Lee "Spirit" Dayun has left Fnatic, the organization announced Wednesday.

"Moving into 2017, we are looking to significantly rebuild our team and the structure of Fnatic League of Legends, whilst Dayun wishes to take on exciting new challenges," the organization stated in a press release. "Therefore, we have mutually agreed to part ways."

Spirit joined Fnatic in December 2015, along with Noh “Gamsu” Yeong-jin. He replaced Kim “Reignover” Yeu-jin on the roster, who had helped the team achieve a perfect, 18-win season in the 2015 EU LCS Summer Split.

However, Fnatic was not able to replicate their incredible 2015 results this year. They placed sixth in the 2016 spring split and fifth in the summer split. They then placed third in the 2016 European Regional Finals, after a 3-0 loss to the Unicorns of Love.

“Working with Dayun for the last year has been an absolute pleasure,” Fnatic manager Finlay “Quaye” Stewart stated in the press release. “Never before have I seen a player with such intense amounts of dedication and attitude towards a single goal of winning. Even after living in a foreign country surrounded by an unusual culture and losing his two closest friends on the team, Spirit gave it his all day in, day out.

“I have no doubt that he has a long future in the League of Legends scene. His jovial personality brings joy and happiness to all those around him, whilst his passion for the game has never dwindled. The Spirit story is far from over.”

Spirit finished the summer split with a 4.69 KDA, around average for EU junglers that season. According to Oracle’s Elixir, Spirit also maintained a 19.1 percent death share, the lowest in the league, though he also had the lowest first blood rate of any jungler in Europe that season.
