The Psychopomp and the Angel of Death

To begin with, I was dead and had been for half a century. My name's Zann (short for Susana). I was twenty years old when I died, and I was still here. I'd started out thinking I was a ghost or wraith, just popping up at death, but then things got complicated. I started helping others go to the Afterlife, which, I guess, makes me a psychopomp. My helping souls go into the light did not set well with the Angel of Death.
He's supposed to get stubborn spirits like me to move on. I haven't, which irritates him to no end. I was convinced modern technology would soon make hiding the supernatural impossible. Not everyone wanted to be outed. After I argued for coming out, the pantheons got involved. Then, things got really complicated.
