It's just them. Floating in space. For the rest of eternity.
The world in which they resided had been destroyed. As a result, the rest of that system, and later that universe, was thrown off balance and collapsed.
It all happened so fast. The world that had existed for so long. Just gone. All because of a wish. A wish for the world's destruction. A wish for the world to pay the price for what happened so many centuries ago. Their deal was made cleverly. Simply get the seven items in the slab where they were birthed, free him, and the wish would happen.
He did just that, and the wish was made. Though, he didn't live long enough to see that happen.
Now, as the universe around them slowly began to die out, the being of darkness held close his token. His last piece of that world, the host of the wishmaker.
He could find another universe for them, in due time. But for now, as it's finally silent, no interruptions, nothing to bother them, the darkness could hold, caress, and cherish the one bit of light he never could destroy. The one bit of light whose lumination, no matter how bright, he never minded.
The light's body was lax in his arms. Forever frozen in time until the darkness decided otherwise. Forever asleep while the universe around them is destroyed.
Forever intertwined with the being of darkness.
