"Are we sure about this, Harry?" whispered Mr. Weasley as Mr. Potter and I followed him through a lush forest. Wands at the ready. "Allowing a student on this mission? It could be dangerous."

"You didn't say that ten years ago." Mr. Potter said smiling.

"Yes, it was fun and exciting, but I'm a retired man now. I'm only doing this because Hermoine didn't want you to be alone."

"I'm not alone, I have my apprentice."

"Who's a student." Mr. Weasley noted.

"Miss Smith is a very capable and talented young witch." Mr. Potter said to his friend with confidence. "I believe we will have more of a chance apprehending Liam and his followers with her. I asked Professor McGonagall to look for a student who is proficient in the dark arts and would be interested in being an auror. She recommended Celestia and gave her special permission to miss the first two months of her seventh year for this mission as special auror training."

"I'm sorry did you say, Smith?" Mr. Weasley stopped in his tracks and turned around then pointed his wand at me. The Lumos charm from his wand blinded me.

"Yes," I said squinting. "Celestia Smith. It's a pleasure to meet you Mr. Weasley. My father has told me all about you." I held out my hand to give him a hand shake but didn't return the gesture.

Mr. Weasley's eyes narrowed. "Your father?"

"Zacheriah Smith, sir." I replied. "He-" I stuttered out. "He was part of Dumbledore's army with you and Mr. Potter during the second wizarding war."

"Zach Smith," Mr. Weasley said my father's name with vile as he swiftly shifted his gaze from me to Mr. Potter with annoyance. "Are you telling me that disloyal git's daughter was recommend to help us out tonight?! Do you not remember that night?!"

"Ron," said Mr. Potter calmly. "we can't blame Celestia for her father's mistakes."

"He didn't believe Dumbledore about Cedric's death. He questioned your expertise in defense against the dark arts. He didn't attend Dumbledore's funeral. Worst of all, during the war pushed out frankie first years out of his way instead of defending them or helping them out! Oh, I feel so much better with his flakey spawn having my back tonight."

I drooped my head in silence and gripped my wand in hand. Yes, as much as I hated want to admit. My father was a coward and the most disloyal Hufflepuff wizard in our history. Every since I started my years at Hogwarts, I've been teased, ridiculed, and outcasted, by my house and peers for six long years. Which should be impossible, since Hufflepuffs are suppose to be kind to all despite their background, right? Or so I thought.

I can recall the whispers behind my back whenever I walked around the castle ground. I can recall the name calling like coward and disloyal along with more foul words I best not speak. All because I was Zach's Smith daughter. The only friend-best friend I had was a boy from Slytherin, but later that fell apart when he was seduced by Liam as many were over the past two years.

With a broken heart, I vowed I'd restore the Smith name to it's former glory and honor as a descent of Helga Hufflepuff. More importantly, I'd save my friend. What better way to restore it and find my friend fast enough than becoming an auror?

"Ron," Mr. Potter began to say in a harsh tone as I felt his stare on me.

"You have every right to dislike my father, Mr. Weasley." I said, cutting Mr. Potter off. I slowly raised my head and looked at Mr. Weasley in his blue eyes. "He betrayed you all when you thought he had your back during a dire time, but believe me when I say this, Mr. Weasley. I am nothing like my father. I am member of the Hufflepuff House and the last descendant of Helga Hufflepuff. I'm loyal to the ministry and has worked worked extremely hard to get where I am today. I would never ever betray any of my auror comrades in battle, or anyone for the matter. I have no trouble dying for someone if it means there safety."

Mr. Weasley remained silent for a moment. Then said in a huff, "We'll see." He turned on his heal and continued forward into the bleakness of the fogged forest.

Mr. Harry Potter clasped my shoulder with his hand. "I believe you, Miss Smith. After mentoring you for less than two months, I can see what Professor McGonagall saw in you."

"And what is that, sir?"

"Potential. Now, let us hurry. We can't let Liam Byrne and his followers get away. "

I nodded. "Ready when you are, sir."

Mr. Potter gave me a slight nod and started to catch up to Mr. Weasley.

I know very little about the latest dark wizard. His name is Liam Byrne. He graduated from Hogwarts two years ahead of me, well technically one since I skipped my second year. He was a Ravenclaw alumni and was said to be a genius in the art of experimentation and charm usage. Professor Slughorn once said in potions class that he could be the next famous wizard to create a new potion or magical object that will greatly benefit the Wizarding Community around the globe.

