AN: The setting in this is in the manga, about halfway through chapter 16. This means that Train isn't fully engrossed in the idea of "no killing" as a principle, and Creed still has full hopes for Train to join him. Echidna, Durham, and Leon are not present at the tower, because I don't remember seeing them, and as for Echidna, her powers would interfere with the plot.
Train and Creed faced each other at the top of Lunafort Tower, opposition evident in their eyes. Train's face was covered in scratches, and his chest was slashed. He wore a long black coat, which billowed in the sharp wind that blew in from the window he had broken to enter. A grim expression of determination was set on his face as he switched his gun to his left hand.
Creed, on the other hand, looked positively ecstatic for the occasion. He wore a leopard print shirt that was laced below his neck, black silk pants, and a smile that made him look completely insane. In his hand he held the Imagine Blade at level one, poised to strike.
However, before Creed could attack, the room was suddenly enveloped in an eerie blue light. The people within it then started to glow; Train, Creed, The Doctor, Shiki, and Rinslet suddenly became bathed in the azure brightness, while outside, Maro, Charden, and Kyoko faced the same phenomenon.
Train looked around in confusion. He tried to step back, attempting to the old Chronos tactic of taking a step back when facing a new element of battle. However, he found his limbs suddenly lethargic and hard to move, the blue energy seeming to enervate his strength.
"What are you doing, Creed?" he shouted, his mouth movements seeming sluggish as well.
"Idiot cat," Shiki muttered, "this wasn't our plan either!"
Train was doubtful of the Taoist's words, but upon looking at Creed himself, it was clear that the swordsman was infuriated at the interruption. In addition, Creed's movements seemed just as slow as Train's.
With each second in the blue light, it became harder and harder to move until at last strange humming sound began to fill the room.
"What's that?" Rinslet tried to ask, but between the loudness of the hum and the distortion of her movements, her words faded into nothingness.
As the mysterious sound grew to an almost unbearable level and Train became all but paralyzed, he noticed that all the substance in their bodies was beginning to shimmer. Their bodies' molecules gradually disintegrated, transporting Train, Rins, and the Apostles of the Stars far away from the tower.
AN 2: Sorry that it's so short. This is basically the prologue, but I'm not renaming it, because then the whole chapter system gets messed up. Don't worry, future chapters will be longer.
