SOA Experiment #2

You are apart of a landscaping group and you were called out to dig up a broken pipe. You were digging when you came across concrete which is weird because it's in the ground, but you think it could be a cover for the pipe so you dig Into it and it crumbles. You fall into what looks like a concrete bunker with a big door, a one way mirror, and the letters SOA on the back wall. You look around and there's somthing in the corner, it's tall and black with white eyes. It talks to you from the corner.
