Quirrell, Potter, and the Ritual

The next day, I find myself back inside the ROR.

I plan to banish the soul on Quirrell's head, kidnap Potter, stole the invisibility cloak, and do the ritual.

In the evening while everyone is having dinner, I wait for the Weasley twin and Potter near the Gryffindor common room. Not long after, they appear at different times. I imperioed Potter to go to the seventh floor in an hour with his invisibility cloak and to pretend asleep in the meantime. The Weasleys, I imperioed them to give me the Marauder's Map which they bring at that moment. A few seconds later, I am off with the Marauder's Map.

Seeing on the Map, Quirrell is inside his room. So, I go there.

With my advanced warding techniques, I ward his room from the outside so the person inside can't apparate, disapparate, make noises, use magic, and ask for any help. The wraith will also be blocked from escaping. Wasting no time, I chant the soul banishing ritual for 5 minutes straight. A tremor of magic later and waiting for another 5 minutes, I cancel the ward and get inside the room.

Quirrell is dead on the floor. There is a scorching mark on the floor where the back of his head contacts the floor. The wraith is gone. My job is done. I go to the seventh floor to wait for Potter.

Thirty minutes later, Potter come. I take the invisibility cloak and remove all the tracking spells. Then I hold his hand and we both get inside ROR, then to the Black Manor through the vanishing cabinet.

Inside the ritual room, I order him to lie down on the floor inside a circle with other Horcruxes. There are 5 of them: locket, ring, cup, diadem, and Potter. The process is quick and quite painful for Potter. In 10 minutes, all of them are Horcrux-free.

Potter is still unconscious. I ask Kreacher to feed him some super growth, nutrition, and eye potions that will restore all his strengths and growth, and heal his eyesight instantly. I also give him a bundle of letters that explains the ritual I had done on him, his position in the magical world, to not trust others blindly, to question every motive, and to study his heritage as the last remaining Potter. I also give him my other invisibility cloak as replacement.

After he woke up, I imperioed him to go back to Hogwarts and cancel the spell after he's at Hogwarts.

All done.
