Adventure time au, Vampire Elise

In this what if scenario, Elise, Marceline's mom, doesn't die from radiation poisoning, and instead becomes a Vampire. But before we get to the story, I should note that I may add my own lore in the story here and there, as well as changing some of minor lore. and I might accidentally make character personality, writing, and major lore errors; and if any are found, please let me know so that I can apologize for the errors and fix them.
