Erik's mom Vera Skala came to Finland for a better payment. She worked as a cleaning lady and married a Finnish man Juhani Koivu. They lived in Kouvola when Erik was born. He was a good kid and was always into sports. At the age of 10 he got a little sister, Elena. Their parents divorced a few years later and Vera moved back to Chernarus. During the Chernarussian civil war many relatives of Erik died and he didn't really travel much to see his mom. He was always worried about her, but she made it out of the war unharmed. When the other kids were starting to smoke and drink alcohol, Erik focused in track and field. He went to the high school and went through it with pretty good grades. At the age of 19 he did his conscription in the Finnish defense forces as a recon radioman. He enjoyed his service, as he was doing pretty good. He learned the morse code and good survival and stealth skills. He later attended some repetition training afterwards. After that applied to a university of a technology and started to study mechanical engineering. He is a native Finn, but he is half Chernarussian. He spent some summers in english language summer camps near Khelm, where his grandfather lived. He knows some Chernarussian phrases, but can't remember anything more complex.
In the days before the infection Erik and Elena traveled to Chernarus as their grandfather celebrated his 80th birthday. They met their mom and went to the house of their Grandpa Alexej. Things went down and Erik was left only with his sister Elena. Now both of them are trying to survive together. He doesn't know where his cousine Robert is, but rest of the family that attended the fest, are dead. He is devastated from all the losses, but tries to cheer Elena up anyways.
-Update 1: Robert came back after a few weeks and Erik left Elena with him, as he went to gather supplies and information. He teamed up with a soldier named George and has been surviving around Chernogorsk since. Both of them have been scavenging the nearby cities and villages for useful supplies and even found a couple automatic guns. On one trip, when they got seperated, Erik was trapped inside a house, while a huge pack of wolves was howling outside. He managed to kill over 10 of them and the rest ran away. He only got some minor injuries, as the wolves couldn't get inside the house. He also met a friendly survivor Baz, whom with they went fishing a few times.
-Update 2: A year has passed and Erik never found Elena nor Robert. The House were he left them was raided by unknown people and there is barely anything left there. By this time he has lost hope that he will find his little sister any more. It has taken a toll on him an the once happy and optimistic Erik is now facing the reality that the society is lost and all he has left is himself. He has bonded with people every now and them, but he knows that people come and go.
He also has tried to settle down in Cherno, but the increasing amount of infected worries him.
