Here is a Omake
@Kingster, I write about the Empire footsoldier facing the Black Arms scouting force for the first time:
Shadows of Dominion
Sergeant August Klein never thought he'd see the day the Empire would be truly on its own. Gallia had been conquered, its quiet streets under Imperial rule, but after the event they'd come to call "the Shattering," everything had changed. The night sky had fractured, twisting into strange, new colors. One moment, they were securing a supply line to Randgriz; the next, the very air felt wrong. Strange towers rose in the distance, structures that hadn't been there before. Communication lines with the homeland had gone dead, and new threats loomed in the shadows of this alien world.
As the Imperial occupation adjusted, their goals shifted from conquest to survival. August's superiors established fortified outposts, turning Gallia's towns into bases, and every soldier was reminded that the Empire was Gallia's ruler now—cut off from their homeland or not. They would adapt and rule Gallia just as their Emperor intended.
But the soldiers had begun to notice things. Shadows moved in ways they hadn't before, and unearthly sounds echoed in the distance. The higher-ups dismissed it as nerves until scouts reported seeing strange, black creatures that seemed to melt into the darkness, their crimson eyes glowing like embers. And then the attacks began.
August had been stationed just outside Bruhl with his squad when the first clash happened. It was night, and they were on patrol near a hill overlooking the valley. August looked out over the land, thinking how peaceful it all seemed. But then he noticed the faintest flicker of movement. At first, he thought it was just the wind shifting shadows in the trees. But then he saw them: figures moving through the darkness, their bodies inky black and their movements fluid and predatory.
A cold dread washed over him as he realized these weren't ordinary creatures. He grabbed his rifle, signaling to his squad. "Eyes up! We've got company—something's coming!"
The creatures, who they later learned were called the Black Arms, moved swiftly. They didn't announce themselves, didn't show any fear. They simply attacked, claws gleaming as they tore into the Imperial line. Bullets seemed to pass through them like shadows, their bodies bending and shifting around the shots. August's squadmate, Stein, took a slash across his chest, dropping to the ground with a scream.
"Focus fire!" August shouted, firing wildly at the nearest creature. He managed to score a hit, and it staggered back, but only slightly. It turned its eyes to him, glowing with a terrifying intelligence. The sheer malice in that gaze shook him to his core.
Realizing their weapons were barely effective, August fumbled for a grenade, tossing it as far as he could toward a group of the creatures. The explosion tore through the night, sending some of them scattering. But as the dust settled, the creatures emerged almost unscathed, their forms flickering back into the darkened landscape.
One of his men, Kaspar, shouted, "They're barely taking damage! What are these things?"
"They're soldiers like us," August replied, his voice steady but his eyes wide. "They bleed; we just need to find how."
The Imperial forces began falling back, regrouping to form a defensive line. The Black Arms pressed their advantage, slipping through cracks in their formation, tearing into the soldiers with unearthly precision. August was forced into close combat, ducking as one creature slashed at him. He felt its claws skim his helmet, tearing it from his head. It was only by instinct that he managed to raise his rifle and drive the stock hard into the creature's head. It staggered, momentarily dazed, and August fired a shot directly into its crimson eye.
The creature dissolved into mist, vanishing into the air.
"Headshots!" he yelled to his squad. "Aim for the head!"
Gradually, the Imperial soldiers adapted, targeting the creatures' heads and learning to move in groups to cover each other's backs. The battle was grueling, but with each victory came a bitter sense of survival rather than triumph. The Black Arms didn't retreat—they simply stopped attacking when enough of them had fallen, slipping back into the darkness as if they'd never been there at all.
When morning came, the battlefield was quiet, littered with bodies—both Imperial and the strange, dissolving remains of the Black Arms. August and his men stood in silence, gazing at the aftermath. Their victory was a hollow one. Gallia may have been their new home, but they realized it was now a place filled with unknown dangers. They'd been invaders before, but now they were survivors, and this world wasn't one they'd conquer easily.
As they collected their dead and reinforced their defenses, August spoke to his men, hoping to rally what remained of their morale. "The Empire may be gone, and we may be alone, but we're still soldiers. We'll adapt, and we'll fight. We might not have our homeland, but we have each other. And whatever these creatures are, we'll find a way to beat them."
But in his heart, he knew that this war was different. They were no longer fighting for the Empire or its conquest of Europa; they were fighting for survival in a land that had turned hostile in ways they couldn't yet understand. And as he gazed over the twisted landscape beyond Gallia, he knew one thing: they were in for a long, brutal struggle.
Obs: Black Arms are terrifying in my opnion both GUN, a global fight force, and Eggman struggle to hold the line long enough before a solution come and they pretty much would have lost if Gerald Robotnik plan. These Imperials lucky this was just a scouting force they face.
I imagine the forntlines between the Empire and Black Arms have devolved intro trench warfare since they can't advance the land claimed by the Black Arms so they only defend for now.
