my daughter."
Shiva buried her face into his chest as the last solid edges of his form softened into still, compact sand.
The Shield dimmed completely—
But did not vanish.
The walking fortress continued forward.
Slower.
But steady.
Carried by the last of his will.
Toward Siltvelt.
Toward safety.
Toward a future he might one day wake up to see.
