Harry Potter & the Demon Blood

Don't own HP so shoot me if I say other wise.

A/N: A few people asked about why Harry was so immature last chapter. Well I thought it over while I wrote this chapter. The reason I chose that best went with it in my opinion is that it is caused by his demon blood. More aggressive and slightly more disrespectful kind of thing, besides he's been around Inuyasha and that guy shows little respect to anyone, though he will show hesitant disrespect towards Kagome for good reason. After all, even a demon must sleep and when it is the wife/mate that is made, there is no real escape. Sorry guys, but that is kind of true about our relationship with women. Wanna keep 'em happy if we want to sleep peacefully. I should know.

Chapter Eleven

At twelve he heard them coming down. With in seconds Fred, George, and Ginny walked into the common room.

"Hey Harry, I hope you don't mind us inviting Ginny." Said the twins.

"None at all. Well Ginny, I'm guessing that the twins informed you of our meeting and why it is being done, other wise you would have hexed them for telling you about this but not why."

"Yeah it's for pranking right?" Ginny said.

"Yes, well let's get going now." Harry said as he stood and walked out of the common room with them following.

"Where to chap?" George asked.

"To the lair of four gods, where mortals tremble, bullies fear, teachers squirm at the possible wrath of humiliating ambushes and cause even the bravest student to run in fear. The four deities, Humiliation, Ambush, Confusion, and Panic. Within their lair unbelievable devises and spells of torture lay." He stopped before a carving of a full moon with a ring of the lunar cycle around it. He put his hand on the full moon. "Let's welcome chaos." He said in a frightening tone. The moons rotated and slid back into the wall before the wall slid up and out of the way. There was a tunnel that led into darkness with white mist that seemed to glow with out making light flowed along the ground. Harry stepped forward and the others followed, but with caution.

After a few feet the came out of the tunnel into a large black room with the fog fading into the shadows.

"Harry where are we?" Ginny asked.

"In the lair of chaos." He stepped to the side of the entrance and reached out for something. "Welcome…to the HQ of THE Marauders." Suddenly lights came on, nearly blinding them.

Ginny heard two gasps and then two smacks from where her brothers were while she still could not see. She looked towards them as her eyes finally started to adjust.

She saw them on the ground in a bowing position. She looked up at what they were bowing to. There in front of them was a large cavern of a room that was the size of a quidditch field and was separated into four areas by the path they were on and an intersecting one at the middle. The paths were about twenty feet wide.

At the cross road there was a fountain with a statue of a reddish stag with a grey wolf on one side, a large black dog on the other and a grey rat on its antlers in the middle of the water as jets of it shot up around them in arcs and other patterns. The basin for the water was five feet wide from the center. The area to her right looked like it was for fun things, like hanging out and reading, as it had several couches and chairs, a dueling arena and even several muggle items. The area to her left looked more like a living area, with beds, a kitchen sub-area and a closed of area that looked like it was a bath room, a rather large bath room at that. The area on the other side of the field to her left was, by the looks of it, a chemistry, potions, and invention workshop. And the last area seemed to be a library.

"Fred, George, get up before you get stuck like that." Harry said.

"How did you find this heaven, chap?" Fred asked.

"I am the heir of the Marauders and I got all of the notes. This is their HQ and the only other person that knows about this place that is still alive is Mooney and Wormtail so we can use it now. As you can see, this was also meant as a safe house when a prank went too wrong and they needed to lay low for like a month or ten. The best part is that my godfather took Wormtail off the list of who can have access and added me when he was here in my third year. So the only person we need to worry about is Remus, as he is the one who gave me the notes and stuff. Now then, I want to know if I can trust you three with something that I don't want anyone that I myself don't tell knowing. Even the old man."

"As long as it's not you joining the dark lord then fine, after all it can be too bad." Ginny said. Harry smiled.

"No, in fact, this is going to be something I use against Tom. Now then, Fred, George, Ginny, here is what I am wanting to tell you three. I am a half lunar demon."

"Wh-what?" All three Weasleys stammer.

