Bound to you~skyrim

This is hard to explain.
This world, it's based on a game.
One of the biggest skyrim fans bought the rights to the game, bought a continent, and built the geography of skyrim on this land.
Of course it helped to have been extremely wealthy and had the money and connections to do all this.
After several years, it was opened.
Anyone could come and explore this land, mine, Hunt, buy property, even become thane or achieve other titles.
But this land is considered it's own country, which includes the laws.
Of course there are no dragons or magic, or any thing of the sort, except the founder used his great wealth to hire people to create item similar to the game.
They found a way to make healing potions, (doesn't function exactly as in a game, but it can cause a short burst in regeneration of cells, etc.) but they also made the less desirable things from the game, like vampirism, (again, no magic, so it is spread through biting, and 'vampire seduction' is more like a paralyzing agent)
but this story is not about the creator, it is about an unlikely encounter and an odd relationship between two girls who are engaged in this dangerous realm.
One is a huge fan of the game, and is also smart, polight, and just advanced in many skills. She's also advanced in sarcasm and stubbornness.
And so is the other girl, but we'll talk more about her in the book. Let's begin!
