Years have come and gone again, but for those who live for centuries, a year is but a blink of an eye.
Without a thought, Perseus had accepted the price they had to pay from Lady Hecate. At first, nothing seemed wrong, but after their twenty-fourth birthday, they stopped aging. It wasn't noticeable at first, but years passed and people started to look suspicious at them.
One day, they were cornered in the Ministry, surrounded by the Aurors, Madame Bones tried to stop them, but it didn't work. Perseus and Hadrian probably would have died that day if it was not for the sudden appearance of Lady Hecate, who claimed Perseus and Hadrian as her champions to rule and take care of the Wizarding World. After that, they had no problems at all changing the Wizarding World for the better.
Years past and Hogwarts flourished again. New subjects were introduced and old subjects were updated. Hadrian stayed as Headmaster with as Deputy Headmaster Perseus. Together they made sure that the Houses were able to interact with each other without any fights. When seven years had passed, with only the new students, almost no rivalry existed. Hadrian and Perseus were proud about that fact.
Minerva McGonagall didn't stay as Head of Gryffindor, for Hadrian didn't thought that she was good enough for the students, but she did stay as teacher.
Severus Snape was fired but had his own shop in de Diagon Alley where he sold potions and ingredients.
Lucius Malfoy was a very helpful hand to change Hogwarts and the Ministry.
Madame Bones had a handful with her Aurors and trying to level them up before becoming the Minister.
It was through the memories of Dumbledore, that Barty Crouch Jr. was found out and killed. They also found all the Horcruxes and destroyed them. Voldemort never came back.
Rita Skeeter got fired at the Daily Prophet and put into Azkaban after she published a harmful article about Hadrian. The day after that, she was found out as an Animagus. Nobody ever saw that link. Perseus just chuckled.
The Dementors in Azkaban were destroyed after forty years, because they were going rough and the only way to stop them was by destroying them.
Most of the creatures were welcomed back in the Wizarding World and stood side by side with Wizards for the years still to come.
Hadrian started living with his Godfather in Grimmauld place. After one day, he gave it up and called Perseus. After that, Perseus lived with them again.
As for Perseus, sometimes he got an order from the gods, but that was the only thing that he heard from America. He never heard again from his mother or his old friends.
It was only after centuries had passed, that Hadrian and Perseus finally passed away, side by side. They had lived their life to the fullest and didn't regret one thing. And don't pity them. Don't pity the death, pity the living, for they will have to live without their loved ones.
