I've had a few queries on how the characterisation works in this fic, regarding the Supernatural/Merlin crossover. Basically, some characters crossover really well (hopefully you see Arthur like Dean, Uther like John, Morgana maybe as a Sam?) Others, like Merlin or Gwen, are just new characters. They don't really correlate with any Supernatural characters but hopefully they still fit ok in the story? That's the aim, anyway.

This chapter got slightly more dark than I expected, but I hope you still enjoy.

Darkness Descends

The hunters were still stood in horror as a sudden shot rang out in the warehouse, and Morgause stumbled backwards as a bullet hit her shoulder. It was followed swiftly by another to her stomach and the pounding of running feet across the floor. Merlin looked up from the cold floor as he watched Ely run towards them from the opposite end of the room.

'Sir, get away. I've got control of the demon. Get out.' He was fiddling with his gun as he ran and fired it once more, shooting another bullet into the woman's body.

She looked down coolly as it hit her chest, spilling blood down her white shirt. With a roll of her eyes, she snarled, 'I just saved your bloody lives, and this is my reward? Racist.'

Morgause twisted her hand menacingly and Merlin watched as the hunter's head twisted around with a harsh snap, and he fell to the floor dead.

'Ely!' More rapid footsteps as Mordred and Morgana entered the chaotic floor, and Mordred ran to his dead friend's side. He stopped suddenly, and doubled over, coughing up clumps of blood as Morgause glared at him angrily. He fell to his knees heavily, vomiting red as the demon continued to focus on him.

The snap of a gun barrel diverted the demon from Mordred's increasingly weak figure to see Morgana approaching her slowly, gun raised in her shaking hand. Morgause flicked her eyes back to those of her meat-suit, deep chestnut to meet Morgana's peridot, noting a flicker of something across the woman's face as she did so. She turned from Morgana to meet Uther's glare with another cruel smirk. 'You hunters know your bullets won't affect me, right?'

'Our bullets won't, but this will.'

She turned quickly at the unexpected voice as Merlin plunged the knife previously lodged in Cenred's throat into her calf. There was no electric crackling as there had been with him, yet she collapsed to the ground in agony, her hands flying to the knife now residing in her leg. As the demon gripped the wound, Uther motioned to Arthur animatedly, who pulled a burlap bag from his jacket pocket and thrust it over the woman's head. A devil's trap had been harshly painted on the front, forcing the demon to stay motionless as long as it rested over her head. Merlin couldn't help but smile at the ingenious notion behind it.

'Good job, Merlin.' Arthur frowned, clearly impressed yet shocked, and clapped Merlin hard on his shoulder, before looking back at the figure on the floor. 'Shall we kill her now? Ely's revenge?'

'No. We need to take her back to Gaius; she must have had something to do with all this. She'll at least know something. Then, she can pay for death of Ely.' Uther spat at her feet. 'Someone knock her out.'

Morgana's eyes widened as Arthur and Mordred approached the woman. 'No! Arthur, get away from her. She can't go anywhere, isn't that enough?'

'And how will we get her back if she's conscious?'

'Well, how did you get here, because that should help?' From beneath the bag, Morgause's voice was vaguely muffled, yet still enough to dig at Arthur. 'Sit me in your buddy's seat; he's hardly going to be needing it. Though with you hunters and your obsession with dead bodies…'

'Shut it, black-eyed bitch.'

'Does calling every woman you meet a bitch help you, Pendragon? Is your masculinity really that threatened by any woman who isn't some sort of housewife or porn star?'

The blonde snarled and raised his foot, going to kick the demon on the floor, before Morgana grabbed his arm angrily. 'Leave her, Arthur. How much harm can she really do? She's had the opportunity to kill us all, and she hasn't. She can just sit in the back like anyone else.'

'I just saved your miserable arses, I deserve at least that. Bastards.'

Arthur growled furiously and threw another glass of holy water over the blonde woman, who sat strapped into a wooden chair in the middle of the floor. She fought madly against both her bonds and the restraint of the devil's trap on the ceiling above her head. She hissed as smoke rose from her skin when the water made contact.

'Feeling good about yourself yet, Pendragon?' She snapped. 'All this torture making you feel like a man? Like your daddy?'

'What were you doing in that warehouse?' Arthur said, attempting to ignore her and remain calm, yet he felt his voice getting louder with every question. He'd been alone in the room with her for over an hour now, yet no amount of holy water, or slice with her blade, seemed to be making a difference. 'Why were you there? Who sent you there? Why did you kill Cenred?'

'You won't accept saving your miserable lives as a reason?' Morgause cocked her head, narrowing her black eyes. 'No, you arrogant Pendragons, you just can't look past the 'demon' thing, can you? Can't accept that maybe we're not all the same?'

'You killed a man. A good hunter. A friend.'

'Because when someone's shooting at you, I'm sure you don't mind. In fact, I'm sure you're just jumping into bed with them…'

Another glass of holy water caused her to scream unexpectedly. 'I could just exorcise you, bitch.'

'Again with the bitch comment.' Morgause snapped back, before a knowing smile passed across her face. 'Besides, you can't exorcise me. You want information. You think I possess said information. You might be right. But I won't tell you.' This time, he couldn't resist a sharp backhand that had her laughing loudly, taunting him. 'Ooh, Pendragon, that almost hurt. Suppose me protesting my femininity to you wouldn't calm you, would it? Not if you're anything like daddy, he sure loved killing your ickle mommy…'

Another backhand that had her spitting blood this time. Arthur put both hands on the arms of her chair, and leant in menacingly. 'Don't you dare mention her. Don't you dare. You know nothing.'

'Oh.' Morgause frowned as if in genuine shock. 'You mean he hasn't told you? Did he tell you…? No. You didn't believe that, surely?' One look at the confusion painted on the man's face had her laughing once more. 'Oh, you really did? You really believe she was killed by the demon who possessed her?'

'She was. One of you killed her, you black-eyed sons of bitches.'

'Oh yes, because we just love killing our own meat-suits, don't we? We just wander around possessing people and then kill them. How many demons have you met who've done that, Pendragon? Maybe none?'

'No…'

'Your precious daddy killed her. He took a great big knife and hacked at her, over and over and over. Of course, the demon left her as soon as he made the first blow, but he still continued. In fact, he kept at it until he'd cut his own wife's head from her body and his hands were covered in her blood…'

Arthur was suddenly by her side, the knife against her cheek, his hot breath at her ear. 'You say one more word, and I kill you. In fact, maybe I will do anyway. Like you said, you won't tell us anything. What's to stop me?'

He expected her to beg, he wanted to hear her sob, yet she merely turned her head, and grinned wickedly before laughing mockingly. She continued, getting louder and louder until he threw the knife and stormed from the room, slamming the wooden door behind him yet unable to block her cruel taunts from his ears.

She didn't know how long it had been, it could have been minutes, or hours, or days. Not that it really mattered. For now she was watching the door open, edging slowly, almost hesitantly, and the dark-haired woman was entering the room, wide eyes focused on the blonde demon. As their eyes met once more, Morgause smiled.

'I've been waiting for you, Morgana.'
