BD, or "Black Death" as The Fool
They have such an amazing backstory was written for her I am just going to copy and paste what they've said:
"she is something between a zombie and a ghost, another kind of monster, simply called "the undead". People like her maintain most of their appereance, from before death. The twist is, that the scars from what had killed them remain. This happens to ghosts as well, but people who reach the "eternal happiness" and don't appear back in human world look exactly as they did in the happiest moment of their life. Basically they might have died at 90 but in their afterlife, they will appear 20. Now what makes the undead stay on earth? Unfinished business. But it's not exactly things they didn't get to finish in their lifetime. Going by this logic, 99% of people would have had to come back from the other side. This unfinished business is more about self-fulfilment. And this is when we get back to BD. She was very young when she died, so naturally, she didn't do everything she wanted in her life. But what keeps her bound to Earth is the fact, that she never actually got to be a child. Living in 1340s, it was expected from her to act like a adult from the very beggining and to top it all of, she came from a very rich family. Now it has been hundreds of years, but some MYSTERIOUS FORCES brought her back from the other side around 1950s. She spent so much time dead, that she doesn't even remebmer who she used to be. That's why she uses a name based on the plague, that caused her demise."
The Fool card is BD's because The Fool represents a new journey, the begining of something new. Now BD is on her way to discovering how to be a child... What better character to start off with than a spooky zombie child who just wants to have fun?? ;)
