A/N: Sorry its been so long since I last updated, but there have been some personal problems and computer problems that I had to deal with. I hope that you all understand and that you enjoy the new chapter.

Thanks to Chelanzar, Kkenny, Cdkobasiuk, MerlinDCSA, ApocSM, HPFan87, Admiral Kenny, and Amros for their reviews.

Pleione: Glad that you liked the threesome, and glad that it did surprise you. As for your question yes I did get the idea from the Slider episode, and at first I wasn't going to use it, but then I found that it fit my story and that I needed it, so I used it.

Benwa: Yeah your right the chapter could have used some more action but it was suppose to be a more laid back world because I know there would be a lot of action in this chapter to make up for that one.

ContemporaryManner: The Tonks with Harry is the sixteen year old and she is from War World (Chapter 12). The older version of Tonks is the one that is still on Harry's home world. No I have never read the Pendragon series, the concept behind this story comes partly from the show Sliders. Tempus shows the date that it would be on Harry's home world, and Accro Tempus shows the real world's date. You are right it does get a bit confusing, just like your stories can at times. I suppose having the two Harry duels was a bit far fetched, but I felt that the chapter would be more interesting with the duel in it and thats why it is there. Don't up yourself down I really like your stories and can't wait to read more of them. For those that haven't read ContemporaryManner's stories shame on you because they are excellent.

Shadow's Survivor: No offense taken and it is your right to feel that way. I will be the first to admit that the dialog between the characters is lacking. I have never said that I was great at writing dialog, and I am sure that is just one of many areas that I have to work on. Thanks for your view of it, and I will try to improve their personalities.

Silverkitcat: There are similarities between this story and Sliders and the reason that it isn't a crossover is because I am not using the Slider characters. As for when Harry will get home, well that will be a matter of chapters, because there are worlds that I stilll want him to explore before sending him home.

Harrysfriends: Yes I am a fan of Sliders as well as Harry Potter and that was the inspiration for doing this story.

Recap

Right before the time for Harry and Tonks to leave the world, Harry went to see Remus. He gave Remus a sack with five hundred galleons in it to help pay off the Harry of this world's debt. He then went to meet Tonks in the supply room, which should be the Room of Requirements. Harry used an unlocking charm to unlock the door and followed Tonks into the room. Tonks and him made sure they had all they bought on the world and waited for the timer to hit zero. Then when it did Harry opened the vortex and he followed Tonks through to find out what the next world would be.

Chapter Thirty: Demon World

The vortex opened on to the new world and Tonks came out with a light thump as she landed on her feet. Harry came out a moment later, and also landed on his feet surprisingly.

Harry sets down the bags he is holding and looks at Tonks. He thinks for a moment and makes a light source appears above them and a comfy couch to appears in front of them.

"Well we are at least in a normal room of requirements." Harry said as he looks at the timer. "Well if this isn't my home world then we are stuck here for one day, five hours, and thirty-eight minutes, so we might as well get comfortable."

Harry sits down on the couch and motions for Tonks to sit down beside him. Tonks looks at him for a moment and then sits down beside him.

"Shouldn't we check out this world and see if it is your home world or not?" Tonks asked as she moves her arm and places it on Harry's shoulder.

Harry looks at her for a moment and then smiles broadly. "We will check it out shortly, but first I just want to take a minute alone with you. With each world we go to there is no doubt some sort of problem that we have to deal with, and even if this is my world it wont be any different."

Tonks looks at Harry with a look of shock and confusion on her face. "I know your world still has the Voldemort problem, but we will deal with it like we have all the other challenges before us."

Harry looks down as he thinks about his world. "It is more than that to me. When I get back to my world, if I get back, then I will once again have to face the fame that comes along with being the Boy-Who-Lived. On top of that now I will have to deal with all the fame that might come from venturing to new worlds."

Tonks smiles as she leans over and kisses Harry. "We will deal with it together Harry, like we have dealt with the other challenges before us."

