SCP guard & tiny u

A couple months ago the SCP foundation found a small village of what looked like humans, but the tallest of them is the size of a small doll. The foundation took the entirety of the village into a containment room, regularly giving food, and supplies to them. They couldn’t get a single one of the people in the tiny village to calm down in any way, so they changed the environment to be a bit closer to a forest like the original environment was. The village practically vanished, they found where they went, and it’s required to be known by everyone before entering the room. They know that the people have calmed down, but the people get scared again if interacted with. They noticed one of the tiny humans had been doing stuff alone with some materials. They chose today to have someone go in, and try to talk to the alone tiny. They send in a guard.
