As Harry entered the room, he could see the Mirror of Erised and Professor Quirrell. Just as he was about to take another step forward, he swayed as memories assaulted his mind. Memories of another life and the truth. He scowled as he straightened himself out. No longer was he Harry James Potter, but Hadrian Valerian Prince. Hearing voices, Hadrian's scowl turned into a smirk. He walked further into the room and leaned on a pillar with his arms crossed. From there, he could hear Quirrell muttering about how to get the stone out of the mirror. "Need some help?"

Quirrell whipped around at those words, his eyes narrowing upon seeing Hadrian. "Harry Potter. I should've known you would come. After all, you're Dumbledore's precious Golden Boy."

Hadrian scowled at that. "I'm not Dumbledore's anything! Now, do you want my help or not? It does, however, come with certain conditions."

Quirrell stared at Hadrian in confusion. "Let me talk to him," a voice hissed.

"Master, you are not strong enough."

"I have strength enough for this."

Quirrell turned around and unwrapped his turban, revealing Voldemort. "Harry Potter. Why would you help me after what you did to me?"

"I didn't do anything. You attacked a baby that happened to have been your soulmate. Thus your current predicament. Now, I'll ask one last time do you want my help or not?"

For a few minutes, Voldemort was silent. "You mentioned conditions. What are they?"

Hadrian smiled. "First condition is to stop trying to kill me because it will only result in your death due to Magic's punishment. Second condition is to do your resurrection at the end of the school year, preferably after the leaving feast. Third condition is to summon both Snape and Lucius Malfoy right after. Final condition is to absorb all but one of your Horcruxes. I'll help with the ritual." Hadrian quickly held up a hand to stop Voldemort from speaking. "Before you get too upset, know that I am one of your Horcruxes. Now, will you agree or not to those conditions and my help?"

Hadrian could see that Voldemort was struggling with himself. After a few minutes, Voldemort spoke, "What do you get out of helping me?"

"Well, for one I get a sane soulmate, but I also get a chance at revenge. I can't explain everything now, but I will later. Do you agree?"

Voldemort remained silent for a few more minutes before saying, "I agree."

Hadrian smiled. "So mote it be," he said before a snapping sound was heard.

Voldemort stared at him in shock. Noticing this, Hadrian smirked. "You didn't think I would just settle for a plain verbal agreement, did you?" he said, laughing, before looking in the mirror.

After watching his mirror self put the stone in his pocket and feeling its heaviness, Hadrian turned back to Voldemort, reached into his pocket and handed over the stone. "You should probably leave now. Dumbledore should be here soon."

Voldemort nodded and quickly left. Hadrian looked around with a sigh before starting to make the area look like a fight had happened using mainly wandless spells. He only used a few first year spells with his wand as it would be suspicious if there were no spells recorded on his wand after.

After finishing with the area, Hadrian conjured several ropes and turned them to ash to simulate Quirrell's death. Hadrian also conjured a fake stone and broke it. Sighing, Hadrian set up the last bit: himself. Afterwards, he knocked himself out.

Hadrian woke up in the hospital wing to see Dumbledore sitting beside him. Dumbledore then proceeded to tell Hadrian about how his mother's sacrifice and love had saved him down in the mirror room. After Dumbledore left, Madam Pomfrey came over and did a quick scan before telling Hadrian that he could leave.

Hadrian quickly made his way down to the Great Hall and to the Leaving Feast, during which the House Cup was awarded. Once again, Dumbledore gave Gryffindor last minute points that caused them to win.

After the feast, Hadrian rushed up to his dorm and quickly packed everything into his trunk before shrinking it. Hadrian then pulled out his invisibility cloak and snuck into the third year dorms, where he quickly summoned the Marauder's Map. With the map in hand, Hadrian rushed down to the dungeons.

Upon reaching Snape's office, Hadrian knocked and entered after hearing a "come in," from Snape. After he was inside, Hadrian put up the strongest privacy ward he knew before looking at Snape, who looked confused. "Show yourself!" Snape finally shouted out.

Hadrian sighed, removed the cloak, and quickly put it away. Looking back at Snape, Hadrian saw he was sneering. "Potter! What is the meaning of this?!"

When Hadrian didn't respond, Snape scowled. "You are just like your father! Now what are you doing here?"

Hadrian remained silent. Snape quickly got up and started advancing on Hadrian. He was just in arm's reach when Snape's Dark Mark flares causing the Potion Master to cry out in pain and panic. He quickly tried to pass Hadrian while muttering about Him being back and telling Dumbledore. Hadrian frowned before he grabbed Snape and said, "I don't think so, Father," Hadrian then gripped Snape's Dark Mark and hissed, "Morsmordre."

Before Snape could do more than widen his eyes, he and Hadrian vanished from Hogwarts in a cloud of black smoke.