Unfortunately, Liam Bryan had other plans for the Wizarding Community and worse of all, his family were former death eaters. Over the last twenty years since the battle for Hogwarts, a few death eaters and followers of Voldemort have been regrouping in the shadows.

A most recent attempt was the arrest of Mr. Theodore Nott just a year ago. A man who had hoarded various magical items over decades and didn't register them. The Ministry raided most of his objects including the last time turner, but has forgotten to take in possession of a mysterious, powerful, stone like orb. No, it wasn't the infamous resurrecting stone, but something else. Apparently, Nott has sold Bryan this object prior to his arrest then Bryan summoned whatever followers were left for one last rematch against the world.

For two years, Bryan's terror has reached Europe and MACUSA. His followers call him the 'Next Voldemort'. The only reason people are following him because he promises them anything they want. I don't know for sure if he has kept those promises, but whatever Byrne's true reason it wasn't good.

When we made it out of the edge of the forest, we saw a massive cliffside beyond a grassy clearing and on a small hilltop was an old crumbled watchtower. I also noticed we were close to the seaside. I could smell the hint of saltwater in the air.

"Look at that stairs," Mr. Potter said pointing at some stone stairs that led to the very top of the watchtower with his wand. "I bet Bryne is up there."

"Alright," said Mr. Weasley gripping his wand tighter. "we should apparte to the top of the cliffside and stun the dark wizards quickly. Looks like he hasn't started the ritual just yet, so we still have a chance to stopping his operation."

I blinked. "Ritual? What ritual?" I said quickly and confused.

"It was in the brief packet the minister, my wife," He emphasized. "sent out to all the aurors for this mission yesterday. It regarded the magical object. Didn't you read it?"

"I do remember an envelope at my house yesterday, sir, but I was too busy-"

Burning another letter from-

"If you're serious about becoming an auror, girl, it is important to read the latest discoveries about the perpetrator." Mr. Weasley said to me harshly. He looked at Mr. Potter. "Harry, bringing her was a huge mistake! She could jeopardize our entire raid! If Bryne escapes again, Heromine and the entire ministry will be very upset. "

Mr. Potter frowned. "Celestia," He said.

"Yes, sir?" I said shuffling forward.

"I have an important job for you. I need you to guard the outskirts of the watchtower."

"Guard the border?" I repeated with shock. "With all due respect Mr. Potter, I'm training to be an auror. How am I suppose to gain experience if I'm not with you and Mr. Weasley? Besides, there's only two of you and who knows many dark wizards are up there with Bryne! You'll need all the help you can get!"

Right when I said that, about two more aurors appeared next to us. A middle age man with a black pepper hair and hazel eyes, dressed in black linked arms with a young women dressed similar like him. She has tanner skin than him with smooth blonde hair tied in a bun. They looked like husband and wife.

"Sorry we're late, Mr. Potter." The man said in his American accent. "We had to portkey to Ireland than apperate here. I'm Dave, by the way. Dave Richards, and this is my wife Eve. We're from MACUSA and ready to assist you."

"Hello," She said.

Mr. Potter and Mr. Weasley gave them handshakes.

"Great to see you again, Richards." Mr. Potter said as he stepped to the side to reveal me. "This is Celestia Smith. My apprentice of sorts. She'll be here assisting us as part of her auror training."

"Aren't you a little young to be an auror?" said Mrs. Richards.

"I recently turned seventeen and pasted my O.W.L's with flying colors. " I said to the condescending witch with a short glare, but then felt bad. Damn, my Hufflepuffness. "I'm sorry," I said shortly after. "I shouldn't have glared at you."

"And what about your N.E.W.T.S?"

I was about to answer, but Mr. Potter stopped us. "We have no time for details. I'm sure the two of you read your briefing packets?"

The Richards nodded.

"Good. Ron and I decided to split up into groups. The plan is to apperate then surrounded Bryne and his followers. Stun them. Disarm them. The ministry doesn't really care as long as we arrest them and stop them from performing the ritual."

"Then what are we waiting for, Christmas?" asked Mr. Richards. "Let's do this!"

"Yeah!" I said with enthusiasm.

"Celestia," drawled Mr. Potter.

I frowned. "I know. I know. I'll guard the entrance to the stair case as well as the field."

"Good. Ron, let's go."

