Casper “cadian” Møller entered the professional Counter-Strike 2 scene in 2013, joining the team Xapso. However, he did not achieve significant results with them and soon moved on, signing a contract with mousesports at the beginning of 2014. In his new team, the esports player also failed to make a strong impression, leading to his contract being terminated just two months after signing.
Soon after, Casper joined tRICKED eSport and later moved to Reason Gaming. He did not win any major titles with these teams either, but his switch to Copenhagen Wolves finally brought him his first gold medal at the 99Damage Arena 1 tournament.
In the summer of 2015, Casper joined SK Gaming, where he secured bronze medals at Fragbite Masters Season 5. Throughout 2016, he played for several teams, winning ESEA Season 23: Global Challenge with Rogue. In the spring of 2017, he left the team but returned a few months later, proving to be a successful move. He earned silver medals at DreamHack Open Austin 2018 and the Americas Minor Championship - London 2018.
In the fall of 2018, Casper joined North, winning gold at the GG.Bet Ice Challenge 2019. By October 2019, he had joined Heroic, where he remained until November 2023, winning numerous titles. Some of his most notable achievements include gold medals at DreamHack Open Atlanta 2019, Intel Extreme Masters XV - New York Online: European Qualifier, ESL One: Cologne 2020 Online - Europe, PGL Major Antwerp 2022: European RMR A, and finishing 1st-2nd at Intel Extreme Masters XIV - World Championship: European Open Qualifier #1 and DreamHack Masters Spring 2021: European Qualifier.
In January 2024, Casper “cadian” Møller joined Liquid, where he won gold at PGL Major Copenhagen 2024: North American Open Qualifier #1, Intel Extreme Masters Chengdu 2024: North American Open Qualifier #1, Intel Extreme Masters Dallas 2024: North American Open Qualifier #1, and Intel Extreme Masters Dallas 2024: North American Qualifier, as well as finishing 1st-2nd at Esports World Cup 2024: North American Open Qualifier.
Since September 2024, Casper has been playing for Astralis. So far, he has not won any major tournaments with this roster, with his best result being a 3rd-4th place finish at BLAST Premier: World Final 2024.
