Vanitas

Story and background

Created when Xehanort forcibly extracts darkness from Ventus. His connection to the Unversed and the χ-blade makes him the destructive mirror of Ventus's struggle.

Events and connections in the series

Xehanort wanted a collision between pure light and pure darkness powerful enough to forge the key-blade. When Ventus resisted using his darkness as instructed, Xehanort ripped that darkness out of his heart. The result was Vanitas, an aggressive, separate being tied to Ventus. The extraction shattered Ventus's heart and nearly killed him. It also exposed the ancient Darkness that had followed Ventus across centuries. Vanitas is not simply a second ordinary human boy; his identity is entangled with the original Darkness.

During Terra and Aqua's Mark of Mastery examination, Aqua passed and Terra failed. Eraqus feared Terra's darkness; Xehanort recognized how that shame could be exploited. Soon Xehanort disappeared, while creatures called the Unversed began invading other worlds. Terra was sent to investigate, Aqua was told to watch him, and Ventus departed when Vanitas suggested Terra was in danger. Their paths separated, though each believed they were doing the right thing.

Terra desperately wanted to be seen as worthy of mastery. He encountered villains and made disastrous choices, yet his deepest desire remained to protect his friends. Xehanort fed his insecurity, appearing to offer understanding where Eraqus offered suspicion. Aqua tried to fulfill her responsibilities without abandoning Terra or Ventus, but her surveillance made Terra feel betrayed. Ventus pursued them both while Vanitas tested his strength, deliberately driving him toward the final clash that Xehanort wanted.

Historical context

Terra, Aqua and Ventus grow up together under Eraqus, but Xehanort exploits their separate hopes and fears. The three campaigns of Birth by Sleep tell overlapping sides of the same tragedy, whose aftermath continues through Castle Oblivion and the Realm of Darkness.
