I don't own Harry Potter minus my OCs, enjoy.

After Tom finished telling the origins of Halloween, the students were heading out of the castle when Harrison and Liza appeared in front of the entrance. The female students started whispering and blushing.

Harrison smirked, "Starting without us?"

"Of course not, father. We're just waiting for the others," replied Tom.

"Give me a few minutes. Your mother will be guiding the night students," said Harrison.

Tom nodded and within minutes, everyone started to show up.

He then placed his wand near his throat, "Attention students! Now, let us discuss the rules. First year students to fifth years, you will be assigned to two professors to make sure you are safe – DO NOT wander off! Sixth and seventh years, while you are allowed to be on your own, the other professors will keep an eye on you."

Harry could tell that Roni was mentally cursing cause she wasn't allowed to go on her own.

"You will LISTEN to your assigned professors, if you misbehave, there will be consequences either a detention, loss of house points or both. If any danger comes, no matter what, all students head inside to a nearby shop – DO NOT LEAVE until it's safe. Are we clear?"

The students nodded.

"Good, now your assigned professors…"

The first and second years were assigned to Professor Phoenix and Harrison, who finished upgrading the wards.

Third and fourth years were assigned to Minerva and Salazar who was dressed as a muggle officer including his wife, Bellatrix.

Lastly, fifth years were assigned to Lily and Petunia.

"Aw, your sister is adorable Harry," squealed Hermione.

Iris was dressed in a blue uniform and wore a yellow hat. Meanwhile, Avalon who was dressed as Wonder Woman was handing Roni the fake sword.

"But mine's the best," boosted Hydra before roaring at random students. Mary who was dressed as Mary Jane ran after her only child.

Serenity's eyes twitched, "Annoying little brat…"

"He's just a kid, leave him be," said Leonard.

"How do I look?" Pandora asked.

"Adorable. You even have the white rabbit's watch," replied Hermione.

Pandora grinned before smirking at Roni, "Mummy said you need to watch me while she and daddy are working. No whining."

"Well, at least I don't have to babysit Griffin as well," murmured Roni as they got into the horseless carriages.

"Harry, what type of horse is pulling the carriages?" Iris asked.

"Horse? I thought these carriages were being pulled by magic," said Hermione.

"No, they're not. It's a dark skeleton horse called Thestral, but you can't see them," replied Harry.

"Oh, that's sad," said Iris.

"Yea! What if someone wants to pet them? They need love too!" Pandora said.

"Don't worry, they get plenty. Hagrid and the night students make sure of it," assured Bertie.

Pandora and Iris smiled.

"So, what's the game plan?" Draco asked.

"Well, for sure we need to go to Honeydukes and Zonko's," said Leonard.

"But we don't know what they are going to give out," said Bertie.

"Well, we can all guess, but no matter what, it's free stuff," said Skylar.

Harry and the others just grinned.

-Hogsmeade-

"Oh! All of you look so adorable! Never would I thought I would be doing this 'trick-or-treat' thing," said Flume's wife. "Well, here you go, enjoy! Come again!"

Roni's and Draco's eyes brighten upon seeing the bag full of sweets. Harry and Skylar shook their heads before heading over to the next shop.

"Oi, have you notice that the Fifth years are going to Madam Puddifoot's tea shop or Hog's Head pub?" Leonard pointed out.

"I guess they're hoping to get a free drink or something," murmured Draco.

Hermione's eyes brighten, "Let's head to the Quill shop! Maybe Scrivenshaft's handing out free quills and stationeries!"

"Sure, why not," said Harry. "Granddad, may we go to the Quill shop next?"

Harrison could see most of the second years frowned. "Right, who wants to go to the Quill shop?" The first years raised their hands.

"Zonko's Joke shop?" All the second years raised their hands.

"Right, Professor Phoenix take the second years to Zonko's while I take the first years to Scrivenshaft's Quill shop."

"I don't mind taking the first years to the Quill shop," said Phoenix.

"No, it's quite alright," said Harrison.

Phoenix nodded, slowly and guided the second-year students to the joke shop.

Harrison and the first-year students and two young children headed to the quill shop where he spotted James and Sirius who was dressed as Spiderman.

As the students were getting free quills and stationaries, Harrison walked over to them.

"Go to Zonko's. Inform me if you don't see Phoenix with the second years."

James and Sirius nodded and headed towards Zonko's.

"Look grandpa! The shop owner gave us Phoenix feather quills! Mine's from a Wind Phoenix!" Iris said, happily as she held up a light green and white feather.

Harrison smiled, "Well, take good care of it. It's rare to find an element Phoenix who willingly hand over their feathers."

Iris nodded and placed her new quill in a box then in her bag.

"How many elemental Phoenixes are there, grandpa?" Pandora asked, looking at her bright pink feather quill.

"There's quite a few, but they're hidden. Dark wizards wanted them for their tears and feathers," explained Harrison. "But there's a sacred place for them which is heavily protected."

"Like the dragons! My sister Charlie works with them in Romania!" Roni said.

"Exactly. Now, next stop…."

Harrison stopped upon seeing James' Patronus appear in front of him. The first years were in awe upon seeing the stag as the patronus replied with a message.

"Phoenix out of sight! Phoenix out of sight!"