Harry holds Tonks close to him and inhales her scent deeply. "I know we will, I am just concerned that if we are on my world then, we will have to deal with you having a double here."

Tonks pulls away from Harry and looks at him. "What? Harry we have dealt with doubles on other worlds and we have seen them look like a lot of things. What do I care if I have a double here that is older than me? That isn't going to change anything between us, unless you allow it to change us."

Harry pulls Tonks close to him again and holds her tightly. "You're right, I am being foolish. I know that nothing will change the love that I have for you, because you're the first woman that I have truly loved."

Before Tonks can say anything in response to what Harry had said the Room of Requirements starts to change around them.

"Harry what's happening?"

Harry stands up and looks at Tonks. "Someone must be wanting to use the Room of Requirements. Quick we better hide and see what is happening."

Harry makes the couch disappear and then takes Tonks over to a corner of the room and pulls his wand out. He mutters an invisibility charm that will conceal them from whoever is coming into the room. He then mutters a silencing charm around him and Tonks so he can talk to her without being heard and blowing their concealment.

The room changed in to that of a meeting room with a large table and chairs in the center of a brightly lit room. Harry and Tonks watch as Hermione, Ron, and Neville walk in and take a seat at the table.

"I wish Harry was here, he would know what to do." Neville says as he takes his seat.

"We all wish that Harry and Dumbledore was here Neville because it would make this a lot easier, but they are missing and we have to be ready to help where we can." Hermione says as she looks at Neville with understanding eyes.

"How are we suppose to help against those bloody demons?" Ron says as he looks hopelessly at the table.

"We all have to do are part Ron, even if it does seem like a lost cause." Hermione says as she makes some books appear on the table in front of her. "I have been doing some research into these demons and it is clear to me that our magic alone will not be enough to defeat them."

"We bloody knew that already Hermione, mind telling us how we can defeat them? We have lost a lot of good people already!" Ron says as he looks at the books in front of Hermione.

Harry looks at Tonks for a moment as he wonders what is happening. Is this his world, and has Dumbledore gone missing along with him?

Tonks has a look of concern in her eyes as she moves closer to Harry. "We have to try and help them. Especially if this is your world."

Harry looks over at his three friends. "I am not so sure this is my world Tonks, when I left I didn't hear anything about demons though that could have happened in the time I been gone."

"Even if this isn't your home world Harry we can't just sit back and do nothing." Tonks says as she looks over at the trio sitting at the table.

Harry looks down at the floor for a moment and then back at his friends. "I know we have to, but we must first find out more about this world."

As the trio sat at the table and Harry and Tonks watched them a loud siren echoes through the room, like that of an air raid siren.

"Bloody hell!" Ron yells as he stands up from the table.

"This is the third demon attack so far today!" Neville says as he stands up.

Hermione gets to her feet and looks at her friends. "We better get to the Great Hall and see what is happening. They will be doing a head count to make sure no one else was taken by the demons."

Harry watches as the trio leaves the room and it reverts back to its normal darkness. Harry thinks of lighting so that he can see and then looks at Tonks. "I think it is best that we go to the great hall and see what is happening."

Tonks looks a bit concerned as she looks at Harry. "We can't just walk in there, especially with your double being missing."

"I know we will have to stay concealed until we know exactly what is happening and then we will find someone and reveal who we are. It will be more difficult without Dumbledore being here, but I am sure that we can figure something out Tonks."

Harry carefully keeps the invisibility charm and the silencing charm on him and Tonks as they make their way from the Room of Requirements and begin their journey towards the Great Hall.

When they enter the Great Hall they find that it is full of witches and wizards. It seems that Hogwarts has once again become the refuge for all those seeking shelter from the latest attacks. Harry saw that Alastor Moody, Kingsley Shacklebolt, Filius Flitwick, Rubeus Hagrid, Severus Snape, and others that he didn't recognize right off. Then he looks over from that group and sees Arthur, Charlie, Bill, Percy, Fred, and George Weasley standing off to the side.

