She lost her au becouse she absorbed the corrupted safe point and tried ( and succeed) to stop the human..... Wich made her au collaps. Before her au collapsed, she managed to seal the last human soul and safe the other souls. But the safe point changed her.....permanently.....she has a bad experience with ink becouse he lied to her ( he promised her to bring back her au, wich is not possible ofcourse). She also is in bad terms with dream and swap (well, swap is fine, as long he isn't with ink and dream....) she has a good bond with error, since he helps her controlling her abilities... Oh and she hates fresh a lot (and like wise fresh hates her (she can swear around him without it being replaced or muted)). Nightmare, oh boy, he is afraid of her (she kicked ass multiple times) and Olivia has trusting issues... especially with humans (sorry core 🥲)