I watched the adults disapperate as I took a short jog to the first stair case and waited patiently. I could hear the popping noises of Mr. Potter and the others appearing and the shouts of spells being spoken.

Why don't you go sneak a peak? said my consciousness.

"No, Mr. Potter told me to stay here." I said aloud. "He told me to guard this staircase in case someone or something comes."

I fought every instinct to not charge up there and help. A heartbeat passed then two which felt like five. All of a sudden, I heard Mr. Weasley shout,

"HARRY!"

Mr. Weasley's shout sounded concerned like if it was a matter of life or death . I whisked my head around and without a second thought I apperated to the top of the watchtower. It was mostly crumbled apart from the some scattered parts of the remains of a stone wall. I hid there and gripped my wand tightly. With a steady breath, I took a peak out of the unraveling scene.

Mr. Weasley was stunned into an unconsciousness state. The Richards were being held by two dark wizards. Their wands at their by the Richard's throat. And my mentor, Mr. Harry Potter was tied up in a tight rope. It was a Carpe Retractum charm, no doubt. The charm ties back the opponent and being pulled towards the caster. The caster that charmed Mr. Potter was none other than Liam Byrne. His back was towards me, so I couldn't get a good look at him.

"Harry Potter. The boy who lived. Master of Death. Head Auror for the Ministry of Magic." said Liam's voice that was deep. "What a lovely surprise to see you and your friends to show up here to a historic moment. Then again, I wasn't too surprised."

Oh, yeah, well I love to see the look on your face after this spell. I thought to myself as I was about to step out and shout a stupefying spell at him, but then he added. "Thank you, Mr. Smith for sharing this information to me."

I stopped moving as my heart dropped to the pit of my stomach when I saw my father step out of the shadows and into the moonlight beam. His blue eyes had dark circles underneath them giving him a hallowed appearance. He wore a nice vest and trousers over a black cloak that flapped against the sea breeze.

"You made an unbreakable vow to me, Byrne." My father said coldly. "I'm expecting you to keep it or my resources will disappear."

Liam Byrne 's head turned right when a moonbeam ray fell on him like a spotlight. He looked about nineteen, maybe twenty with fair skin and autumn brown air that shifted through the breeze like seaweed in water. His rich hazel eyes held a cold, uncaring stare to my father.

"I always keep my promises, Zechariah" He said with a quite rage. "as I expect you'll keep yours."

My father said nothing as he slightly turned his head to the back and jerked it forward. My stomach sank to another level of sickness, when I saw my former best friend came walking into the light.

"I kept the orb safe like you wanted, sir" said Ethan to Liam firmly as he held a medium size wooden chest in his hands. He carried himself in a mature manner than I last saw him. It made him look older. His light blonde hair trimmed neatly as his white shirt and Slytherin tie tucked neatly. Even when I look at him now, I can still picture his emerald eyes and smile full of warmth and laughter. But now it was dark and cunning, the looks of a true Slytherin.

"Excellent, Ethan. Now, put the orb on the stone table and align it with the key. It's nearly midnight." Liam said a tad bit harshly then stupefied Mr. Potter to an unconsciousness state.

If Voldemort in Liam's state twenty years ago would have taken this chance to killing Mr. Potter, but this is what separated Liam from Voldemort. He didn't care about eternal life, but being well known. The more popularity he gained; the more the ministry would realize that he is unstoppable.

I didn't even realize that there was a stone table nor an ancient doorway that stood by the cliff side of the watchtower. So much was happening at once, I didn't pay attention. I watched Ethan take out the orb with one hand. It was tiny compared the box. It was about half the size of palm smooth and black like volcanic obsidian. The stone table itself was just a circle slab of grey stone that had ancient runes carved at the rims.

I knew I should have stunned him or at least accio the thing to me, but some deep curiosity took over me. I wanted to see what happened next. Creeping a little closer as quietly as possible, I watched Ethan take the orb and heard it click upon the stone has he placed it in the slot. Liam then took out his wand and pointed it towards the sky. He shouted a spell and out of his wand came out grey sparks that dispelled the clouds, revealing the full moon's majestic serene glow.

Up on top of the arched doorway, there was a crystal shaped like a cut out diamond. With the moon's glow, it sparkled in rainbow hues. Moments passed and it shifted higher and higher in until it was at the center of the sky. Then as the moonlight beam passed through the crystal, a brighter beam of light shot, cutting through the air like a knife and onto the obsidian orb. Instantly, tiny balls of white light appeared inside like if a starry night was trapped inside. The runes around the stone table began to glow white as well as the ones on the archway. A short of thin veil that looked like ink in water began to appear through the doorway.

