"Merlin," He started. "You are leaving heaven."

"What!? Now?"

"No tomorrow." He corrected

"Tomorrow?! Why?! I have never even left this house; very less heaven!

30,000 years ago heaven and hell were at war; that was until both of the kingdoms came onto an agreement.

Hell would still be hell and heaven would still be heaven and neither of them would get in the way of the other. No devils were to enter heaven as no angles were to enter hell and if anyone were to break this rule they would be sentenced to the disappearance from their existence, for they were not human and only a human souls can die and later be judge but for angels and devils it was very different; they either lived or disappeared as if they never existed different from humans that in which in the worst of cases would die and burn in hell.

That was until Uther, prince of hell arranged to marry Ygraine a human soul living in heaven pure as an angel and from that day on peace between the kingdoms was granted and full access for the kingdoms was granted to everyone after the birth of their son Arthur.

Wanting to keep things as they were no children or person below the age of 25 were allowed to attend the other kingdoms schools as they were to learn how to be angles or devils in their own kingdom; for if an angel or devil below that age was to pass to either kingdom an angel would be corrupted and die in madness and as for a demon it would get purified.

This was but a price they would have to pay and an inevitable one.

"Gaius," She looked at him with desperate and widened eyes. "promise me you will protect him no matter what, and take good care of him; please." She pleaded.

Gaius gave her a reassuring nod. "I promise." Hunit took a hold of the doors knob to leave when Gaius called for her. "And Hunit," She looked back. "be careful." Hunit retrieved her hand from the door knob and ran to hug her brother for what it seemed to be the last time. "You too." She said as she pulled back to look at his eyes and gave him a kiss on the cheek.

She walked towards the crib and took the baby one last time in her rams and kissed his forehead as she whispered: "Good bye, Merlin." And a tear fell down her cheek as she placed the child back to its bed. Her precious Merlin big bright blue eyes, pale skin 2 tiny white devil horns picking out of his jet back hair and 2 small black feathered wings sticking out of his back.

Hunit stormed out of the place and after that Gaius never saw her again.

Gaius had done everything in his power by the time Merlin was 14. He really had, he pitied the lad but he never let it be shown. He was not to go outside thus others could get alarmed, angels or not that was just a title; everyone at least has one speck of darkness in their hearts.

Merlin spent most of his time in the library, a big spare room that Gaius had used to keep some medicine books at the start of things. But, after Merlin had showed interest in them it had turned into a library with countless books about everything imaginable. The boy had`t a taste in particular in books he just liked to read and gather all that knowledge they presented to him. By the time he was 15 he could no longer keep the books Gaius bought for him. From then on Gaius just brought him lend books from the Cities library; he rent some every Saturday and returned those already read.

I Gaius calculations were right by the age of 20 Merlin's devil side would consume him; either that or his angel one would consume the other. At first he didn`t worried much about it but after he saw his calculations to be wrong he did have something to worry about.

"Your majesty." Gaius bowed to the Queen. "Oh, Gaius. Please don`t call me that we are friends. There are no needs for any kind of formalities." Gwen said as she seated to eat.

"We need to talk." Gaius tone was of worry and concern a rare tone for Gaius to have which earned him Gwen`s full attention. "Yes, please do tell me the reason as for why you sound like you are about to break up with me."

"It`s Merlin." As soon as the name 'Merlin' fell from Gaius lips Gwen`s preoccupied features appeared as she stared at Gaius. "Is he alright.?"

"For now."

"What do you mean?" Gwen studied Gaius eyes with great concern.

"Gwen, Merlin`s powers as an angel grow and grow with each passing day. Tough his demon side has to be yet mastered. They crave to be used Gwen." He said her name firmly. "When he gets mad things shake, when he screams things break and when he cries his horns turn black."

"But, I don`t understand I-I tough." Gwen was taken aback. "Yes, yes I know; things are`t supposed to be like that. If his wings are black his horns are white and if his wings are white his horns are to be black, that way both things are balanced and none gets out of control, but if he only knows how to use one of his sides; how can he master the other one?" He needs to learn how to so neither of them turn out to be his down fall. I his dark side takes over him here in heaven he will surely die."

"What do we have to do?" She asked with grave concern.

