A Korean esports organization with a long history. Founded by T1 (formerly SK Telecom T1) in 2002, and was originally a Brood War Orion team. The organization became famous for its StarCraft roster and three-time League of Legends world champion. In 2019, the organization began to expand its activities, and on August 22, they announced that they were ready to create a Dota 2 roster. The first player who joined the team was «Forev», and only in 2020 the team signed four more players, namely, «Meracle», «inYourdreaM», «Jhocam» and «Poloson».
2020 as a whole was not a bad year for the team, given that the roster was constantly changing. This did not stop the team from winning the Hephaestus Cup and SEA Dota Invitational 2020. It is also worth noting that T1 finished 5th in ESL One Thailand 2020: Asia and third in BTS Pro Series Season 4: Southeast Asia. During the year, the team earned about $ 35,000 in total, which is quite good for their level. In late 2020 and early 2021, the team's roster changed, and the old players were replaced by «JaCkky», «Karl», «Kuku», «Xepher», and «Whitemon».