Harry stops and whispers to Tonks even though he has the silencing charm in place. "We best be careful Mad Eye can see invisible people, and if he spots us we could be in trouble since we don't want our cover blown right off."

Harry and Tonks make their way back towards the rear of the Great Hall hoping to be far enough way that Alastor wont see their with his magic eye, as they try and find out what is happening.

Arthur Weasley makes his way over to where Alastor is standing. "Alastor how bad is it this time?"

"I have been informed that three groups of demons have attacked Hogsmeade. They have finished what the first wave started and it appears that they will be heading this way."

Kingsley looks at Alastor for a moment and then speaks. "Do you know how many is in each group?"

Alastor looks at Kingsley. "We don't have an exact number but we do know that there is at least twenty demons that attacked Hogsmeade, but there may have been more that weren't involved in the attack."

"How are we going to defend against that many demons at once?" Arthur asks as he listens to what is being said.

"We are hoping that they will not be able to get into the grounds, but so far all attacks by the Aurors has been in vain because a lot of these demons are resistant to our magic." Alastor says as he looks gloomily at the floor.

Harry leans towards Tonks. "This is not going to be a battle that they can win with magic."

Tonks looks at Harry glumly and then gets a look of hope on her face. "Harry what about the weapons we bought on the last world?"

Harry thinks about it for a moment and then remembers what Dean had said about the daggers that Tonks had purchased. "That might just work Tonks, those daggers you bought are suppose to be magically enhanced for fighting demons. Lets head back to the Room of Requirements and check out those daggers in private."

Harry and Tonks carefully make their way back over to the doors of the great hall and get lucky that an Auror was coming in as they went to leave. They easily slip out unnoticed and make their way towards the Room of Requirements.

"Harry how do you plan on finding out what the enhancement is, since we don't know how to find it?" Tonks asks as she pulls one of her daggers out of the bag as they come into the Room of Requirements.

Harry looks at her as he makes a table appear in the center of the room. "I was kind of hoping that the room would be able to help me with that problem. Since the room is able to make anything that the user needs, I was hoping that I could have it show me a spell to find out what enhancements were on the dagger to make it effective against demons."

"That's only if it is truly special, and the Dean of the last world wasn't just saying that to sell the dagger." Tonks says as she places the dagger down on the table.

"Yeah that is also a possibility. I am hoping that he wasn't lying because if he was then we wont be able to help these people." Harry says as he thinks about what he needs and prays to Merlin that the room can help him.

Within a few seconds the room responds by placing a book on to the table that Harry had created. Harry grabs the book and looks at it for a moment.

"What is it?" Tonks asks as she looks at Harry and the book.

"It is a book from an era long thought lost. It is a book from the time of the old, a time of mages." Harry says as he looks at the books cover.

"Mages? I thought the last of the mages left the world." Tonks says as she looks at Harry in disbelief.

Harry makes two chairs appear and sits down at the table as he opens the book. "I don't know about that, but I know what this book says, and from what I can tell it is from the time of the mages."

Tonks sits down and looks at Harry. "So is that book going to be able to tell us how to find the enhancement placed on this dagger?"

Harry looks at the book and then back at Tonks. "Not exactly, but it will help us in the fight with the demons."

"How?"

"This book has ancient runes in it that will enhance the weapons from what I can tell. The problem is that I am not good at runes, and I only know one person that is."

"Please tell me that person isn't Dumbledore since we don't know where he is." Tonks says as she looks hopelessly at Harry.

"Actually he would have been my first choice, but thankfully he isn't the only choice. It so happens that Hermione is also pretty good with ancient runes, or at least I hope that the Hermione of this world is." Harry says as he stands up from the table.

Tonks stands up and looks at Harry. "How exactly are we suppose to get Hermione to help us with the runes when she is currently in the Great Hall?"

Harry pulls a coin out of his pocket that looks a lot like a Gallon. "I am hoping that this world also has the DA."

