Personally it was before I even joined the institute. I joined because I thought they did more to try to track down the monsters of the world. There was something I was hoping to find and also learn a way to kill.

Except it wasn't really anything like that. It was like any other desk job until these worms started to show up. At first that's all they were. Just really weird worms to be careful around until they started stalking people. It just got worse from there.
