Chapter One

Alec blinked as he slowly looked around the hallway he suddenly found himself standing in. It was dark, grimy and poorly lit. It all gave Alec an uneasy feeling as his feet started to take him towards a pair of dark double doors.

His heart was beating fast in his chest as he watched as his hand unconsciously reached down towards the door handle. Alec found himself entering a room that somewhat resembled throne room, Alec was thankful it was empty. Alec twisted to the side when movement caught his eye and his breath was caught in his chest at the sight of someone far too familiar.

"Gabriel?" Alec found himself whispering as he hurried over to the cell that was tucked away in the corner of the large room. Gabriel was wearing a dirtied gown and curled up in the far corner of his cell, hair long and greasy as it hung in front of his dirtied face and sewn shut lips.

"Oh, Angel. What happened to you?" Alec clung to the cell bars and his heart leaped into his throat when Gabriel looked up, his eyes flaring up a bright blue-white and Alec felt a pull from his very soul and all Alec wanted to do was tug Gabriel's prone form into his arms and protect him.

"Alec, come find me. Only you can save me from Asmodeus before he takes all of my Grace, hurry Alec." Gabriel's voice rang out through Alec's head accompanied by a louder high pitched screeching noise that had Alec falling to his knees as he sorted through the noises to hear Gabriel's true words.

"Asmodeus? Gabriel!" Alec called out and then suddenly he was yanked away from the room, from the Archangel who he thought was dead for years only to wake up gasping and sweating in his bed in the Institute.

"What the hell? A vision, it's been a while since I had one of those." Alec staggered into his en-suite bathroom to splash cold water on his face. Alec closed his eyes and could easily picture the place Gabriel was being held and before he knew it he was pulling on his clothes and heading towards where he kept some of his weapons in his room. He sheathed numerous Seraph blades of all sizes on his person, shouldering his quiver before he made sure his bow was properly stringed.

"What am I even doing?" Alec muttered to himself as he found himself pulling out his stele. Alec's eyes went wide and if he looked at his reflection he would see they were glowing a bright blue-white as a rune he had seen before appearing in his mind's eye.

Alec's arm rose up and he started drawing the portal rune in the air in front of him, he blinked slowly as a portal spun to life in front of him. Alec pocketed his stele and stepped into the portal that winked out of existence the moment he was fully through it.

Alec landed softly in a crouch in the very same hallway he had seen at the start of his vision before he quickly unsheathed his Seraph blade. He crept towards the double doors at the end of the hallway, following the same path his vision had taken him. He winced as the door creaked open slightly when he pushed open the handle, but the throne room was empty like in his dream.

Still keeping his guard up Alec hurried to the cell in the corner and almost fell to his knees in relief at the sight of Gabriel curled up in the corner of the cell.

"Gabe, I'm here. I'm right here." Alec whispered loud enough to get the Archangel's attention; he almost sobbed when he saw the Archangel's lips sewn shut in person and the look of relief when he spotted the Shadowhunter.

"Once I get this door open we'll get you the hell out of here I swear," Alec said fiercely as he pulled his stele out and carved the unlocking rune on the lock of the cell and let out a quiet noise of relief when a click was heard and the rusted door swung open.

"Oh, you're in bad shape, damn what did that bastard do to you?" Alec whispered as he entered the cell and Gabriel flinched back from him and curled tighter into a ball.

Alec felt there was something lacking from the Archangel and something in his soul cried out in anger, Alec realizes what was missing and his eyes narrowed.

"He took your Grace, well I may not have a lot left but this should help kick start you a bit yeah?" Alec offered, dragging the edge of his blade across his forearm, wincing at the pain letting out a soft noise when white-blue mist rose up from the cut and Gabriel inhaled it greedily through his nose. Gabriel uncurled from the fetal position as he breathed the Grace in deeply. Alec started to feel lightheaded as blood dripped down his arm and made soft plinking noises on the stone floor below him.

"I'll be a monkey's uncle," A Texan accented voice rang out and Alec let out a cry as he was yanked violently away from Gabriel by an invisible force. The cell door slammed shut as he was tossed into a wall on the opposite side of the room. Alec groaned as he landed in a heap before pushing himself up to glare at a man wearing an all-white suit and looking at him with an interested look on his face.

"A Shadowhunter, it has been decades since I last saw one in person." The man commented as he flicked his fingers, Alec let out a choked noise as he was yanked up off the floor and the invisible force tightened around his neck as his toes dragged uselessly against the floor below him.

"Now a Shadowhunter with Archangel Grace inside of him is something I have never seen before, you are a rare one aren't you boy." The man commented as his eyes turned yellow and the irises were slitted in a way that made Alec's heart jerk in his chest as he stared at cat eyes that were far too familiar in a way that hurt his very soul.

"Not just that, you have a familiar aura of magic around you… Oh, I know! Are you my son's latest conquest?" The man who could only be Asmodeus' eyes widened in realization and Alec's heart twisted as he realized this was Magnus' father.

"Then again his aura is weak, he broke your heart, didn't he? Ah, he takes after his old man in some ways then, so I'm sure he won't miss you. I've never tried Grace from a Shadowhunter before, I'm sure it will be a real rush. Pet, do watch and see what happens when you call for help won't you?" Asmodeus called over to Gabriel who was clinging to the bars of his cell, eyes wide and making muffled noises from his sewn shut lips desperately.

The same force that was holding him up off the ground forced Alec down onto his knees and Asmodeus gripped his hair tightly, harshly yanking his head to the side to expose his neck. Alec let out a shrieking scream of pain as a needle was shoved into his neck and a painful pull on his very being started up.

"Oh yes, this will be a potent and powerful mix, I may have to keep you Shadowhunter," Asmodeus commented as he watched the Grace and a bit of blood filled the small tube in the needle he was using to extract the Grace from Alec. Alec's eyes rolled up into his head and felt the wetness of blood trickle out of his nose and over his upper lip.

"STAY AWAY FROM HIM!" A powerful voice commanded as the room shook violently, Asmodeus was forced to step away from Alec who slumped on the floor feeling exhausted and he could barely keep his eyes open to see what was happening.

The bars to the cell had been blown off and Gabriel was stalking forward, eyes flaring with his Grace. All his wounds were gone including the thread keeping his lips sewn shut and dark outlines of his wings flared up behind him as his hair was slicked back to its normal appearance.

"Well, well, pet got some strength back." Asmodeus mocked as he lifted his foot and stepped down on Alec's back making the Shadowhunter cry out in pain as his ribs and spine protested under the sudden and heavy pressure.

"I was right about this one's Grace being a potent mix, I can't wait to test it out myself."

"You won't get the chance," Gabriel sneered as he snapped his fingers. Asmodeus stepped back away from Alec in shock and pain, lifting his hand up he watched as his whole body started to burn and turn to ash from the inside out.

Asmodeus cried out in pain and outrage as with another snap from the Archangel he was destroyed and nothing was left of him, not even a pile of ashes. Alec coughed as his eyes watered and darkness crept into his sight as he looked up at Gabriel and his wings.

"Thank you, Alec, thank you. Don't worry I'll take care of you, you're going to be fine now." Gabriel's promised as Alec passed into the quiet of unconsciousness.
