Olde God of Death

The-Girl-Who-Lived. The-Chosen-One. The-Woman-Who-Conquered. Mistress-of-Death. These were all titles that Hari gained within her life from the Wizarding World. They had time and again worshipped her, reviled her, outcast her, & saw her as a savior. Hari had defeated trolls solved intense (not really) puzzles, saved the philosopher's stone, defeated Voldemort for a 2nd time, been ostracized for speaking a language that's considered dark just because a few bad people spoke it, solved the 50 year old cold case of Moaning Myrtle's murder, found the Chamber of Secrets, killed a Basilisk, destroyed a horcrux (without knowing it was one), saving a first year student from having her life force drained to fuel the resurrection of the Dark Lord Voldemort, survived a werewolf attack, pushed back an army of dementors, defeated a dragon, outmaneuvered merpeople, passed through a deadly maze, witnessed Voldemort's resurrection, defeated Voldemort in a duel, gained "eternal glory", fought Voldemort in the Department of Mysteries, revealed that Voldemort was back, helped defend Hogwarts from Voldemort's Death Eaters, hunted down and destroyed all of Voldemort's horcruxes, gathered the three Deathly Hallows, and killed Voldemort.

Even after all that the Wizarding World expected Hari to bend over backwards to do anything that they wanted, so Hari decided to wander the world never aging, due to collecting the Hallows, and soon she found out about the viral epidemic. The Virus was killing off the human race at a fast pace and there was only a few muggles trying to do anything about making a cure. Hari tried helping the scientists make a cure and when it was obvious that they were getting nowhere, she decided to join another group of scientists that were trying to complete humanities legacy (self-aware robots). Near the ending the scientists realized that since Hari could not die, due to being the Mistress of Death, then they should make sure that she sees their work bear fruit. Hari agreed to connect her mind to the Talos Principle program in order to help the individual AI consciousness to escape the program and walk the earth that its creators left behind. Decades go by while Hari is unconscious until she opens her eyes to look at a clean, clear, unpolluted blue sky laying upon a stone altar.
