Write the first chapter of a detailed story with a lot of dialogues for a specific context, based on this: (Yu Yu Hakusho Hiei is alone, looking at his reflection in a river, not too far from a village of ancient nordic origins. Soon a calm and strong woman, native of the planetoid on the contrary of all the characters approach the demon, asking him what's wrong. Hiei is not so kin to be nice, with her, but she eventually win over him with her own arguments, starting to reassure him)

The context is this: [Once upon a time, in a distant corner of the cosmos, there was a planetoid the size of Jupiter. This colossal celestial body was home to several ancient civilizations, each one unique in its own right and estemmed way of life. What made this planetoide even more peculiar was the fact that thousands of characters from various universes, each with their own abilities and strengths, found themselves inexplicably transported there.
Upon their arrival, the characters discovered that their individual powers varied greatly. While some were as mighty as they had been in their own realms, others found that their strengths had been diminished. To even the scales, many warriors who had once been weaker than others were now endowed with a newfound power that brought them on par with the mightiest heroes and villains.
As time went by, the myriad characters began exploring the vast and diverse landscape of this enigmatic planetoide. While some sought to learn its origin, many others realized that they could increase their own power through effort and dedication, effectively “leveling up” and ultimately surpassing their fellow fighters.
For several months, they traversed the sprawling expanse of the planetoid, challenging and defeating other warriors, as well as forging alliances with those who shared their ideals.
One fateful afternoon, as one of them delved deep into the forests of the planetoid, he stumbled upon a mysterious chamber hidden beneath the roots of an ancient tree. The entrance, though well-hidden, bore the signs of past explorations. Piqued by curiosity, this guy ventured inside.
The chamber was dimly lit by the flickering light of magical torches, revealing dusty shelves filled with scrolls and documents that had been left untouched for eons. As he carefully scanned the room, he found one peculiar document that had seemingly fallen on the ground. He unfolded it gently and began to read.
“What’s this? ‘Cloning Experiment Log’?” he wondered aloud, his curiosity burning even brighter. As he continued to peruse the document, a terrible truth began to dawn on him. All of the characters transported to this planetoid, were not the originals, but mere clones of these warriors. The original ones were still living their lives in their respective universes, unaware of the existence of their duplicates on this colossal celestial body. And what was more shocking was that there literally was no way out for them: the planetoid, would be their home now...
The grim revelation would send shockwaves through every character that would eventually find out about this revelation. Some characters will be devastated, while others will question their own existence and purpose, and some more... It's unclear what they'll feel.]
