Editing Ouroboros (section)

===Ouroboros being born===
Soon after [[SubSonic]] was verified by Combined,<ref>https://www.youtube.com/watch?v=F-AfSPnjIcM</ref> Viprin said he had about sixteen more mega-collaborations planned, two of which were set to be Extreme Demon levels. On 10 September 2017, Viprin released [[Digital Descent]], one of the Extreme Demon levels he was talking about (also verified by Combined).<ref>https://www.youtube.com/watch?v=W6PDdaXSafw</ref> On 17 March 2018, Viprin uploaded the first preview of Ouroboros.<ref>https://www.youtube.com/watch?v=pppCE0WVi00</ref> The parts featured Viprin's part and Loserchik67's part. 

About seven months later, on 1 October 2018, Viprin uploaded the second preview of Ouroboros.<ref>https://www.youtube.com/watch?v=0OCS_7H_A4E</ref> The parts he previewed in this video were the first five parts of the level, [[AbstractDark]], Terron, Rustam/TrusTa, [[Darwin]], and TheDevon. He stated in the description that TrusTa would verify the level once it was complete.

Around the end of 2018, Viprin stated that TrusTa would no longer be verifying Ouroboros due to 'real-life stuff' and would be giving it to knobbelboy. It would be revealed to the public on 6 January 2019, when Viprin uploaded the third preview of Ouroboros to his channel.<ref>https://www.youtube.com/watch?v=KeVOIxzoaFM</ref> This video features the first nine parts of the level. Eventually, in late February 2019, Ouroboros was finally finished, and knobbelboy got straight to work on verifying.
