Originally within Chernarus for a musicians gathering alongside her partner in music, Coven Finnish, who was the lead DJ Mixer for the group. Cyn and company were locked within the airport while it was on shutdown when the infected started appearing. She kept the spirits high for the people withing the airport by playing guitar and teaching others how to, trying to boost morale. By the time they were let out, it was too late to fly out back to England to reunite with their families due to the no fly zone pass and the buildup of people within exit checkpoints.
As they were leaving the airport, Coven was taken down by a crazed infected and Cyn oversaw the gory mess that was the kill, she overtook it with her guitar, bashing it in and ultimately destroying both the guitar and the infected, but Coven didn't make it. The infected started to grow in numbers and overtake big cities such as Cherno and Elektro, and Cyn found solace helping some of the survivors make it to the countryside for safety, all while looking after her own well being.
Cyn seems to be kind hearted, and not very bias towards dilemmas, she approaches things level headed and tries to reason out rather than fight- unless need be or it absolutely calls for it. She is disgusted by eating and drinking noises alongside infected gargling and seems to make a comment about it or scoff when it is heard.
