Never really seen the marks given in the books I've read to someone who's willing and wanting and without a third person so sorry if it isn't right.

Chapter 4

"You mean…you want me as your Human Servant?" Harry asked, surprised and curious, and Asher nodded solemnly.

"You are my friend Harry, my brother. If there is something I can do to keep you alive I will do it," Asher swore and Harry swallowed.

"What exactly would it mean?" Harry asked and Asher relaxed a little, it wasn't a 'no' after all.

"There are four 'Mark's involved. With all four we would be tied together for life, you would be stronger, immune to many poisons, a faster healer. This could save you."

"Or drag you down with me," Harry whispered in horror. "No Asher, I can't…"

"It is my choice to make Harry. You are my friend, my brother; I do not wish to lose you. I can give you a chance to survive against this monster. I am over four hundred years old petit sorcier; if this kills me I have had a long existence," Asher reasoned, and Harry just stared at him in shock.

"You mean it….even though you might die….." Harry whispered in awe, and Asher nodded solemnly. "What will this do to me?"

"You will be almost as immortal as I am but still human. Your magic may even increase in strength," Asher explained, and Harry sighed, curling closer to Asher, knowing he'd fed because he felt warm.

"I don't know Asher, if it works and I survive…out living everyone I know….."

"You may do that anyway my Harry. You are very powerful, that will extend your lifespan further than your peers," Asher argued, and Harry nodded, that was why Dumbledore had outlived most of his peers, before looking at him.

"Okay," Harry whispered, and Asher stared at him, feeling a flash of hope.

"Okay? Then you wish to do this?" Asher asked and Harry nodded, making the vampire smile wide enough to flash fang.

"So what do we have to do?" Harry asked nervously.

"It will not hurt petit sorcier; you will not even notice the First Mark. I will shares my life essence with you. The first mark grants greater endurance, healing, speed and resistance to vampire mental powers, and an almost complete immunity to mine. The Second too will require nothing from you, it allows me to draw power from you, to experience food and drink you consume, and to enter your dreams. The third mark is made by my drinking your blood. It will grant you full endurance and allows us to communicate mentally even when awake."

"Let me guess, for the Forth I get to drink yours?" Harry asked, he knew enough about the theory of magic to figure it would have to be an exchange.

Asher nodded in agreement. "For the fourth you must drink my blood, cementing our bond. It conveys immortality to you, almost complete mental communication, and allows you to draw on my strength."

"Okay, so we do this here and now?" Harry asked and

"There is one other thing, the Marks and my powers….." Asher trailed off, not wanting to say it. While Harry was growing into an attractive young man, the idea of sex was not something he would ever consider with him. He was thankful he did not hold the Ardeur but there was still the power of his bite to be concerned about.

"Your powers are based on… oh. That'll be awkward" Harry admitted, blushing slightly, and Asher hugged him, smiling when Harry curled into him again.

It felt good, to be close to someone again after so long. Ever since her death, he had totally cut himself off, unwilling to even try opening up to someone. Those who saw his scars either scorned or pitied him, Harry hadn't even flinched. He'd even offered the hexes he knew against those who had hurt him if it had been recent. Harry may be young, but he had been hurt too, orphaned as a baby, abused and ignored by his family, adored and then scorned by his people and now on the run. They were both damaged but thanks to Harry he was learning to heal, and he hoped he was helping Harry too. "It may not happen; Juliana and I had a very different relationship to what ours is," Asher told him, and Harry took a deep breath.

"I don't want to die Asher and I trust you; I want to stay with you," Harry whispered in acceptance and Asher nodded. "Then let's do this." Harry met Asher's eyes and Asher reached for Harry, giving him the First Mark. Harry shivered slightly; eyes wide. "Thought you said it's unnoticeable."

"To my knowledge, no one has ever taken a Wizard of your kind as a Human Servant; perhaps your magic allows you to feel it," Asher offered, and Harry nodded. "Are you ready?" Asher asked and Harry nodded only to tense as two flames the same colour as Asher's eyes appeared and moved closer.

"Asher?" Harry asked, licking his lips nervously, and Asher cradled him close.

