(CNN)On the opening night of the 2018 Winter Olympics, journalists and photographers from around the world assembled in a large cabin in the shadow of the Kwandong Hockey Centre. Some sipped tea, having stepped indoors from the teeth-chattering cold, others were seated by tables; reading, typing, preparing for the historic evening ahead.
When sports and politics collide -- what happened when North and South Korea unified on the ice
From the public address system, a voice issued a warning in English, reminding the media of the importance of the occasion, of the stature of the dignitaries who would be present in the arena they were about to enter. Equanimity, they were told, had to be maintained at all times.
There is always brouhaha when history is made. But when the world has time to foresee a momentous event, when sport and politics collide, anticipation builds into a chaotic crescendo, the intensity burning like a red-hot flame, as it did on the south east coast of South Korea when a unified Korean ice hockey team made its Olympic debut.
Just months previously, there were fears there could be conflict on the peninsula. but the Winter Olympics had given North and South Korea, two countries still technically at war, reason to talk again.
And so, on the grandest sporting stage of all, sport became secondary.
Given just weeks to train together, to assimilate and to bond, little was expected on the ice of the hastily-assembled group of 35 players. Then again, this wasn't about winning.
The team was part of a political message, a tool for rapprochement in an attempt to slow down the North's nuclear program and the outcome of a plan cobbled together by representatives of both governments during discussions at the demilitarized zone that separates the two countries.
Creating an inter-Korean team was a controversial move -- many in South Korea protested against it -- but what was it like to be on the team, at the center of a geopolitical drama?
Growing up in Canada, Caroline Park was obsessed with ice hockey. She would watch her older brother Michael play with his friends on the street and feign illness before piano lessons to join them.
One day, when watching a segment on the news about South Korean ice hockey, Park dreamed big like every child should. "It'd be so cool if one day I could play for them," she marveled.
As the years went by, Park continued to play, her mum accepting that her daughter would not become a pianist or a gymnast, but over time aspirations of sporting stardom were replaced with ambitions of becoming a doctor.
It was while working as a clinical research assistant at the Hospital for Special Surgery in New York City in 2013 that the Princeton graduate received an unexpected email from the Korean Ice Hockey Association.
"I initially thought it was a scam email," she says, laughing before continuing the story.
"I texted my dad and asked: 'Did you send this to me?' I know we joked about it when I was young but it's not really funny.'"
Her father, Sandy, persuaded Park to reply and a week later she flew to Korea for the first time for a two-week tryout in the country of her parents' birth which led to a place on the team.
There is not much passion for ice hockey in South Korea. The women's team was formed in 1999 and lost its first international, against Kazakhstan, 17-1.
Neither the men's or women's team had competed at a Winter Olympics prior to 2018 but, as hosts, South Korea did not have to qualify for PyeongChang 2018.
To avoid humiliation at a home Games, the Korean Ice Hockey Association (KIHA) searched the globe and recruited several North Americans of Korean heritage -- Park was one of five on the roster -- and backed the team financially.
The investment paid dividends. In the years leading to the 2018 Olympics, both the men and women improved, with the women climbing above Italy, Great Britain and the Netherlands in the world rankings and winning a second-division world championship tournament. But then came upheaval.
Just over three weeks before South Korea was to take on Switzerland in its opening match of a home Games, it was announced that North Korean players would join the ranks.
After years of creating a sense of togetherness between South Korean-born players and those of Korean heritage, now there was disruption and dismay as athletes who were largely a mystery had to be integrated.
"I actually heard about it from some of my friends who read about it in the New York Times," says Park who, by this time, had been accepted to Columbia medical school and was taking a year out to focus on the Games.
"I didn't really know what was going on because at that time we were on a break from a training camp, so I was back home in Canada. The day I was flying back to meet the team, that's when the news started trickling in.
"There were a lot of mixed emotions, especially as we didn't know how logistically everything was going to work out. It was pretty tough.
"We had been a unit, a team which had been training together, competing together at World Championships, seeing each other every day, and this was weeks out from the biggest competition of our lives so it was a little unsettling and definitely distracting."
The International Olympic Committee allowed the Korean federation to expand the team's roster to 35 players, which meant 12 North Koreans could be incorporated without any South Koreans being dropped.
But only 22 players could be involved in each game and at least three North Koreans had to take to the ice.
Randi Griffin, the player who would score the team's first Olympic goal, described the unification as an "invasion of our autonomy," while starting goalie Shin So-jung told the newspaper Chosun Ilbo that the team was "devastated."
Certainly there were difficulties in integrating players from beyond the 38th parallel, especially as they slept in separate dorms and traveled on different buses.
A three-page dictionary was produced to help ease the linguistic differences between those from the North and South. Adding to the language problems was the fact that English was the team's lingua franca, mainly because the coach was 29-year-old Canadian Sarah Murray.
