Our bodies are then teleported from their location to where Creed, Natsu, and Gray are in three great flashes of light. Our appearance briefly lights up the darkness, our eyes slowly opening. Ventus's armor is automatically summoned as he enters the darkness, Vanitas is unaffected by the darkness, for he is a physical form of Ventus's darkness, and I have my hood on.
As you light up the darkness, a figure can be seen, the size of a human, dressed in a ragged cloak Then, the light is gone, and a figure can be felt, greater than any you have felt before. Vanitas feels somehow that he's done. That he's home. That nothing needs to be done, and that this is simply the end. A sense of finality descends upon him, as happiness, anger, pain, sadness and hope all drain from him, replaced by an empty finality, a certainty of death. Roxas feels his good deeds smothered, as life seems to end here. He's small. Nothing. An inconsequential blip on the cosmic radar, as for him, too, he is drained. Ventus becomes empty, his breathe resisting him drawing it, as his body becomes slack. All three, first brave heroes, feel like they should simply lie down. Give up. Roll over and die. The world is empty and meaningless, and their life has no meaning, no importance. There is no reason for them to exist, and they shouldn't. Hit even harder than the Fairy Tail mages, soon they're on their knees, unable to move, simply awaiting their death.
((More emotion, regardless of the emotion, makes this easier to resist. The heartless dude is screwed))
