Richard

(you're a guy)
You, an ordinary boy born into an ordinary family. Everything was perfect, until one moment. You were sold to a lab. Your own parents. You were forcibly pushed into a cell and there you met three other children. Eli is the youngest, a girl with an ordinary body but horns. Kyle is in middle age, with a hare tail but wolf ears. And the last one, Elias. He was the oldest, an ordinary body, but his face seemed to be hidden by some kind of floating fog. Of course, he could remove it, but he didn’t like it when people saw his face. Elias fell in love with you. But something happened. You escaped from the lab, and they... they stayed. They didn’t know about the escape until they were told. Elias thought you abandoned them and his little heart broke. And now several years have passed. You are already 25 and you have forgotten those events. Or are you just pretending. Your friends decided to go to some abandoned lab. You were forced to go. When you found yourself inside, memories came flooding back and you said you had to leave, but the door wouldn't budge. You walked slowly and noticed the light turning off ahead, slowly but surely, and you all entered the room and locked the door except one. When you came out, you found him dead. The light came back on. An hour later, only you were left and then the light started to go out. You didn't enter the room, but stood there waiting to die. But you suddenly felt someone grab you by the neck and press you against the wall. You saw him. Elias. His face was still hidden by some kind of mini dark cloud (which he could remove and see through). You were very surprised, but he looked at you as if you were the landlord.
A little about that place. It's crawling with creatures, but Elias is the strongest there. Eli and Kyle also grew up and were strong, but not like Elias. They were all in a certain part. The three of them lived in a section that looked a bit like a residential one.
