Dumbledore's pov:
I am sitting in my chair eating the new product from honey Duke's and thinking about what Severus told me few minutes ago, he told me he caught Alex in the library's restricted section and send him to patrol with others who are caught by Minerva through Malfoy, my thoughts are on the prophecy appeared almost 12 years ago regarding Alex and the dark lord ,when suddenly I heard heavy foot steps and frowned," who'll visit me at this time and from the sound of the steps it appears the person is in a hurry".
Hagrid appeared in my office slamming the door and saying loudly," headmaster , there is a dark wizard in the forest and he can fire the death curse, he tried to kill Alex with it, but Alex drove him away, you must stop the wizard, he even threatened Alex before turning into black mist and flew away, you gotta do something".
he appeared and shouted these words and not giving me a chance to speak , but after hearing his words a chill ran through my spine then I said," calm down Hagrid, take me to the place of battle and I will find traces there to see what I can do?".
I exited my office along with Hagrid to find Minerva who is should have heard Hagrid's loud voice and appear to be concerned, she also followed us to the forest and we arrived at fighting scene the surroundings all look destroyed and burnt leaving only wisps of smoke and charcoal from trees and craters on the grounds, Minerva looked horrified," oh my merlin! just what is this ?", I didn't say anything but took out his wand and
said," trace reappears", this is a magic used by ministry to find what happened in the scene of investigation and traces of spells along with blurry figures appeares ,but modified by me to also see what happened clearly within an hour.
the scene like time rewind became clear before our eyes and we could see that dark wizard attacking a little unicorn and it's shot by a vicious curse, then just when he is approaching it to Alex and the Weasley's boy
appeared, he hid in bushes ready to ambush them, then Alex came forward and used some kind of magic that nullified the black magic and even spit it out of the unicorn's body and he trapped it in a spherical shield charm all this happened without incantations, seeing this I'm surprised as there is no magic until now in the wizarding world to turn back the effect of black magic known by present generation wizards. Minerva and Hagrid also exclaimed seeing Alex removing black magic from the unicorn and at this time a couple appeared in my mind, tortured by the same black magic and lying in bed lost their brains by it, I thought maybe they could be saved after watching Alex's magic.
then the horror came a death curse shot towards Alex, we all gasped watching this even I'm no exception as even the shielding charm can't protect you until you have special magic provided by a unicorn or pheonix with the shielding charm, but Alex used his magic transfigure the soil near him into an earth wall completely blocking it, seeing this I couldn't help but praise that young man, only a handful of people know how to evade death curse, most think once it's released the person will die surely.
Alex is calm even in this situation and the wizard is threatening him but suddenly there are explosions around him, this is also an unknown magic as the explosion charm only provide a single explosion, and after that Alex transfigured the soil around the wizard again turning them into spikes and the man cast a death curse again ignoring the pain in his body, only to see again blocked by his wall, then the next move even intrigued me, the kid transformed the air around him into needles and blades which are invisible and attacked the man, though the man felt something wrong and placed a protego, it pierced the shield and many needles dug into his skin. which immediately followed by a fire charm and burnt the man before he leaves turning into a black mist, followed by unicorns contract.
Minerva is shocked with the whole duel and Hagrid is in a daze, I only thought there is only a death curse and Alex evaded it, but didn't think a battle this big to happen and most magic used in this is even unknown to me , I'm surprised at the same time concerned about this young man as he might turn into something even far more horrible than voldemort.
Minerva beside couldn't help but ask," Albus, is it really Alex who did this to the man? or are we mistaken?, just what is the magic used in the battle ? and he also signed contract with a unicorn. can this really done by a child of 11 years? the man who attacked him can perform death curse and is on the level of Hogwarts professor's, just who is the dark wizard?" ,I stayed silent and didn't say anything, then asked Hagrid to take care of the forbidden forest and notify me if something happens.
End of pov.
at this moment in a certain office of Hogwarts:
Quirell after duel is arrived to his office and searching for healing potions, he is tattered and covered in blood, at this moment he heard a voice saying go to Snape's office to steal some potions.
Quirell with his bleeding body stole some healing potions and herbs from Snape's office and applied them to himself after a few minutes, his situation is somewhat better and he gritted his teeth from the pain, when he closed his eyes he could see a kid with silver hair beating him with spells he has never seen.
Quirell remembered the horror this kid caused him and shivering from it, voldemort at this moment whispered to Quirell asking who is that little devil, when Quirell told his name to voldemort a shock went through his body and he is begging to forgive him.
voldemort however is thinking about the prophecy, he thought it's false and caught off guard by Lily's magic last and planned to make his come back when he heard about the philosopher stone.
in order to survive he merged his soul with a feeble man he found in Romania with a curse on him, he turned that man into his servant and now in order to survive in this body, he need to drink unicorn blood as this body began to collapse, but didn't expect to encounter the boy again, he is confident in his strength but when confronted by the kid, he is thinkg caught off guard again and swear to bring him down, but deep down there formed a fear within him about this kid and he told quirell to bought the unicorn blood through black market, if not possible kill those and take the blood forcibly.
