Summary: The sky had been filled with Earths, and they had gone up there to save them all. That was years ago.
Notes: I'm way happier with the premise than with this particular fic. I think this would work much better as a long, epic, angstslashy thing.
Knightum was perhaps the greatest hero in the multiverse, and they were perhaps his greatests foes. Now, after five years of constant struggle, it had come to this. Just the three of them, standing in the Waystation To The Infinite. A final battle for the ultimate power the dangerous duo had sought for years.
"Why?," asked Knightum. "Of all my foes, you two have been the most courageous, the most cunning, the most resourceful. I was taught to know my enemy as I know myself, and I know that your souls are good. Why this search for cosmic power? What would justify endangering the entire multiverse in this mad quest?"
The older of his enemies took off his domino mask in a final gesture. "Because it wasn't meant to be like this. The multiverse is wrong."
His companion narrowed his eyes. "We have to fix it all. Nothing personal." His eyes were glowing red.