"You heard me just fine." He dropped his ring's charm and showed them. He put it back up shortly after.

"So if you're a half demon, let me guess your girlfriend's a demon?" Fred joked, trying to get some humor out to get over his shock.

"Nope, half blood demon. You have all met her too."

"Who and for that matter, when and where?" Ginny asks, while her brothers try and pick up their jaws.

"Diagon Alley when you went there."

"Then why don't we remember seeing you?" Ginny asked again.

"Simple, we left a trap for the rest of your family and the others, and you just got stuck in it. Here look at this photo. It'll give you your memories of that time erased back." He hands them a blank photo. "You'll see the image when you remember." He explained.

They all looked at the photo and suddenly a symbol in crimson appeared and flashed. And then the memories of that day came back to them.

The twins broke out laughing, at how Harry had acted, the prank played, and the fact that no one knew.

"Ingenious Harry! Purely Ingenious!" They said. Ginny soon joined them in their laughter as well.

"Harry," Ginny started after she calmed down a little. Seeing that she had his attention she continued. "What kind of spell was that?"

"Blood magic. It is something a few demons can do. Half demons and blood demons do it the best. Oh yeah there is something else that I want to tell you. Well more like have you do." He takes a book out of his backpack that they just now noticed. He opened the book. "Since you will be joining Marauding Syndicate, as that was what this really was about, we will have to figure out what your animegus forms will be." He pulled out his wand. "Innellus Beastailion."

With that a wave of multi colored light shot out and struck them. Ginny turned into a fiery three tailed genet with a molten mix of red, yellow, and orange with normal black markings, spots, and tail stripes, which was an odd coat for the one tailed genet. The twins turned into twin bobcats with light reddish tan coats. They looked at themselves in a mirror that Harry conjured. The twins gave big grins while Ginny stared in awe as her tails swished happily. Five minutes later the spell ended and they were back in their human forms.

"That was unbelievable Harry." Ginny said still in awe at her animegus form. The twins just kept grinning.

"So what should our nicknames be?" Fred asked.

"My twin has a point. If we are to be of the Marauders then we must have nicknames that pertain to our animegus forms." George added.

"But Harry doesn't have one yet." Ginny interrupted.

"Yes I do." Harry said. He turned into a midnight black wolf. There was a small flash from his right forepaw as he deactivated his ring. All of his markings from his demon form transferred onto the wolf form. His tail extended and plates formed on it. The twins noticed two thin bars that looked to be three inches tall, half an inch thick, and four feet long on his back. They looked like they were glowing slightly and made of moon light and the end near his rear had curves on the lower half. When they asked about it the bars went up and to the side a little so that they were at a forty five degree angle from their first position. Spheres made of the same glowing substance appeared and three bars that each were half as wide as the main one swung out, all of them not actually touching the sphere which soon gained a hook like bar on it. The three that came out extended and gained angles and triangular sheets of the light formed between each of the four beams on each wing. He changed back, leaving his charm off.

"I already have a name for myself, as Mya, my girlfriend, already chose it. My Marauder name is Howlbeam. And I think I will let you guys chose yours. So what will yours be?"

The twins looked at each other before looking at Harry again. "Messers Smiles and Spots at your serves, Mister Howlbeam." They said with a bow.

Ginny thought for a moment and then spoke. "Mistress Tryfire at Mister Howlbeam's servers." She paused for a moment. "Mistress Tryfire suggests that she goes by Mister instead of Mistress for now." The twins clapped and agreed. Harry nodded.

"Messers Smiles and Spots would like to inquire Mister Howlbeam of whether Mister Howlbeam's girlfriend will also be among our number of the Marauding Syndicate?" The twins asked.

"Mistress, but for now Mister after the request from Mister Tryfire, Foxfeather has already been of the Marauding Syndicate since it's founding. Mister Foxfeather is a crimson seven tailed fox with gold tipped tails and ears and phoenix like wings. Also Mister Foxfeather will be joining us on the second Saturday of this month for an unknown length of time." Harry paused and looked at a clock. "Ok now that it has been five minutes after your initiation we can talk normally again. Also, the Mister part is to only be used in messages like what I did in the great hall."

