    Summary

    The multiverse was never a place of quiet.
    There is a contant strive for balance.

    Creation and destruction.
    Positive and negative emotions.
    Pacifism and genocide.
    Even creators struggle along their own creations.
    But even with these massive forces, everything has managed to stay more or less the same.
    The common eyes don't see the battles between giants happening in their backyard.
    And for our story to begin, one of these forces must come out of balance, since when one big giant is tackled, others tend to fall aswell.

    It's a shame how such huge forces can be so, so delicate...

    Summary

    Change is a force that has toppled empires and left gods drowning in the seas of time. Many fight against it, only to be bitterly defeated. Others accept it and flow along the ever shifting tides.

    Nightmare and his gang are aware of both the good and bad that change can bring. They are the byproducts of irreversible change, and have come to accept their new lots in life even while they fight.

    But sometimes change is unpredictable and your current life becomes forfeit.

    Corruption flows and reveals ivory bones, but he was never given an opportunity to change, was he?

    Summary

    Killer had suffered multiple times from the hands of Nightmare, physically and mentally. But he remained standing by the cruel monster's side, enduring how Nightmare often plays with his head and relishes on his anguish right after. But one day, Dream visited him in hopes of convincing Killer that it's never too late to change. As expected, his first reaction was hostile not until it was mentioned that Nightmare can be fixed if they work together with his uncorrupted state from an alternate universe.

    While Dream has good intentions with this plan, Killer on the other hand has other things in his mind. After all, a dull blade's cut is more painful and lethal than sharper ones.
