Disclaimer: I don't own Harry Potter, J.K. Rowling does. Praise Merlin for this wonderful universe she created. I only get to play around in it. I don't own Hades either, I kinda based him off of the Hercules movie.

Which I don't own either. I don't even own a car people.

The Dark Lord's mystery was harder to figure out than Regulus expected. But thankfully, after a few months of listening in whispered conversations and linking information together, he figured out the blackest of magic the Dark Lord had created. Regulus was no angel himself and understood the importance of learning both dark and light magic. However there is a line that even a Black won't cross, and that's certainly saying something considering the questionable sanity of some members of the family. After some research provided readily by the Black family library, Regulus discovered more than he wanted to know about horcruxes and some disturbing rituals. He found what he needed to know anyway. How to destroy a horcrux.

Regulus had everything ready to implement what most people would consider suicidal if the Dark Lord ever found out of his treachery. After placing his small note in the fake locket, no one would notice it was missing because of its sheer gaudiness, he closed his eyes and apparated silently to a seaside location where horcrux was residing. Regulus opened his eyes and smelt the frigid salty air. Quickly scanning the area for anyone who could have noticed his sudden appearance, he then calmly walked towards the foggy cave.

Twisting the fake locket in his robe's pocket, Regulus frowned as he remembered the near death experience of his elf Kreacher. The poor elf had been sobbing at Regulus' feet in gratitude after he had called for Kreacher when Regulus grew worried if Kreacher was doing fine in the Dark Lord's presence. Regulus knew the fear and awe the Dark Lord could inspire, but Regulus would've hated to learn his elf had been harmed because the Dark Lord was displeased. A disheveled and gasping house elf quickly indicated something along the lines of Regulus' thinking had occurred. It had taken some time for Regulus to pry out most of the story Kreacher had because the old elf was so traumatized. After doing so, figuring out the why took much patience and research. The where of the horcrux was easy when your own elf was almost sacrificed by the Dark Lord. His thoughts were interrupted by his approach to the mouth of the damp cave. Regulus noticed the small and likely unstable boat at the end of the old dock.

Walking tentatively towards the boat Regulus muttered to himself, "What am I? A Gryffindor? This might be proof I'm actually related to Sirius."

Kicking a pebble with unneeded force, he chuckled darkly, " I suppose my sense of morality hasn't been twisted as it should be after all I've been through..."

Glancing back, and sighing slightly, he quickly turned back towards the boat. Picking up his pace, he noticed movements in the water near the boat. Squinting a little and taking out his wand, he whispered, "Lumos"

Paling at the inferi reaching for him in their eternal unquenchable hunger, Regulus quickly turned off the bright light. Regulus waved his wand to put a few wards on the boat to protect himself in his short voyage. Taking a deep breath, he stepped in. The small boat slowly moved towards the small island in the body of water. After sitting down for a while Regulus called out, "Kreacher."

Popping into the boat the old elf bowed to Regulus, " Yes Master Regulus? Of what service can Kreacher be?"

Regulus smiled down at his house-elf, "Kreacher, I need your help in destroying the Dark Lord's horcrux. Leaving you to die here was wrong of him."

Kreacher's ears drooped down slightly after nervously glancing at the dark waters, "Master Regulus , I did as you-"

Regulus cut him off, "I know, but, I need your help. I won't be endangering your life more after this!"

Nodding in understanding Kreacher said, "How may Kreacher be of service?"

Regulus indicated to the island, which they were about to reach in a few moments, "When we get to the island, I'll tell you."

The boat hit the island and Regulus carefully stepped onto the rocky island with Kreacher at his heels. Regulus looked down at the rectangular container and heard Kreacher shakily mutter, "The salty, salty water. Kreacher could never stop."

Silver eyes steeling with resolve, he asked Kreacher, "The Dark Lord commanded you to drink the water in order to reach the bottom and place the horcrux?"

