He was a cool character. I did have stuff planned for that maze, but I realised it was going to be ages (in real time) before I could make it happen and even longer before it could become relevant to the story. The group was eventually going to be hired to investigate you, so you'd be investigating yourself and eventually you might even have caught one of your team mates.
However, most of this stuff sounds really cool (to me, at least), but ends up very difficult to work into a plan. If I were ever to run another game of this kind, it'd most likely be in a different system, among other big changes. Maybe even world of darkness. Anything else of this sort would be a way off though.
