shortly after being taken from the palace — isis was turned into a vampire by her captor. this, unfortunately, did not bode well for the man who thought to keep her. after the process was complete, isis went into a frenzied state ; effectively killing him in the process. awaking from the state, isis saw the mangled body, the blood on her own, and went into a catatonic state out of fear for what was happening. up until this point she had lived her life as a normal human, with no indication that she was otherwise. this catatonic state lasted anywhere from ~1000-2000 years — most of which she spent sitting in the corner of the room she’d been brought to, or blacked out completely.
when she did snap out of it, isis awoke to an entirely new world. and she was absolutely starving. upon exiting the compound, which was now in the wreckage of a city that once was — isis greeted the new world by killing the first human she saw and draining them. this absolutely horrified her, and she resolved to isolating once more, hoping she would just waste away. but survival brought her back out each time. eventually, isis was able to stomach human food, tolerate the daylight ( without harm, in the beginning it gave her the equivalent of a very very bad sunburn after a few minutes ), and live without blood.
as soon as she realized she was safe to travel amongst humans, isis took advantage of it. by this time it was around 1018 AD. for a while, every move isis made was only to observe and stay in the shadows. she did not want to garner any unwanted attention from anyone — during most of the middle ages, isis spent her time in egypt, relearning her home as it felt like an alien planet compared to the egypt she had left behind. she began collecting artifacts when she could, and to learn the market of the world. isis immersed herself in the tight knit communities, growing close to those often oppressed by society, and began to fight alongside them in history.
because isis was isolated for so long, she spent a long while feeling disconnected from humans. while she was learning about them, and as the centuries moved along slowly becoming more and more prominent in terms of wealth and ability to navigate the modern eras as they passed her by. isis grew closer with humanity, and began to feel like somewhat of a protector of them. for how long she has been on earth, she still has not lost her ability to view humans as good. isis’s view on humans is almost that of a parent watching their kids take steps and fall — still feeling proud overall. of course there are things in history, continuing throughout, to the modern era, that horrify her about humans but isis still has faith that good will win the day.
isis does not isolate herself from humanity like many of her fellow divinities / vampires may — in fact she plays an active role in it. she loves to meet new people, to learn about them, even the most mundane things bring a smile to her face. isis is constantly learning, every person is different and she has had the pleasure of knowing many. while if she does get closer to a person than she usually does, their death will sting, isis is so old now that death is a bittersweet thing to her. the lives of humans are a blink to her, and destroying herself with guilt and sadness over each of their deaths would have blinded her to anything else. so she just tries to enjoy the time she does have with them.
