However, I just posted a question on the thread about how it was implemented. The Death and Quarseta-ql-Paneu keys were combined which seems weird. Also she was given Concept Manip/Life Manip which weren't on your profile, so idk how valid those additions are.
If we take her being Death as literally being the concept of death, then yeah, she should have Abstract Existence. I didn't add that to mine because I didn't want to jump into conclusions, but it is a valid interpretation.
I'm not sure which type of abstraction she would be, however. Back when I made the page, Abstract Existence didn't have different types, it was only one thing.
