Quinn "CC&C" Callahan is an American professional Dota 2 player who is currently playing for OpTic Gaming.
Quinn started Dota 2 in December 2012 and later reached 8500 MMR in early 2017 through grinding ranked matches. He was first known playing for FDL for two periods and later played for is GG and Team Freedom for a short duration, later being invited as an analyst for the English talent of the The International 2017. 
Following the International, CCnC was invited by the returning ppd, who was previously in administrative duties with EG, to form a team called The Dire. Shortly after the team's establishment, it was later picked up by OpTic Gaming and on the 16th April, the team won their first tournament at Starladder i-League Invitaional 5. The achievement heralded CCnC's first win in the current circuit season, but also his maiden LAN win in his professional career. 
- CC&C stands for Cool, Calm and Collected.
- In January 2017, CC&C infamously told mason "If your team (Team Onyx) makes a LAN, I'll quit Dota". [Citation needed] Despite mason qualifying for The Kiev Major 2017 as a member of Team Onyx, CC&C did not retire, eventually joining Team Freedom. The two would end up meeting each other in the grand finals of the The International 2017 North America Qualifier, with mason, now a member of Digital Chaos, advancing to The International 2017 following a 3-0 victory.
- Many player transfers during the beginning of the 2017-2018 season were leaked by a Reddit user named LGDamefan. A common allegation was that the account belonged to CCnC. This allegation became so popular, it became a meme and the inspiration behind a BTS skit starring CCnC and Ame.