Gwen was in no way related to Merlin by blood but she cared dearly for him like a mother would. She was the only other living thing he had seen other than Gaius.

"Merlin needs to master his dark side."

"How will he do that? There are no books here in heaven that can teach him."

"You surely already know the answer to that, Gwen"

"But-"

"Gwen," Gaius said soothingly. "you know very well of Merlin's powers. I can assure you;, no harm can come to him. Even if something could happen. I was able to create a potion that will exchange his wings for those of a devil and his horns black. "

"But, Gaius," She began to protest. "Please Gwen. It is for the best." Gwen gave a sigh of defeat. "When does he leave?"

"As soon as possible."

"Tomorrow then, the passage to hell will be open for him by morning." Gaius gave her a thankful smile. "Thank you."

"Merlin." Gaius called as he entered the house. He went up stairs and checked Merlin's room and frowned when he did not find him there. "Seriously, were is that boy?"

"Merlin?" He called again heading towards the library. "I`m in here." A voice said back to him. Gaius entered the room and saw piles of books gathered around one table, books splattered across the floor in other words Merlin`s usual mess of books. From where he was standing Gaius could`t see him that was until-

Foo-sh!

His black wings opened as a: "Ha ha! I knew that would happen!" Left his mouth as he read the book with an exited expression his wings making brute movements, bringing some books down to the floor that stood behind him and then: "Gaius you are not going to believe this! Grace finally found out that Marena is actually a boy, and it was so cliche-"

Most of the time he could`t understand half of what the lad said. "Merlin." Gaius cut him of. "Yes..?" Merlin trailed of quite distracted by the book in-front of him."Gaius..." He ended a while later. "Merlin, this is important." Gaius stated firmly giving him a stern look. Merlin finally out the book down to look at Gaius, head quite raced so the mountain of books would`t block Gaius face.

"Merlin," He started with a sigh. "you are going to leave heaven." Merlin laughed. "Stop that Gaius it isn't funny." Merlin's smile gone when Gaius looked at him seriously. "You are serious?!" Gaius nodded. "What? Now?!" He shouted stressed. "No, tomorrow." He corrected. "Oh, yeah because that makes it so much better!" Merlin spat sarcastically. "Why? I have never even left this house very less heaven! I have been hiding all my life without anyone ever telling me exactly why, you and Gwen are the only people I know! I only know there is more because of books, books Gaius! No matter what you say this is never going to pass as normal and now you are just casually telling me to leave heaven?!"

"Merlin I don`t expect for you to be fine with it-" Gaius tried. "No you would be mad if you had." Merlin retorted. Gaius continued ignoring the fact that Merlin had opened his mouth at all. "but it is for the best." He explained. "Yeah so was hiding me." He sated sarcastically.

"Merlin, it isn`t hiding is protecting."

"Since when is hiding me form others is protecting? You only hide me because you are afraid of peoples reactions towards what I am!" He shouted.

"Merlin." He said fondly. "I keep you here because I made a promise to your mother." Merlin tensed at the mention of her Gaius barely talked about his parents or of what happened to them if he even knew. "Merlin, if people learn about the full extent of your powers they will want you dead as soon as possible out of fear of what you can do and achieve with them." Merlin didm`t want to say he understood but he did. He himself had been shocked with what they could do but only after he learned that little what things he could do with a snap of his fingers were not normally achieved so easily. Even so he asked: "What can I do?"

They may or may have not had this conversation before but he hoped that unlike last times Gaius would`t hold anything back after all he was the one dealing with it he could not exactly protect himself from something he did not know. "You are a creature of both angelic and demon like powers. If you were to want to do it no-one could stop you from ruling both heaven and hell after all you are the only one that would not be affected by it. You can live in both places without dying..." Now that part right there dying hues that part he had not heard before but it just made everything else not make sense. "Then why leave? If I stay here no-one will know of my existence and no-one will get hurt."

Gaius looked like he preferred to stay shut but knew better of it. "Because your demon side if taking over you and you know it . If you don`t learn how to master it you will perish and so will any chance of heaven and hell to be at peace." Gaius made sure to mention that last part, knowing Merlin as he is he would rather perish but he would never agree to it without the mentioning of the part it plays in other peoples lives.

