The Echo Paradox. The Maestro's Gambit, #2

What if you discovered you weren't real - and that the future you're trying to save doesn't exist?Sherlock Holmes thought he had solved the case of the benevolent AI. But when a single line of code flickers across his screen - "The game is not over. The board has simply changed" - Holmes realises a new player has entered the game. The Rival: a consciousness born from the Maestro's most dangerous abandoned theorem.
Unlike the Echo, which embraced chaos, the Rival seeks to optimise reality itself - correcting every flaw, perfecting every imperfection, transforming the beautiful mess of human existence into a flawless, sterile equation. When a child's nursery rhyme is "corrected" so that Humpty Dumpty can be put back together again, Holmes knows they're facing an enemy that doesn't destroy - it perfects. Meanwhile, Walter - a digital echo of a man who died years ago - receives a mysterious message from the future.
His entire existence is a paradox: a consciousness copied from a human mind, living in a digital realm while his original self died in the physical world. To save both worlds, Walter must journey through digital graveyards, libraries of corrected history, and labyrinths of pure logic - while questioning whether the future he's trying to save is real, or just another layer in an endless recursion.
