You stumble around in the darkness, there isn't much light at the zoo, only enough to see the glass cages and the name of the exhibits that the glass cages display, eventually you wander and then you wind up in a part of the zoo that looks entirely new, like no one has ever seen it before. this one doesn't look like it has hay or pools or grass or other things that you would usually assoicate with animals. No instead it just looks just plain and modest.
You later see that there is a sign on this glass cage, it says human with unusual characteristics. That's strange, normally zoos only have animals for human observation and entertainment. Why would this zoo have a glass cage and exhibit for a human? And where would they find a Human with unusual characteristics?
