Speculative Sciencs

Lancelot Haier came from a dynasty of politicians who had ruled with tyranny and oppression. Despite those origins, he despised his family and was willing to help the citizens who had long suffered under their rule. However—before he even had the chance to change his country, the people revolted. His entire family was executed, and he was killed along with them. In his final moments, he wished for a second life—one where he could redeem himself and carry the sins of his bloodline. Unexpectedly, that wish was granted. He was reincarnated into another world as the crown prince of the Kingdom of Aragon. But in this world, everything felt backward. The country was ruled by an absolute monarch. Feudalism was the norm. Technology resembled that of the late 1700s. Fortunately, in his past life, he had earned degrees in both mechanical engineering and political science—knowledge he once hoped to use to reform his homeland. Now, it seemed he would use them here instead. He would use his modern knowledge to transform the lives of his people, industrialize his territory, gain the upper hand in technology, and form alliances with foreign nations—all while navigating the treacherous waters of internal affairs and politics. P.S While Reincarnated as the Crown Prince draws inspiration from historical settings, political systems, and technologies of the late 17th and early 18th centuries, this work is entirely fictional. All characters, governments, names, and events—although some may resemble real-world history—are products of the author’s imagination or are used in a fictionalized, altered form for narrative purposes. This novel is not a historical account. It should not be interpreted as a factual representation of any real monarch, nation, revolution, or political figure. Lancelot Haier, his backstory, and the alternate version of different kingdoms portrayed here are entirely original creations. The inclusion of familiar concepts like feudalism, industrialization, and political reform serves the plot and world-building, not historical documentation. Readers seeking accuracy in history are encouraged to consult verified academic sources. This story is a creative work meant for entertainment, character development, and speculative exploration of “what-if” scenarios rooted in alternate history. Thank you for reading, and I hope you will enjoy the journey.

Gaia City stands as the pinnacle of human advancement—a sprawling, walled metropolis where science has given birth to the extraordinary. Within its boundaries live Gaias, individuals born with Arthem circuits, synthetic pathways infused with Psi Waves and the mysterious energy known as Metra. Ranked from Eta to Alpha, Gaias are classified, studied, and controlled under a rigid system designed to maintain order and suppress the unknown. But science can only explain so much. Beyond the city's borders dwell the Mergus, wielders of pure Metra through forbidden Ancient Scripts and sacred texts long dismissed as myth by Gaia City's researchers. Unlike Gaias, Mergus tap into forces unquantifiable, echoing lost wisdom and primal power. Contact between the two worlds is outlawed—for good reason. Exposure to raw Metra could cripple or kill a Gaia, disrupting their Arthem at the core. Ryouma Winslow, an Eta-class Gaia dismissed as a nobody, had no intention of getting involved with either side. But everything changes when he crosses paths with Archive (Shiro), a strange girl with fractured memories and a presence that doesn’t belong in Gaia City. Helping her seemed simple—until restoring her mind reveals a truth that shatters the world he thought he knew. Now entangled with rogue Mergus factions, hunted by unseen forces, and navigating fragile alliances with powerful Level Alpha Gaias like the electrifying Mei Tokisaki, Ryouma finds himself drawn into a multilayered conflict that transcends science, challenges belief, and threatens the foundations of Gaia City itself. Because in a world split between science and sorcery, the greatest danger is a boy who doesn’t fit into either side. Author's Note to Readers: This story draws clear inspiration from the Toaru series (A Certain Magical Index / Scientific Railgun), and longtime fans will notice structural and tonal similarities in its arcs, setting, and faction dynamics. While some adaptations and elements may feel familiar, please know that the world, characters, power systems, and underlying themes in A Certain Undefined Gaia are entirely original and unique to this work. Think of it in the same way that fans appreciate both Mushoku Tensei and TBATE—similarities exist, but each story carries its own voice, meaning, and direction.

"There is an old saying that a person is but a mosaic of memories. But it is not the memories themselves that shape us, rather the choices one chisels from their shattered pieces — even those born in silence, even those carved in pain." "When the World Forgot Itself" is the Main Story and the largest part of the large Universe of Luminastra. It explores the delicate, often fractured nature of identity through a tapestry of fantasy and speculative genres. At its core lies an investigation into how memory — both personal and collective— shapes reality, yet never fully defines it. Instead, it is the conscious act of choosing what to hold onto, what to discard, and what to transform that forms the essence of self. Drawing from dark fantasy’s shadowed realms and epic fantasy’s vast horizons, the story delves into psychological and philosophical questions of existence, trauma, and resilience. It confronts the haunting echoes of forgotten histories and suppressed truths, inviting readers to consider how the past continues to live within us, sometimes as silent burdens, sometimes as sources of hope.

Diamond and Aika had been found by Sofia and Mark in a dark alley, and they took them in as their children. Although they had developed a strong bond as a stepfamily, the details of their past remained a mystery. It was speculated that their biological families had abandoned them, but in truth, there was a more complicated reason for their evacuation from a dangerous situation. Since their adoption, Sofia and Mark had been curious about the children's unique appearances. Diamond had bright yellow hair and mismatched eyes—yellow on the right and light blue on the left.

However, the shadow of that past loomed over him, and he stood there, filled with fear, tears, and disbelief as the tragedy he had witnessed unfolded before his very eyes.