"DA?"

"In my fifth year we weren't allowed to learn defense against the dart arts. At least we weren't permitted to practice any actual spells."

"Why?"

"Because we had a really mean witch that was out to help old moldy I think. Anyway the students didn't agree with her decree, so we formed the DA, Dumbledore's Army as it came known later. That way we could practice using spells without her knowledge, and Hermione made these coins so I could alert members of the DA when there was a meeting being held."

Harry holds the coin in his hand and looks at it for a moment. "If this world has the DA then I should be able to send a message to her and have her come to me. Though that is only if she made these coins on this world as well."

"What happens if they don't have the coins? Even worse what if they do?"

"Well if they don't have them then I will have to get her here some other way. If they do have them how can that be worse?"

"Well as you heard the Harry Potter of this world is missing, so if you send her a message she may decide that you are a spy and bring down the whole Auror group on us."

"Shit!" Harry slams his fist down on the table. "I hadn't even thought about that. You're right of course and that means we will have to get her here some other way."

"We could try to make the runes ourselves." Tonks says as she looks at the book in front of Harry.

Harry picks up the book and begins looking over it. "There may be one way, but I am not sure that this will even work as I have planned."

"Anything is better than nothing is it not?"

"Yes of course but if I am wrong about this then all could be lost."

Tonks stands up and makes her way over to Harry and places her hand on his shoulder. "Harry whatever it is that your planning we will face it together. I have said this before and I will say it again. We are in this together, for better or for worse you are stuck with me."

Harry stands up and pulls Tonks close to him. "Listen to me Dora I love you and that means that I am willing to do whatever it takes to protect you. However this is very dangerous and for me to allow you to do this would be going against all that I believe."

Tonks pushes Harry away and stares at him. "You listen to me Mr. Potter you may be the first man I have truly ever loved, but I will not have you protecting me like a father would a child. I am more than capable of protecting myself, and I will do whatever you do, and if you try to stop me then I will not tolerate it."

"Tonks I know that you can protect yourself and I have told you before that I am honored to have you watching my back."

"Then what is the plan?"

Harry sits back down and opens the book to the page that he had quickly skimmed over. "There is a spell here that will open a portal to the time of old. According to this we will be able to go back to when Mages still walked the earth."

Tonks looks a bit shocked at this statement. "Your saying that it will open a portal to a time before the Dragon War happened?"

"From what I can tell that is exactly what this means, but I do not even know if the spell will work."

Tonks still looks concerned as she sits down. "If the spell words Harry then what?"

"Then I assume that we will go back to the time of the mages and I will try my best…" Harry looks at the expression on Tonks face and decides to rephrase his statement. "I mean we will do our best to get a mage to help us enchant weapons so that we will be able to fight these demons."

"What about the timer and us leaving this world?"

"Well if my understanding is correct about this spell. We should only be gone for six hours, but I may be wrong about that."

"So the spell will open a portal back to here, when the spell comes to an end?"

"That's the theory at least, but Tonks if you don't want to do this…"

"I never said I didn't want to do it, all I am trying to figure out is whether or not we will be stuck here forever or not."

"No, if the spell works as I believe it will then we will be back and able to get off this world, that is if it isn't actually my world. There is still that chance and that is why I feel that we really need to try and help where we can."

"Then we better hurry because I am not sure if the people of this world will be able to last six hours while we are gone."

Harry stands up with the book in hand and thinks about the things that he needs because there had to be a doorway drawn out to act as the focal point for the spell. Harry then begins to read from the book making sure to say the incantation exactly as it is written, so the spell will work correctly.

When he finishes the incantation the doorway begins to glow and then opens revealing the portal that is suppose to take them back in time.

Harry looks at Tonks and grins as he sees that the spell worked. He quickly picks up the sword that he bought, and then hands Tonks her daggers. "Time to go!"

Tonks takes a hold of her daggers and then holds on to Harry's hand as they walk through the doorway and vanish from the Room of Requirements.