If this wasn't a ministry raid and a madman's opportunity of great power, I would enjoy the serine atmosphere a bit more and the beauty of the glowing runes on the stone table and archway.

"How beautiful," I quietly muttered in awestruck as I step backwards. A twig snapped underneath my boot. It snapped and cracked very loudly. Damn, my hufflepuffness.

Liam, Ethan, and my father whipped their heads towards me. I ducked as Ethan yelled, "Bomarda!"

I jumped out of the way before the spell reached the stone. It exploded on impact, sending crushed rocks and rumble everywhere like confetti.

"Stupefy!" Liam yelled.

I raised my arm and swirled it a clock like movement as I shouted, "Protego!"

The spell ricocheted off my invisible shield charm just in time, which caused a tiny dirt cloud.

"Celestia?" My father stared at me with wide eyes as he lowered his wand "Is-is that really you?"

My eyebrows furrowed angrily as my eyes glared at him with such hate. Then, my expression softened by how low he sunk now.

"Well, look who it is, gentlemen? Miss Smith, how nice of you to join us, welcome." Liam said with a slight bow then pointed his wand at me. "I heard so much about you from Ethan."

I shifted my gaze to Ethan who looked away from me with guilt then back to Bryne.

"You'll pay for this, Bryne! All of you will pay!" I shouted, gripping my wand and shifting my arm to each of them ready for a counterattack. "The minister will not allow you to continue these vial deeds."

"Celestia, stop." Father warned as he raised his wand. "Listen to me, I'm your father."

"You stopped being my father when mother died!"

With patience running extremely thin, he pointed his wand at me. "I said stop. Imper-"

But before he could finish the incantation, I quickly shouted with an upwards swish and downward flick, "Fumos Duo!" My wand sparked out hues of dark red, conjuring up thick red smoke clouds that was intended to blind all those in front of me, causing confusion. I couldn't allow my father or Ethan to get away from this terrible act. I remembered how far I was from the table, so I used this small diversion to get the orb as quickly as possible. Through the smoke, I passed Liam.

"GET HER!" He barked to his subordinates as he turned to probably immobilize me, but thankfully the smoke closed up before he could cast the spell.

When i reached the table, I stretched out my arm and felt the stone in my grasp. The power surging from it made it stick like glue. I grunted and lifted it up with all of my strength. "Got it," I finally said as I stumbled backwards a bit. A yellow spark missed my feet by a few inches. I held up my wand towards the direction where the spark came from. Through the mist, Ethan walked towards me.

"Celestia, give me the orb. I don't want to have to hurt you." He said firmly, wand pointed at me.

"Y-you already have. J-joining a man like Liam? That-that isn't like you, Ethan, you-you were my friend." I stuttered as I took a small step backwards, nearly touching the archway that was at the edge of the cliff.

"If you give me the orb, me and you will be the best of friends." He said with a handsome grin that oozed deception. "It would just be like old times. Isn't that what you want?"

I took a step towards the edge of the cliff. "Yes," I admitted with a shaky hand as I kept my wand fixed on him. "but not like this, Ethan. Liam has you under the imperious curse."

Ethan laughed. "Imperious curse? Celeste, dear, I joined with my own free will. You see, I've learned so much from Liam than Hogwarts could ever teach me. He can teach you too. We're one of the last few families who has pureblood descendants, you know. As a former Slytherin, it's my job to keep the pureblood lineage intact for the future. So, step away from the cliff side and give me the orb."

I did no such thing. I had to get the orb away from this place and back to the department of mysteries. They'd know what to do with it. I took a quick glance over my shoulder and stared at the sea below. My best chance was to go off this cliff, summoning a bubblehead charm. I couldn't disapperate, Liam put up an Anti-Disappartion Jinx possibly after Mr. Potter and the others attacked.

"Celeste." Ethan warned. "Don't."

I gave Ethan a hopeful look. "I'll save you, Ethan. I promise."

I stepped off through the ancient doorway and began to free-fall off the cliffside.

"Celestia! No!" He screamed jumping after me.

At the sound of his cries, the orb in my hand started to pulse then exploded, plunging me in a world of darkness surrounded by starlight.
