This story has been dead for several months now, however I think all of you deserve some kind of closure. So here it is.
This was caused by a number of different things... My twitter account getting suspended before I could archive a chunk of it was a huge reason. Another one was the retcon getting rid of one arc that I thought of as too crucial to continue without it at the time.
Here's how the story was gonna go before the retcon: Karkat started digging a giant hole in the ground. Why? No idea. He finally learned how to fly when trying to get out of said hole. He then attempts to kill Zebruh (if you read the pre-retcon version of the story, then you know about all the setup for this). If he fails and dies instead, he would be brought back as a robot. If he succeeds and survives, then I would later find another way for him to die and also be brought back as a robot. The ultimate illusion of choice.
That's basically all I had. See you again someday in another story.
