Tom Riddle dies, and after 823,543 time-compressed years his soul is pieced back together, whole and complete.
He meets his grim reaper who is pissed because he didn’t fulfil the prophecy. Tom gives him a curious gaze, getting mad at his reaper for making him go through all that, actually having feelings for once in his life and now he wants him to go back!
Reaper explains that the prophecy never actually stated who the Dark Lord was and without him, it would have simply taken on a different form. The Reaper explains how ‘dark’ it must be to wilfully ignore the suffering of children, which the headmasters of Hogwarts have proven time and time again. Riddle scoffs that Albus ‘Leader of the Light’ Dumbledore would ever be dark, but his Reaper explains that the ‘darkness’ can take many forms.
The Reaper tells him that he will never find peace if he doesn’t go back and try to undo the suffering he had caused, especially when he has the means to override the headmasters of Hogwarts as hereditary Guild Leader of Slytherin. He must convince Henry Potter, Eileen Prince and Amalia Bones of Gryffindor, Ravenclaw and Hufflepuff, respectively, to unite the four corners of Hogwarts and defend its students from threats both inside and outside the castle. The Reaper will send him back to his fifth year, before he split his soul for the first time.
Tom is annoyed at first that he has to go back to the orphanage, right in the middle of the second world war, but the Reaper gave him a special task. He must save the life of new-blood student Helen Ambers who would have had a ‘family gift’ of combining electron fields with magical fields i.e. bringing electric magics to magical Britain.
Without her gifts, the magical world had not been able to make similar developments in magic that the muggle world did with science and technology. If allowed to continue, the magical world would be discovered within a century due to magicals being unable to protect itself. The reaper warns him that there are both traditional and progressive forces that do not want to enable the development of 'technomancy' at Hogwarts and would seek to supress this girls’ talents. However, if this girls’ talents are nurtured appropriately, it is possible that the biggest fear (i.e. nuclear weaponry) could be counteracted by a combination of magics, including 'electromancy,' ensuring the safety of the nation.
