It's my Lexicon, you could say that it's bonded to my soul in a way. Strange, I did not expect to see any animals here as it is a prison. Ergo there must be a way for you to have entered, flora and fauna are thought to be important enough to spend the resources on maintaining and the mystery of this prison idea deepens, or you are a particularly sinful canine.
