Dating back to June 17th, 2013, HeyMrDJ made a page called "Project X". It talked about the user MasterSkymning and DJ's investigation into Skyminings mysteriousness. Though nobody took DJ seriously when this page was uploaded, even deleted the same day- it is now recognized as one of the earliest warning signs in the war.
X is the clone we know today, but this clone was made 3 years after this page was made. This page made by DJ may not even be the earliest production into the clones. How far back the clone projects date may range from 2013 to possibly even earlier than that.
The contents of the page reads:
"OMG! REAL EVIDENCE: IS SKYMNING IMMORTAL? IS HE THE SUPREME BEING? OR IS HE JUST ANOTHER FAKE??!!!! FIND OUT HERE!!!!!!!!!
So..........I found out so far that SKYMNING could be A ROBOT AND NOT IMMORTAL. THIS IS SHOCKING NEWS. I mean now how did he die? and why could he heal so quickly?! BUT HE MIGHT NOT BE. HE MIGHT BE A DEITY. OR A HUMAN. WHAT IS HE?! I will post more results later."
Though this page seems almost as a joke, it has a lot more than we know of. If MasterSkymning is indeed what X became, it would explain the conversations where X breaks down. MasterSkymning still fought for the Venkons in despite of his irrationality.
Unfortunately there is no further research that can be done to this aside from reaching out to MasterSkymning himself. HeyMrDJ is dead. Our best bets are to say they aren't coming back anytime soon.
