SK Telecom T1 S

SK Telecom T1 S was one half of the dual-roster setup once operated by the SK Telecom T1 organisation in South Korea, competing in the Korean circuit that evolved into the LCK. Now disbanded following the industry-wide move away from sister teams, the S squad forms part of the early history of a brand that would go on to become synonymous with League of Legends success.

Twin Rosters Under One Banner

During the years when Korean organisations were permitted to run more than one team, SK Telecom T1 maintained both an S and a K line-up. This structure gave the organisation a broader footprint in domestic competition and offered a pathway for developing and rotating players across two active rosters. SK Telecom T1 S stood alongside its sister squad as part of an ambitious, resource-rich operation determined to make its mark on the scene.

Life in a Powerhouse Organisation

Being part of the SK Telecom T1 umbrella meant operating under high expectations and within a professional environment backed by significant institutional support. The Korean scene of that period was already establishing itself as the most demanding in the world, and the S team competed amid rivals who set a punishing standard. The experience of playing under such a banner shaped players and contributed to the organisation’s deepening competitive culture.

When Riot Games moved to abolish the sister-team model, rosters like SK Telecom T1 S were phased out as clubs consolidated their talent into single, unified squads. The dissolution closed a distinctive era of Korean esports organisation-building.

A Piece of Dynasty History

SK Telecom T1 S may no longer be active, but it belongs to the origin story of one of the sport’s greatest institutions. Its existence reflects a transitional period in the structure of professional League of Legends, and its place in the record underscores how the modern game’s most celebrated organisation was first constructed across multiple competing rosters.
