Tinkering with Necromancy

I was some kind of wealthy person expected to attend dinner parties, etc, but I decided that wasn't for me so I needed a new career. I could choose between tinker, gypsy or prostitute. I decided on tinker as they had started a small musical band and were more respected than the gypsy group. One of the girls was kidnapped and taken into a haunted house and as part of my initiation I had to get her back. I had to defeat all the undead things and I worked out there was a chant that had to be performed on a certain design on the floor which included a pentagram and "666". After we defeated the spirit necromancer he told us that this was only the beginning or "part 1" and he would return again stronger.
