Cemeteries have always been a great place for friends to hangout, lovers to express their undying love, Pokemon hunters to meet their quota, and people who need to be close to the dead to understand the living.
This story is inspired by one of my night hikes during my scouting days. One of the things we had to do was to retrieve a cryptic message posted on the far end of the cemetery on a full-sized cross. Although we laughed about it none of us wanted to go in when we reached the entrance to the memorial. There was a bit of an argument as to who should be the hero to trespass on the dead until someone sacrificed himself for the good of the patrol. Everyone survived.
This scenario sets the mood of the beginning at the story and the rest are cooked up in my cauldron of cataclysmic darkness.
