Erika Hill, born in the capital of germany, Berlin. She was born into an upper-class family with her father being a sucessful lawyer and her mother being the CEO of a sucessful car business. Since her young age, she was taught discipline and many other things, including many languages, these languages being English, Russian, Japanese (The only reason she learnt Japanese instead of Vietnamese was really just because she despised her parents and refused to learn Vietnamese so she decided to learn Japanese instead as she found that country's culture much better and interesting and also, just to spite her parents.) and Spanish. She never really became fluent with any of these languages until later on in her life, becoming fluent in Japanese and English first at the age of 14 then becoming fluent with Russian at the age of 17 and shortly after, becoming fluent in Spanish at the age of 18. She was taught her entire life how to live the life her parents wanted, especially her mother. In her mothers eyes, there always was one problem with her. The problem being she never enjoyed living this, rich life as a CEO not enjoying her job. She wanted to enjoy her life and wanted to truly live it and not worry about some stupid business she doesn't even care about. At the age of 15, she had attempted to commit suicide due to the amount of stress put upon her and everything that was required of her by her parents, which she felt like they never really cared about her but only their jobs and business.
After Erika reached the age of 19, she had decided to make the decision to leave her parents and live on her own. Refusing to become the next CEO of her mothers' business after her death. Erika never really liked her parents neither did she enjoy living with them and they way they lived. So now, truly being free she had decided to become a Tour Guide. She had lived for 1 year being a Tour Guide mainly in Berlin, still feeling like she is missing out she decided to put her language skills up to use and move out of Germany. The first country she went to was Mexico, spending exactly five years of her life there exploring all the interesting places while also being a tour guide and guiding tours. The last year she had done almost everything she wanted but did not have enough money to continue on with this life, meaning she had to focus more on her job which she did and sucessfuly saved up enough money to move to another country and continue this life-style.
The next country she had decided to go to was actually America! She moved in to Chicago and lived in an apartment for the three years she stayed there, exploring most of the interesting places while still doing her job as a tour guide, living the life to the fullest. During a calm and normal night, she had decided to take a shortcut through a seemingly empty alleyway, unluckily for her, it was NOT empty. As soon as she stepped in, two men popped out from behind a corner with knives, one behind her. She couldn't run and they robbed her, running away after taking all the money she had on her. With weaponry being legal but with a license, she set a new goal for herself. After exactly 145 days, she had received her concealed carry license and sucessfuly bought a Glock 19. Carrying a concealed-carry and going to the shooting range to practice and train with it at least once every week. She was slowly getting bored of Chicago so she made the decision to move to Boston where she happily lived until suddenly, her life shifts.
With her casual day suddenly being interrupted by the Black Mesa Incident and it's consequences with portal storms raging across earth. She hides in her apartment with her recently married husband while this goes on, with windows barricaded and hiding. Watching the television for any news or shelters for them to hide in. Boston luckily being a protection center, they had moved to a shelter that was provided shortly after the beginning of these portal storms. And of course, as we all know the portal storms attract the attention of the Combine.
With the combine occupation happening, Erika and her husband were starving and obviously not enjoying the combine occupation so she made the decision to join the Civil Protection so she may receive the benefits of it, not because she enjoyed it, none of that. She had joined as soon as she could just to provide better food and a better life for both her and her husband. Little did she know that the combine like to relocate, not too long after joining the Civil Protection she and her husband get separated, her being transferred to City 45 from City 16. She was extremely sad about this but during the time she spent as a Civil Protection officer, she found out she actually enjoyed "betraying" her own race and oppressing others, the powers this job gave her. The power and control she lacked as a child and in majority of her life. She kept the ring of her husband but he was not her priority anymore, her priority was to prove herself to others and truly take control of her life. During the time she spent serving in the civil protection, she has been transferred through many cities and actually being happy that she was getting transferred a lot, with there being two reasons behind this. The first reason being that she was hoping to see her husband again and the second reason was that she actually enjoying being in new places. After some quite a lot of time in City 3, she had decided to request a transfer to City 8, either a temporary one or even a permanent one. Due to her being an amazing unit which was dedicated, loyal and disciplined, the Rank Leader decided to 'reward' her with a ""vacation"" to City 8 for around 19 days.
Note: Hope you liked my backstory, put quite a lot of thought + effort into it, sorry if there are some errors in grammar.
