Act!

"Psst! Potter!" Quirrel waves Harry into his class after inviting him with a note. It was unusual, unlike how their usual tutoring sessions went.

Harry shuffled into the room and sat opposite the man's desk as he nervously slides into his own chair. "Is something wrong, Professor?"

He nods, "It's time you repay me for your tutelage."

Harry perks up, realising Quirrel was finally making his move for the stone. "Hm? How? If it's something dangerous then I'll have to refuse."

Quirrel forces a smile, "No worries, the task I have in mind for you is more mundane than I'd expected... I need you to distract the Headmaster for, let's say at least twenty minutes. This is very important, Harry, I hate Dumbledore as much as you, and if he manages to keep my stone the magical world could become extremely dangerous for us, extremely quickly."

"How do you want me to distract him? He'll surely realise that something's wrong?"

"Harm a classmate if you must, lead him on with a shallow secret... Anything to keep his attention. Can you do that for me, Harry?"

...

Harry could see Quirrel tenses at the extended silence, probably readying himself to cast the Imperius curse to force his way. He lets out a sigh before nodding, "Okay, I'll do it."

Quirrel finally relaxes and releases the grip on his wand, "I'll make my move in ten minutes, please do your best... Our very lives may depend on it."

-------------------

Harry casts the disillusionment charm on himself and calls Kali to him through their bond. After retrieving her from the Owlery, he takes up a position on the Third Floor corridor, transfiguring a chair and having Kali carve Demonic Runes into it to assure secrecy.

"Is Quirrel moving?" she queries.

He nods, "He asked me to distract the Headmaster, and I decided to allow him to serve as our distraction."

"How devious." she mockingly says with a wing held up to her mouth.

It doesn't take like for Quirrel to arrive, cautiously looking around the place before entering the room... Harry doesn't leave quite yet, continuing to wait until Dumbledore turns up, acting too soon would only benefit Quirrel after all.

Surprisingly, he spotted Neville, Ron, and Hermione sneaking through and entering after Quirrel... He was tempted to intervene as he was sure they were going to die, honestly it would bother him if Hermione met such an ignoble and uneventful end. But he restrained himself and focussed on his and Kali's bond. She was all he needed.

Not long after the trio entered, Dumbledore appeared, rather hurriedly making his way to the door. He couldn't exactly run given his advanced age, but even so, he was surprisingly spry. After he disappeared Harry made his move, making a beeline for the Headmaster's Office.

Sprinting through the castle and up the staircases, he soon finds himself standing before the Stone Gargoyle barring the way to the office. Harry actually doubted he had enough firepower to truly blast it apart, given how strong the wards and charms on the gargoyle itself must be... Luckily, he wouldn't have to try.

"Freddos." he says, using the password Blitzy had managed to overhear.

With a loud creak, the statue moves, revealing the staircase and Dumbledore's Office itself. Harry and Kali immediately get to work, he begins to telekinetically dump all of the books in the room into his bag of holding, then incinerates the Headmaster Portraits that were shouting in outrage at the theft of the unseen criminals.

Harry notes that Dumbledore's Phoenix wasn't present on its perch... Instead, a large pile of ash sat underneath it. Presumably, Quirrel had waited for its burn day, the date that the bird dies and undergoes rebirth, temporarily leaving it powerless.

He, of course, scoops all the remaining ash into his bag. Pheonixes were famous for being able to 'Flame' teleport basically anywhere that wasn't specifically warded for it. They could breach most wards without issue, allowing Dumbledore incredible mobility... Until now. The bird wouldn't be able to recover quickly enough to evade Harry's countermeasures.

"Master! I've found it!" Kali exclaims as she finds the secret switch that revealed a hidden section of the office. There, the duo find Dumbledore's more valuable artifacts, most of which he had no idea what they did.

He did wish the man would've accidentally left the Elder Wand behind in his haste, but he wasn't daft enough to leave it when entering a combat situation. During his search however, he did find a number of things he did know about.

The first is a Pensieve, a large enchanted metallic bowl that you could view memories. You did need to acquire memories before that of course. Even if it served no purpose for him, the thing was too valuable to leave behind, it was probably one of Dumbledore's most expensive possessions.

Next, was a surprising find... An unwrapped but unpacked Christmas present with Harry's name on it, within was a shimmering black cloak with varying grey patterns across it, some making it look like the stars against a night sky.

Harry could immediately tell what this was given the magic he felt from it... He'd seen and been around regular invisibility cloaks before, but none had felt like this... The aura was like a purer, less corrupted sensation that he'd felt from the Lich.

This was a Deathly Hallow, an artifact supposedly created by death, specifically the Cloak of Invisibility... And it had his name on it.

"That old bastard still finds ways to anger me." he growls as he wraps the cloak around himself, proceeding to steal everything else in the room.

"How about we make our anger known, Master?"

Harry grins and ignites flames around his hands, "Let's. I want to see that scheming hypocrite despair at the loss of everything he treasures... Let's burn his bedroom first."

"After you, Master."
