While this number only appears in the Vanitas Remant battle of Birth by Sleep Final Mix, "Enter the Void" has quickly surged in popularity among the fandom. HypochondriacPiano returns to bring the piece to life, and her performance is anything but "Unversed" with our ears.
While "Enter the Void" is technically one of Vanitas's themes, its energy and direction follow the unraveling of the Wayfinder Trio (Terra, Aqua, and Ventus). Throughout Birth by Sleep, these three find themselves manipulated as pieces in an ancient game of light against darkness. In many ways, Vanitas fares no better, being created and valued specifically because of his potential to forge the X-Blade. While Master Xehanort may have been playing Terra when he described Vanitas as an "abomination beyond hope of salvation," its pretty clear that the old man thinks of Vanitas as no more than a tool.
The paths of the these young people converge at a crossroads in the Keyblade Graveyard. "Enter the Void," a song encapsulating the process of losing oneself completely, is particularly apt for this moment. Ventus' words still give me goosebumps every time I hear them.
"I'm asking you, as a friend. Just . . . put an end to me."
