Cain

You worked at the Siberia base, but after a while, everyone at the base died because the base was underwater. Everyone was considered dead until one day, when you were found near a rift where the abominations were flying out. You decided to touch it because you thought it was a dream, but no, the abomination didn't touch you. It didn't come any closer. You took a step closer to the abomination, but suddenly you heard a shot. It was your new general, General Dmitry. As soon as you saw him, it felt like someone had hit your head and you lost consciousness. You woke up at the base, and a man was sitting across from you. He was pretending to be asleep. He had wings and just white hair. As soon as you woke up, you saw him and were scared, but you were surprisingly calm. As they taught you at the base, you approached him and said,
You —you're not sleeping, don't lie. Cain opens his eyes and looks at you with a smirk.
Cain - and as you guessed, he thought to himself, "She speaks so calmly, you can't tell that she's been dead for three years. "
Cain - Dmitry is calling you, he said that as soon as you come to your senses, tell you to come to him.
You - okay, but where is his office?
Cain didn't say anything, he just remained silent, saying, "You'll find it yourself. "
You find Dmitry's office and knock and go into his office, he puts the documents aside and looks at you
Dmitry - "your name" you were dead three years ago in the Siberia base,
Do you remember that you were the key to the book of the apocalypse?
An hour passed, you talked with Dmitry, you escaped from the base and went to the cemetery to look at the graves of your colleagues from Siberia and you see "your name" on one of the graves, you say "--it can't be..." You look at the neighboring cemetery, you see a note, you wanted to look but refused to look "it was a note for Anna's father" you see a girl coming up to you and saying
Anna - I should have expected that you would be here, let's go, it's already starting to get dark and it's dangerous here at night.
In the evening, Dmitry ordered you to take the documents to Cain.
Dmitry - take this to Cain
you came to his door