"THAT WAS YOU?" The three new Marauders yelled.

"Yeah. Anyways, unless we are doing a message but are talking to each other in HQ we drop the Mister bit. So right now we only go by Smiles, Spots, Tryfire, Foxfeather, and Howlbeam. And if anyone else joins they will have to go through the same thing you three had to, including all Marauders present are stuck talking like they write for five minutes. Good joke that Sirius added. Now then let's get acquainted with HQ. First thing first though. New marauding marauders in the Marauders' Lair." He clapped his hands as he said that with a flash of crimson light and then the statue glowed crimson.

The water stopped for a moment. The statue in the middle rose up with a basin of four feet wide into the air. There was a flash from where it used to be and in its place appeared a large black wolf with markings and wings like the ones on Harry's animegus form standing in the center. On one side of it stood a crimson fox with seven tails and phoenix wings with golden tips on the tails, ears and feathers. On the other side there was another seven tailed fox, this time with snow white fur and red tipped ears and tails. In front of them sat two bobcats with light reddish tan fur, grinning widely. They all were on a raised platform in the middle of a basin that was twice as wide as the original. The edges of the platform in the middle had 'M's with interweaving 'S's engraved into it. The basin of the original four Marauders had 'M's engraved into the side, with the 'V' of the M being a place were water would spill out from into the lower basin. As the water fell once more from the upper basin it did intricate spirals. The jets of water that used to shoot up from the edges of the main basin were now shapes made of water launched to where another area from spheres along the edges. Diamonds, spheres, squares, eggs, and other shapes would shoot from sphere to sphere in a bouncing like way while jets of water shot from wands and potion bottles in between the spheres and 'M's on both statues.

Letters made of water shot up and hung there for a moment, allowing them to be read before continuing their course to a sphere. 'Welcome, new members, to our lair. What a joyous time it is for the Marauders to be joined by five young corrupted- we mean inspired people. Enjoy this show.'

With that the lights dimmed and lights came on with in the fountain. Glowing colored balls of water shot up colliding with each other and appearing to look like fireworks. From behind the 'M's that engraved the side of the main basin came the iridescent mist, this time changing color and producing real light. The mist took forms of animals and began to play in the field created by it all while the 'fireworks' continued over the statues. In the finally each of the spheres shot up large balls of multi colored water over the upper basin. They all collided at once, creating a huge 'firework display' that changed color as it spread and fell. With that the water show stopped, continuing with its usual display as the mist receded.

The twins whistled loudly while Ginny stared in awe. Harry started clapping, and soon the other three joined in. to the three's shock the statues all bowed to the applause. Though the bobcats followed up by mooning them in a head stand. This caused the twins to laugh.

"You know,"

"We really,"

"Would,"

"Do something,"

"Like that."

Ginny looked ready to hit them while she laughed. Harry shook his head sadly while laughing as well.

They stayed up till four in the morning exploring the lair before finally heading up. As they approached the Fat Lady she looked at them, spotted Harry and opened up with an 'Eep'.

"Howlbeam what was that about?" Fred asked as they sat down in front of the fire.

"Yeah we didn't even give her the password." George continued.

"Yeah well after my talk with the old man I came here and couldn't get in cuz I didn't know the password and so after several nice tries I snapped and threatened to make the damage that Padfoot did in my third year look like a paper cut." Harry said with a little grin.

The twins whistled.

"Well night you three. This vixen needs to go to sleep." Ginny said as she headed up to bed.

"Smiles, I think it is official now that she is a vixen." George said.

"Yes, before it was just a figurative saying, but now, my brother Spots, our little sister is quite literally a vixen." Fred said, wiping away fake tears.

"The sun hath long retired. I shall leave you prowling felines to retire to my chambers. I bid you adieu, my friends, my allies." Harry said with the voice that he used when he joked with Mya.

"We bid you adieu additionally, esteemed heir of the Marauders and founder of the Marauding Syndicate, Howlbeam." They replied.
