Cloud9 League of Legends#Cloud9 Tempest

Cloud9's League of Legends division traces its roots back to the disbandment of Quantic Gaming's League of Legends roster, which included Nientonsoh, Hai, Yazuki, WildTurtle, and LemonNation. Following their departure from Quantic Gaming, these five players came together to form their own team called Team NomNom.{{cite news |last1=Melo |first1=Gabriel |title=Cloud9 entra no Mundial de LoL querendo quebrar tabu de não chegar nas semis |trans-title=Cloud9 enters the LoL World Cup wanting to break the taboo of not reaching the semis |language=es |url=https://www.espn.com.br/esports/artigo/_/id/4802532/cloud9-entra-no-mundial-de-lol-querendo-quebrar-tabu-de-nao-chegar-nas-semis |access-date=March 18, 2021 |work=ESPN |date=September 26, 2018}} However, their initial foray into the competitive scene faced an early setback when they were eliminated during the group stage of the Season 3 North American Offline Qualifier for the League of Legends Championship Series (LCS). Azure Gaming and Team MRN proved to be formidable opponents, leading to Team NomNom's elimination.{{cite web|url=http://www.ongamers.com/articles/the-history-and-formation-of-cloud-9-part-1-of-the-cloud-9-story/1100-1302/|title=The history and formation of Cloud 9 – Part 1 of the Cloud 9 story|first=Duncan 'Thorin'|last=Shields|website=OnGamers|publisher=CBS Interactive|date=April 28, 2014|access-date=April 22, 2015|archive-url=https://web.archive.org/web/20150216054323/http://www.ongamers.com/articles/the-history-and-formation-of-cloud-9-part-1-of-the-cloud-9-story/1100-1302/|archive-date=February 16, 2015|url-status=dead}} As a result, Nientonsoh and Yazuki decided to part ways with the team.

In early 2013, Team NomNom underwent a rebranding and officially became Cloud9 (C9).{{cite news |title=Cloud9: An American Revolution – A complete history of the original Cloud9 team, and how they changed the LCS, League of Legends, and esports forever |url=https://www.esportsheaven.com/features/cloud9-an-american-revolution-a-complete-history-of-the-original-cloud9-team-and-how-they-changed-the-lcs-league-of-legends-and-esports-forever/ |access-date=March 18, 2021 |work=Esports Heaven |date=November 23, 2020}} The team's emerged victorious at the 2013 MLG Summer Promotion Qualifiers, defeating Velocity esports in the finals.

The roster, consisting of Balls, Meteos, Hai, Sneaky, and LemonNation, went undefeated in the Summer Promotion Qualifier, earning them a spot in the 2013 NA LCS Summer Split. Following their qualification, Quantic made the decision to revert the team's name back to Cloud9. However, the team would soon experience yet another ownership change, as former Team SoloMid manager Jack Etienne purchased the players' contracts for less than $20,000, solidifying the establishment of the Cloud9 organization.{{cite news |last1=Newcomer |first1=Eric |title=Can this man make his video gaming team a $1 billion business? |url=https://www.bloomberg.com/news/articles/2018-08-06/can-this-man-make-his-video-gaming-team-a-1-billion-business |access-date=March 18, 2021 |work=Bloomberg |date=August 6, 2018}}
