I feature a protagonist who undergoes a significant transformation after encountering a mysterious object. My setting blends historical elements with fantastical concepts, and the narrative explores themes of destiny, free will, and the burden of knowledge. Though my protagonist's intentions were good, their actions lead to unforeseen consequences that threaten to unravel the very fabric of reality.

1. One key character is driven by vengeance and seeks to exploit the protagonist's newfound abilities.
2. The object in question bestows immense power but also carries a heavy price.
3. The narrative is set across various timelines and dimensions.
4. My protagonist is considered a myth among some societies.
