I Tampered with the Human Epic

Every lie I tell becomes reality. At first, I just wanted to survive by lying to my pursuers that "the princess is dead". As a result, all the portraits of her in the world rotted into ashes at that moment. Later I joked, "Under the continent sleeps a world-destroying ancient dragon." That night, earthquakes occurred in the seven kingdoms at the same time, and shuddering heartbeats could be heard from the ground. Now, the coalition forces are approaching the city and they want me, the "prophet", to be responsible for the end of the world. I laughed and told the biggest lie to the world: "The disaster never happened, it was just a nightmare for you." When everyone woke up in a daze, I was the only one who remembered all the erased realities. And I discovered that some "truths" are scarier than any lies.