"Yes Master Regulus, it is the only way. Kreacher only escaped because Master Regulus called."

Nodding to himself, Regulus looked down at the container and reached for a full cup of the potion. Drinking the potion and almost gagging at it, he finished it and served himself another cup. Before drinking the second cup he ordered Kreacher, "You must take the horcrux, get out of here, and destroy it if I don't make it. Don't allow me to stop drinking from the container." Glancing down at Kreacher's wide eyes, he whispered, "Kreacher these are my orders. Don't listen to anything I say after this point."

"Yes Master Regulus, Kreacher understands."

The next few minutes felt like hours for Regulus, his throat felt like it had fiendfyre cast at it and the dark waters full of inferi never looked so inviting. After a few minutes, Regulus begun sliding down and weakly asked Kreacher, " Help me. Help me, give me water." The house-elf's only reply was a morose reply, "Kreacher is sorry Master Regulus." He pried the yellow cup from Regulus' grasp and filled the cup again to force his master to drink the potion. The scorching thirst was the only thing which occupied Regulus' mind. His mutterings and weak demands to ask Kreacher for water were meet with a faithful house-elf who kept refusing the wishes of his master. Kreacher's salty tears on Regulus' face were further torture as he kept drinking the potion. Eventually, Regulus heard the words he wanted to hear after what felt like ages, "Master Regulus, this is the last cup. Kreacher could give water after he destroys the horcrux like Master Regulus commanded-"

Regulus roughly muttered, "Yes, yes. Kreacher do as I said. Go now! The horcrux must be destroyed!"

Kreacher quickly bowed and retrieved the horcrux, popping away to try and destroy it.

Regulus saw the water at the edge of the island and desperately crawled towards it. Reaching the water and scooping up a shaking hand for water, he hardly noticed lifeless hands pawing at him and slowly pulling him into the water. When a quarter of his body was submerged in the water and the thirst felt somewhat alleviated, Regulus noticed the inferi already had a firm grasp on him. Eyes widening in horror, Regulus tried to get away but only brought more attention to himself. He felt a greater amount of hands, pulling, grasping, clawing. Load moans of hunger filled Regulus' ears when his body was finally forced underwater. Fighting in final desperate attempts to reach the surface he heard a distant cry of anguish before his burning lungs gave out and he felt his vision go dark.

Regulus moaned in pain, he felt like he was sat on by a fat dragon with a desperate weight problem. And the uncomfortable bed he was lying on was rock hard and poking his back. Placing a hand on his head to alleviate some pressure he slowly sat up and squinted his eyes in the darkness he was enveloped in. Hearing some creepy distant voices, he looked around and realized he was still in a cave but somehow laid near the bank of a river flowing deeper into the cave towards the quiet moaning voices. Eyes widening at recognizing the possible danger of the inferi, Regulus quickly tried to retrieve his wand. Only to find himself without one. Shaking slightly, Regulus dragged himself away from the bank and bumped into a cave wall only after dragging himself for two feet. Regulus groaned in frustration and placed his forehead against the damp wall.

An amused voice called out, "Hate to interrupt Reggie boy, but we're on a time crunch and a god of the underworld can only wait for so long."

Regulus quickly turned around despite the sharp pain he received, "Wha-"

Eerie blue flames surrounded an imposing dark figure on a long boat,"I do agree on our need for a house expansion, but since most of the human population won't stop breeding. It's any wonder work gets done here at all."

Regulus blinked in shock and whispered to himself, "I'm dead?"

The figure glanced down at their nails in boredom,"No shit, tough luck with how that Dark Lord defying plan kiddo."

Regulus shook his head, "There must be a mistake, I kne-"

"Look, I came here for a specific reason. Do you think I greet everyone at the beginning of their afterlife for no reason? No, I don't." The dark figure gestured to a seat on the boat, " Now get on the boat so we can talk on the way."