Harrison gritted his teeth as the stag faded away. He turned around to the first years, "Head to Zonko's and stay close."

The first years were tensed upon feeling the dark aura coming from Harrison but calmed down when they saw the joke shop.

When they reached the shop, James and Sirius were with the second-year students, who couldn't find Professor Phoenix.

"Grandfather, where's Professor Phoenix? He was here not too long ago," said Leonard.

Harrison shook his head, "I'm not sure. Why don't you all head to the Quill shop with Professor Potter and Mr. Black? Stay with them until further notice."

Leonard, Bertie, Serenity and the other second-year students nodded and followed James and Sirius to the Quill shop.

As Zonko was handing out free joke products, Iris started to squirm. She pulled her brothers robes, "Harry…Harry!"

"What's wrong, Iris?"

"I have to go," whispered Iris.

"Alright, come on," said Harry, grabbing his sister's hand. After telling his grandfather where they were heading, he and Iris dashed to the loo where Zonko pointed out.

Waiting for his sister, Harry leaned on the wall and looked at his bag of goodies. Sure, it wasn't a lot, but Flume's wife did give them a lot of sweets and the feather he got was black and white.

'I wonder if there's a Shadow Phoenix,' Harry thought.

Suddenly, he saw something from the far corner. Harry was curious on what it was, but he couldn't wander off. He knows he'll be in big trouble if he does.

"I'm done!" Iris said, leaving the bathroom. That's when she noticed her brother was looking at something. "What are you looking at, Harry?"

"Um – Oh! Nothing. Let's head back," said Harry.

As they were about to leave, the Potter's pendant started to warm up. Harry widened his eyes before pulling his sister to his chest and dropped to the ground, quickly.

Harry shielded his sister from the fallen joke products as a red spell hit a shelf nearby. The eleven-year-old was about to get out when he spotted an elderly man came out from the back.

"Damn. And here I thought this was going to be easy – come out, boy! If you don't…well, it wouldn't be pretty for your bratty sister!"

"Ry, I'm scared," whispered Iris, nervously.

Harry sighed, "Try to stay calm. Look, I'm going to distract him while you go get grandpa."

Iris shook her head, holding her brother's arm tightly.

"I'm going to be fine. I just need you safe," said Harry.

"A-And you?" Iris sniffed.

Harry took out his pendant, "See this. This will protect me."

Iris bit her lip, "…O-Okay…"

Meanwhile, Harrison was waiting for Harry and his sister to return, but it was taking a bit long. That's when he spots Iris running to him.

"Iris, what happened?" he asked, seeing Iris' costume in a mess.

"Someone attacked us! Ry told me to come and get you," sobbed Iris.

Harrison gritted his teeth, "Right – Zonko, take the children somewhere safe!"

Zonko nodded, "At your service, Minister. Come on children, to the second floor."

Iris, Pandora, and the first-year students went upstairs with Zonko. Once everyone was upstairs, Harrison casted a protection charm around the store…just in case. Slowly, he walked to the back and heard Gilbert's voice.

Harrison hid behind some shelves and peeked to see Gilbert and Albus.

"Damn it! Find him, quick Albus!" Gilbert cursed, clutching his new wand.

"Child…you're making this quite…difficult," said Albus as he was walking around. That's when he heard a small noise and pointed his wand to his left. "Bombarda!"

Harry ducked as a blue shield appeared around him and avoided the falling joke products.

"Come out, brat!" Gilbert smirked, "If you come willingly, I wouldn't hurt ya brat sister…"

"Like I will allow that – Alarte Ascendare!"

Albus and Gilbert were blasted away like a cannon. The two elder wizards quickly got up and Gilbert cast the Arrow Blaster to Harrison's direction.

"Albus! Get the brat…I'll deal with this bastard!" Gilbert shouted.

Albus nodded, but as he was about to find the boy, he couldn't move. He looked around and heard an all-too-familiar giggle coming from the shadows. Albus turned his head to see Yuki appearing from the shadows and was sitting like she was on a chair.

Yuki glared at him, "Do you really think I'll let you get my great grandchild, Dumbles?"

Albus gritted his teeth before casting the counter curse of Colloshoo and started casting Lacarnum Inflamarae at Yuki's direction.

While the four were dueling, Harry took his chance to get away from the chaos, but a few stray spells almost hit him. He looked around, trying to find a way out when a stray stun spell hit him and sent him backwards to some shelves.

The young wizard was unconscious as he fell to the ground.

No one noticed, minus Aiden who appeared by his side and apparate out of the room. He made sure Harry was healed before casting rennervate on his young cousin.

"Wha…Where – Aiden!" Harry said. He looked around and noticed they were at the entrance of the store. "How…did we get here?"

"Do you really need to ask, little cousin?" Aiden smirked, sarcastically. He then turned serious, "You and the others go somewhere else. I'm going to help dad and grandma."

"…just be careful…something is wrong about them," murmured Harry.

"I will, come on," said Aiden, taking Harry upstairs. He told Zonko to take the children to Honeydukes where there is a hidden passage to Hogwarts.

The shopkeeper nodded and guided the terrified first year students and the two children out of the store. Once they were far from it, Aiden went back to help his father and grandmother.
