Adaine Abernant is doomed by the narrative. All Oracles are Elves. They always die tragically, it’s said in freshman year. She isn’t going to live forever. She might outlive the bad kids, but she won't live forever. If they live their life expectancy it’ll probably go something like this.
It’ll be Gorgug first, at 75, they all go to the funeral and mourn their beloved friend. Then it’ll be Riz at 80, and Adaine and Fabian will be hit the hardest but everyone will be there, their detective is gone. Kristen will pass next around 80-90, the greatest cleric of her age. The funeral will be in her own church she was working at. Fig, Adaine, and Fabian are the last half that are left. Next will be Fig at around 100-150, the archdevil of rebellion being buried with the feather Ayda gave her at the start of their relationship. Ayda is there, whether in a new incarnation or not we don’t know, but she’s there. Adaine and Fabian are closer than ever, and spend their time together, since Minotaurs live 150 years as well, they likely attend Mazey’s funeral around the same time. Next is Fabian at 180. Aelwyn holds Adaine at the funeral, the bad kids are almost all gone, but at least she has Aelwyn. Then at some point years later, with Adaine, Aelwyn and Ayda all together, Adaine has an accident while doing an oracle-related quest. Aelwyn can’t do magic and eat ice cream with her sister forever. I hope she stays with Ayda. I hope they become a family for each other, since they’re the only two left.