Nodding numbly, Regulus shakily walked towards the boat and settled onto the seat offered. The boat began to move itself deeper into with an eerie similarity to Voldemort's boat.

"The name's Hades, god of the underworld, yadda yadda. It isn't often that I have the possible opportunity to mess with the sisters of fate. But today's your lucky day kiddo!", wrapping an around Regulus' shoulders Hades gestured wildly, " Because you have the once in a lifetime opportunity to go back to your dimension in good health!"

Regulus hunched over a little in gloom , "Why would I want to go back? Even if my plan had worked, I would have ended up on the run from Voldemort for treachery."

"Ah, mi amigo, that is a real problem." Sitting up and stretching Hades drawled, "Well it's too bad you would join the Death Eaters again after getting another shot at life in a new body."

The gloomy teenage looked up in surprise, "Again? You mean I would be a different person?"

"Oui"

Regulus asked suspiciously, "Why?"

Smiling cruelly, Hades said,"Because I want Voldemort's horcruxes to be found and destroyed." Waving his hand as if swatting an insect away he continued, "The fates are always so strict and uptight about following the rules. I pride myself in knowing I throw rules of the game out and watch them try to work everything out according to plan in desperation."

Regulus gulped but didn't mention he didn't know there were multiple horcruxes. What in the world was Voldemort thinking!? Splitting his soul too many times could make him more of a creature of the night than man. He shuddered, wondering how many times the Dark Lord created horcruxes.

"So do you agree or not kid?" Hades asked impatiently.

Giving it some thought Regulus nodded, "I agree, on the condition that you allow me to be physically capable in my new body of doing these tasks and I must come from a pureblood family."

Grinning, the boat stopped moving and Hades opened up a seat behind him, which would just reveal a compartment under normal circumstances. In this boat, however, the seat revealed a blinding white light. "Agreed then," motioning towards the bright light he smirked and said, "You know, you have a bad habit of forgetting to remember the most obvious details. Perhaps next time you should actually tell your elf how to destroy the horcrux before sacrificing yourself."

Regulus looked down at the light in regret, then he felt a shove towards the bright light and heard a laughter in a cold voice, "You're of no use to me dead."

Piercing screams of a howling baby filled Regulus' ears and disrupted his peaceful slumber. Grumbling in his sleep and ready to return back to sleep, he shot open his eyes suddenly when he felt a smack on his bum. Screaming indignantly at being treated so callously, he heard relieved yells of joy on top of the screaming newborn.

"He's awake and kicking Molly! Don't you worry!" exclaimed a happy voice.

"I've never seen a baby come out asleep during delivery..." a professional voice seemed to mutter to their assistant.

The assistant replied, "I think it's a blessing considering the twin seems to believe it's being tortured." Then directed a question to the new mother of two more children, "Two healthy baby boys Mrs. Weasley. Do you have any names in mind?"

After settling down with the two newborns, Mrs. Weasley looked down at the fussy bright-red head indulgently, "This one looks like a Ron, doesn't he Arthur? Ronald Bilius Weasley."

Arthur chuckled, "Yes he does, what about this one? He seems trying to defy usual Weasley genes…"

After passing Ron to his father Molly lovingly traced the cheeks of his twin. Smiling down at the darker red head, with dark red curls similar to hers, "Alexander Septimus Weasley" glancing up to her husband, "Fitting name for the seventh son, isn't it?"

Bright blue eyes looked out in shock when Regulus, now dubbed Alexander, realized his new family are the biggest blood traitors of all traitors.

Alexander then proceeded to scream his lungs out in frustration.

A/N: Yeah so, this is the first story I've ever posted here. Hope you people like it. I was thinking about continuing the story with possible RegulusxHermione, but also was thinking about RegulusxLuna. I think both would be good pairings. So yeah .u.

Oh also, Septimus is the name of Ron's grandfather and it also means seventh son. And you guys know how magical the number seven is .u. Powerful name huh ;)
