Prologue: The past of the Sapphire Star

The forge was alive with the sounds of metal meeting fire, the rhythmic clang of hammers and the hiss of molten steel everytime it dipped in the water reverberated throughout the workshop. The younger brother stood beside a worn workbench, his wide eyes wandering over the array of weapons laid out before him. Lances, swords, shields, bows, Hunting Horn, all stood on their respective storage, their edges keen, their hilts polished smooth from use. His fingers hovered above a massive charge blade, its form both imposing and elegant, as if it carried stories of a hundred battles within its steel.

"That one," the older brother's voice came from behind, rough but carrying a warmth that always pulled the younger one in, "was my favorite. The charge blade. Versatile, Brutal but efficient."

The younger brother turned, his gaze filled with a mix of awe and curiosity. "Did you really use all of these? In those... stories you told me?" his eyes darted towards the weapons aligned in the smithy.

A small smile tugged at the corner of the elder brother's mouth. His hands, rough from years of battle and forging, traced the edge of the lance beside the charge blade. "I did," he said softly, his eyes distant as memories of another life stirred to the surface. "I fought monsters you couldn't even imagine, beasts that could level mountains, that could scorch the land with a breath." He paused, as if searching for words to describe what couldn't truly be explained. "Elder Dragons... beings of immense power, each one like a force of nature."

The younger brother's heart raced. He had always loved these tales, but there was something different this time—something deeper, as if the stories were more than just fables spun for entertainment. "What were they like?" he asked, his voice hushed with awe.

The elder brother let out a long breath, his eyes returning to the forge, but his mind clearly far away. "Each one was unique. There was Teostra, the Emperor of Flame... his presence alone would cause the air to shimmer with heat, the ground cracking beneath his fury. And Kushala Daora, the wind incarnate. You'd never see her coming, only feel the storm she summoned around her." He shook his head, lost in the memory of those battles. "But none were as terrifying as Fatalis, the Black Dragon. It was said that its very breath could melt kingdoms, that it razed entire civilizations to the ground in ancient times."

The younger brother's breath caught in his throat. He could almost picture it—the sheer scale of these creatures, the terror of facing something so vast, so primal. "Are they... real?" he asked, his voice barely above a whisper, as if the answer could change everything.

The elder brother shook his head slowly, though the sadness in his eyes told a different story. "No... not in this world." He placed a heavy hand on his younger brother's shoulder. "Fortunately, this world doesn't have them. Orario has its own dangers, but Elder Dragons... they're something else."

The younger brother's brow furrowed. "What about the one-eyed black dragon here? The one from Orario? Is it anything like Fatalis?"

A bitter laugh escaped the elder brother's lips as he leaned against the forge, continuing the forging process. "The Black Dragon of Orario is a terror, no doubt. But Fatalis... is on a different level. It was more than just a beast. It was destruction given form. There's a reason everybody feared it above all else."

The younger brother's eyes sparkled with fascination, and a question hung on his lips. "If... If Fatalis isn't real here, then those stories you told me... they're from somewhere else, aren't they?" His gaze searched his brother's face, piecing together the truth hidden in plain sight for so long.

For a brief moment, the elder brother's expression faltered. He wasn't just retelling stories from a game. He had lived them. Reincarnated into the world of Danmachi, he had kept his past a secret, offering only fragments of his experiences to his younger brother, disguising them as mere tales. Those battles, those dragons, the elder dragons... they had been real, once. And the weight of that knowledge was something he carried alone. He wouldn't burden his brother with that truth, not yet.

"Stories from another world," he finally said, his voice soft. "Tales to help you, if you ever become an adventurer here."

The younger brother's eyes shone with excitement, his thoughts already racing ahead. "I want to fight one," he declared suddenly, his voice filled with determination. "A dragon. I want to be as strong as you were... are."

The elder brother stared at him, surprised but not entirely shocked. He had seen that fire before and even felt it within himself when he had first taken up arms in the world of monsters and dragons. But here, in this world? that fire had a different meaning.

A far more dangerous one.

"You don't know what you're asking for," the elder brother said quietly, though there was a note of pride hidden beneath his voice. "Fighting an elder dragon isn't just about strength or skill. It's about survival. You're facing something far older, far more powerful than you can imagine."

"But I want to try," the younger brother insisted, his eyes full of that same unwavering resolve that the elder recognized all too well.

The forge crackled around them, the tools of their shared history lying in wait, a reminder of battles fought and stories retold. The elder brother gazed down at the weapons, each one a relic of a world he no longer belonged to, and nodded slowly.

"One day," he said, though his voice was heavy with a past his younger brother couldn't yet understand. "But for now, let's make sure you're ready for the battles in this world first." A smile bloomed in his face reaching out his arms to pat his brother's head.

Let's hope it does not come into that. The big brother thought to himself. Not that i have a choice. He sighed before dragging a weapon alongside him, a huge weapon that towers every single weapons in the smithy in both versatility and power.

May the sapphire star guide your way, my dear brother.
