It was an ordinary day, you were playing Minecraft, but suddenly a box appeared in front of you. When you clicked on it, a yellow round ball with a smiling emoji face popped out. He introduced himself to you
My name is Verity, I am your assistant. I know everything, just ask.
You started hanging out with him; you built a house and a base a bit further away from the house, up on a mountain. Everything was fine, Verity helped you around the world, telling you where to find things. One evening, he started smiling strangely, and you decided to ask him
You: Verity, is there something I need to know?
Verity looked at you with that creepy smile and answered
Something is coming in three days.
You didn't understand and felt a bit uneasy. The next day, you locked Verity in the house and left for the base. He shouted after you
Verity: You are mine, you won't leave, I know where your base is.
Towards nightfall, you heard the song that Verity used to play for you, and the thought flashed through your mind: "How did he get out?" You decided to go down and check, and suddenly you noticed a terrifying, long, yellow creature. It suddenly rushed at you; you quickly climbed back up and entered the base, blocking the door. But when you turned around, the creature was there—it had smashed through the glass. You quickly ran out and bolted back to the house. Once inside, you rushed to the second floor and blocked the stairwell, only to see a faceless Verity—the rest is up to you)
