There isn't much known about Gregor's past as he doesn't like to talk about it. What is known though is that before the outbreak Gregor Morowsky was a simple truck driver who was living in Brighton, England. It was always obvious for most people that he wasn't born there. A lot of them could tell it by listening to the way he was talking or behaving. Gregor knew that there was no way for him to hide something like that so he never intended to lie about that part. Originally he was born in Poland but nothing more than that is known. He wasn't fond of talking about what kind of life was there, about his family, friends or hometown. Even if there was someone curious enough to ask, Gregor usually replied that he always wanted to cut ties with his past and he doesn't want to go back to it.
What they don't know is that Gregor was born in not so perfect family. His father was always abusive towards him and barely could find any job while Gregor's mother was always at home. She tried do what was best for her son but in the end she acted like nothing never happened. School wasn't perfect as well. While he had relatively good grades, he also had bad luck finding any friends. Most kids wanted nothing to do with them and some even beaten him up a couple of times. That made Gregor not only aggressive towards his enviroment but also he was hoping for an opportunity to someday leave this "hell on Earth" as he used to call his hometown. Some day such option appeared within his reach but not in a way he imagined. It was a day like any other. Gregor was in his early 20's when he came back home from work. Always wanted to go to university but unfortunately didn't managed. Anyway... it was definitely a day like any other. Mother was doing her own thing while Gregor's father was watching a TV. He forgot a lot of details from that day, even why his dad was angry. What matters is that he wanted to release all those emotions on Gregor yet again since he already finished with his wife before Gregor was back home. It was the same day as many others before... expect for the fact that young Morowsky simply snapped this time. He stood up to his dad and the fight started between those two resulting in a death of his dad. Specifically, he stabbed him to death with a broken bottle of bear. Ironically that was enough for his mother to finally do something. She jumped on Gregor trying to stop him from what he was doing. In the process he killed her as well but this was an accident. It didn't made matters easier for him though. Full of sadness, anger and betrayal, Gregor escaped from his house. He wasn't going to end up in jail because of this. Except for what happened to his mom, he felt like what he has done was justified. In his mind dad deserved what happened to him. In the matter of weeks Gregor fled to England where he managed to change his identity. Why there? Who knows. What's important is that in his opinion it was the best possible outcome for him.
At first he tried to hide but after while Gregor started to look for a job in hopes that maybe there is a posibility for him to start a new life here without anyone knowing who he was and what he has done. Anyway, he was able to find a job as a truck driver in one of the big companies. It was a job which he found pretty much early. Okay, that sounds too optimistic. You want to know what really happened? Gregor was unemployed for almost four months before he was able to get a job. Luckily during those months he made a couple of friends who were willing to help him out a bit. Nice change from what was in home, yes?
As you can imagine he ended up in Chernarus because of his work in the first place. He was on leave, wanted some time for himself away from work when he received a call from his boss that one of the guys got sick and there was no one else available to deliver the cargo. When he finally arrived in Chernarus with what he was delivering, the outbreak hit and he got stuck inside this hellhole. At first he didn't know what was going on exactly. His original destination was the city of Svetlojarsk. One night he decided to stop at some gas station in the middle of nowhere, these days it's hard to remember where he was exactly at this point. Anyway, he stopped, turned off his truck's eninge and decided to get some sleep. A bit after midnight something woke him up. First he thought that maybe it's just a dream or maybe it was nothing or... something. Then he heared this sounds again. Screams, he thought. He exited his vehicle with a flashlight and started looking around trying to wake up from his sleep. His sight was focused on the only vehicle beside his own that was parked on this gas station. Screams were coming out from that direction. Before he could investigate, a gas station staff also took notice of a strange disturbance. All of them approached the car where they discovered three people, two males and female, covered in blood and... eating someone? Shock and disbelief were the first feelings that began to flow through Gregor's head. "I'm definitely dreaming!" he thought. Then those two unknown individuals noticed the small crowd watching them. They rushed at them with growls and opened mouths trying to bite them. They managed to got a hold of a few people while the rest, including Gregor, started to run from them. His first instinct was to jump into his truck and drive as far away from here as possible. He didn't even cared if it was real or not, he wasn't about to be bitten by some crazy junkies or maybe imagination of his asleep mind.
This was his very first encounter with the infection that soon would start to spread across many countries around the globe. After this faithful night Gregor was on the road for the next couple of days jumping from one road block to another. News of some strange disease reached him and he was desperate to find the way out of the country. He was one of those unlucky ones that didn't managed that. By the time he had every opportunity to do so borders around Chernarus were closed basically leaving all of those still in Chernarus to fend for themselves including Gregor himself. Two weeks. Two weeks of craziness, surviving and running from the infected that tried to bite you, eat you. With no way out of this place and nowhere else to go Gregor Morowsky had only one choice. Survive at any cost in hopes that maybe help will arrive soon. If not to end this crisis then maybe to evacuate everyone still trapped here.
Of course, no one knew how bad the situation really was...