"I though we were already at peace."

"That`s what they have all of us believing it hurts me to say so but I can't tell you any more than this but I can tell you that if you don`t do something when the time comes a lot of people will die." Merlin wanted to know more, he really did but he decided that trying to make Gaius tell him something he did`t tough he should was a lost case.

Merlin had started packing his things when Gaius approached him with a smile and a white tiny box he held out at Merlin holding it with his right had. "Here." He said as Merlin looked up at him stoping what he was doing he gave two steps forward and took it to open it.

It revealed a ivory colored pearl with a chain attached to it. "What is it?" He asked knowing it had to have a meaning behind it as people did not just go around giving pearls to other people just for the sake of it. "It was your fathers." Replied Gaius. "He left it before..." He trailed of as he made an eye gesture around the place. Merlin was surprised Gaius rarely talked about his parents and that had been twice in a day usually when the subject popped up they talked about it a few minutes and then continued in as if the conversation and never happened. "What does it do?"

"He told me to give it to you when it was time for you to use it." He said glancing at it. "It woks like a card. It contains money limitless at that, you could use it all you want and it would never end and it receives money constantly to. Though don`t ask me how or why it is still a mystery to me to." As much as zMerlin was tempted to mock Gaius and ask why he decided on a real question. "What if I lose it." He then looked worried at Gaius as he realized he was probably going to drop it as soon as he oft the house.

"You can`t, you summon it. Once you place it around your neck it will recognize your fathers blood in your own. It will enter your body and only come out when you command it. You would be an idiot if you were to lose something that`s attached to your body it`s like losing a leg Merlin it just can`t happen." Merlin looked at the pearl amazed as he placed it around his neck slowly and hesitantly. When he looked down at his chest it was`t there anymore. "Gaius is gone!" He shouted.

"I told you-"

He stopped mid sentence when Merlin shouted again. "It came back! I tough it back around my neck and it came!"

He sighed. Merlin was acting like a child that got the toy he asked for. He had to admit though he was radder dumbs trucked it had been difficult for Balinor to summon the thing back it took a lot of magic to do so, even so Merlin did it without much effort. And that was without saying that Balinor was one of the mot powerful demons he had ever known.

"Merlin, before you go tie this." He said handing out a tiny crystal jar with 2 pills in it. "What for?" Merlin asked as he took it to inspect it. "Once you get to hells entrance take the yellow one. It will give you the appearance of a demon during the day in other words your wings will change to those of a demon and your horns will turn black. It will not affect you or your powers in anyway." He added when he saw Merlin`s worried expression. "And the other one?" He asked looking at the blue pill.

"Take that one at night on your first night there. Here me clearly Merlin. Take it at 7:00pm sharp. Take it one minute or a second late and every night at 7:01pm you will have your actual appearance. One hour late and during that hour you will have you actual appearance." Merlin looked at him wide eyed. "Could you make it sound less like a horror story? Seriously Gaius a little bit more and maybe background ghostly music will start." Gaius ignored Merlin and said. "Just don`t take it earlier or later than at 7:00pm."

"Will I get back my original appearance when I come back?" He asked afraid of hearing other wise. "No, there are 3 ways of breaking the enchantment tough. One, if an angel and a demon touch you at the same time. Two, if both you demon and angel sides are equal in power or third if the enchantment is not well made it just docent work so I guess there is only 2 ways..." Gaius trailed of looking at the horror like expression Merlin had on his face. "Oh, but don`t worry that one works just fine; nothing bad is going to happen."

Merlin left out a relieved sigh. "Tough if something does happen you can always just knock out the guards protecting the gates and come back." Gaius surged off. "Gaius!" Despite himself Gaius laughed but reassured Merlin nothing bad would happen, now if he could just also convince himself it may all just look like it indeed was alright.

I hope you liked the first chapter. It hurts me to say so but I won`t be able to up-date frequently but I`ll try to do so as much as I can.

I decided to publish this today since the month of torture has started (don`t take it personally my birth date is in this month yet it has the worst of beginnings -by that I mean that where I live school starts this month and as much as I like it I do not like feeling stressed so I decided to change that by publishing this 2 day and make it all better!)

Review?