"It is alright, relax and let it happen," Asher whispered, and Harry gasped as he looked at Asher through a veil of blue flames but then they faded away. Harry clung to Asher and the vampire gently ran a hand through the messy dark hair, soothing him.

"So two down?" Harry asked shakily, and Asher nodded.

"We do not need to finish this right now. We can wait," he offered gently. The Marks were usually spread out over at least several days, even months.

"No," Harry answered, and Asher admired his stubbornness, life with Harry would definitely not be boring.

"Very well," Asher agreed, gently pushing Harry back to lie on the pillow.

,,,,,,,,,,,,,,,,,,

Harry tensed but then relaxed and turned his head, exposing his throat. Asher gently stroked his throat and Harry gradually relaxed, closing his eyes, so Asher leant in and bit down as gently as he could, trying to hold back the usual effect of his bite. Harry bit back a moan of pain and then gasped as his body began to react to Asher's power before memories washed over him; he was seeing Asher's memories! He could feel Asher! He held tight to the sheets, breathing heavily as he felt the pull of blood from his throat. He'd never experienced anything like it before, definitely way better than a basilisk bite!

Asher eventually pulled back and they just stared at each other, vampire power and magic swirling around them. Harry's magic reacted and the bite healed over quickly to their surprise, but Asher smiled, happy that Harry would heal so fast. "Are you alright?" Asher asked and Harry nodded, smiling at him.

"I feel incredible." Harry admitted. "So my turn?" Harry asked and Asher nodded. "How do we do this? Last time I checked I don't have fangs," Harry pointed out and Asher chuckled. He got up and came back carry a small silver knife. Harry took it and stared at him. "Where?" He asked and Asher unbuttoned his sleeve, rolling it up. Harry took a deep breath and cut into the flesh of Asher's arm, watching the blood well up. He looked up at Asher who nodded and then lowered his mouth to the wound. He licked hesitantly and pulled a face at the coppery taste, but forced himself to seal his lips over the wound and drink. He really didn't see the appeal in drinking blood, forcing back the urge to gag but then he felt it, power swirling through the room. He gasped as he felt his magic surge through him, feeling stronger than ever.

"Blood of my blood, flesh of my flesh, two minds with but one body, two souls wedded as one." Asher spoke as Harry drank and then power in the rom exploded. Harry pulled off the wound, blood coating his lips as he stared at Asher, feeling the Marks fully form between them as Asher closed his eyes, obviously seeing Harry's memories. Harry slumped against him and Asher held him close, just revelling in holding his new Human Servant close. Eventually Harry sat up but leant against him.

"Wow," Harry whispered, breathing heavily as he struggled to bring his magic back under control before something started floating or changing colour or even blew up.

,,,,,,,,,,,,,,,,,,,,,,,

Asher laughed. "Oui," he agreed, revelling in the newly formed bonds. And then Harry screamed, spine bowing, eyes wide in agony. Asher moved, holding him as he thrashed, trying to claw at his head. Asher pinned his hands as gently as he could, trying to call to Harry but the teenager didn't respond. Asher felt it then, an oily darkness trying to consume his Harry. He gathered all the power he could and threw it at the darkness, he would not lose Harry, not like he had Juliana. Harry grabbed at Asher's hands, panicked green meeting blue before rolling back as Harry's magic latched onto Asher's and then railed against the intruder. Their combined power ripped through it, destroying it and Asher stared as an inhuman shriek came from Harry's famous scar, before black, tar-like blood oozed from the wound until finally clearing to normal red blood. Harry's back arched and he screamed before slumping to the bed, unconscious. Asher used all of his speed to go and get a damp cloth to clean his face before tossing it aside.

Asher lifted Harry, cradling him close, using his presence and the Marks to ground the young Wizard, hoping it would help. Dawn was approaching and there was nothing he could do, he would be dead for the day soon, leaving Harry alone and unguarded. But when the sun rose nothing happened and Asher stared down at Harry in awe. Had Harry been powerful enough to give him this? Was he now a Daywalker? None of that would mater to him unless Harry was going to be okay.
