A place in the first Worlds title
Cyanide was a Finnish jungler who helped Fnatic win the inaugural League of Legends World Championship in 2011, aged just 16.
In its own tribute the same day, LoL Esports recalled that victory and said he remained the youngest player to win Worlds. Fnatic also recognized his four years with the team and the lasting place of his contributions in its history.
