It grants no power freely, offers no redemption, only a whisper:The world is a stage. Your role is the villain. Play it well.In a realm where betrayal is currency and power is the only law, William does not resist fate—he embraces it. Every alliance is a move on the board. Every rival, a piece to be sacrificed. Every betrayal, already foreseen.But even a villain is not invincible. Enemies rise. Shadows scheme.
