A/N: okay, I was not meant to write another Loki-related fic. But I got the green-light to experiment on this type of character and see how I can write her. This is more like a prologue than a first chapter but hopefully it's interesting enough...
"Nice going, stupid. Fury's gonna get your ass for this." a voice chuckled in her head. "Shut up." she mutters under her breath, reaching between the slit of her black velvet dress and pulling out the hand gun strapped on her leg.
"Coulson's warning was too late. We can't do anything about him anymore." Another voice said, more quiet than the first. The grand foyer below was filled with people running amok in their formal attires. She lifts the gun and aimed at the dark-haired man pinning her assignment on the sacrificial table. "Maybe I can redeem myself if I take out S.H.I.E.L.D.'s number one priority." She says, turning the safety off.
Green eyes suddenly met hers and she felt herself stiffen. She has not been frozen in fear in a long time, especially with the two voices in her head that keeps her on her toes. But the cold chill down her spine was something different, it reached deeper into her. Suddenly, the weapon in her hand had turned into a black python hissing at her. She threw the snake far before it could've bitten her, but instead she sees her gun skittering 15 feet away.
"Illusion." the quiet voice concluded as she spun around back to the marble rails overlooking the floor below, pulling a hairpin studded with rubies from her braid to reveal the blade extending from it. But the man was nowhere to be seen now.
"S.H.I.E.L.D.'s priority is a magician now?" she thought as she kicked her heels off and ran down the steps, taking two at a time. "Be real now. It can't be that simple if the agency is involved." the first voice argued.
Screams almost drowned out the sound of traffic outside. The heat coming from the overturned police car welcomed her as she stepped out of the museum. The tip of a blade tickled the back of her neck as a new voice spoke from behind. "Join your people." he commanded.
At the corner of her eye, she could see flashes of light from the square while people gather themselves in the center with fear. She bit her lip as the voices begun to murmur suggestions in her head. Slowly, she turned to the man behind her, hiding the hairpin on her back, and she met the same green eyes as earlier. Anger builded up inside her as she stared up at the man who foiled her mission. He wore some sort of costume that reminded her of fantasy novels and movies she had seen.
"Okay, possibly a psycho-magician then." the first voice said. She swung her right leg, pushing the spear aimed at her out of the way. She sent the blade flying to her enemy as she pivoted, but it only bounced off his armour. Her bare foot plants itself on his chest, kicking him off as she pulls out a second blade from her hair, freeing her dark locks from the braid.
He staggers briefly, swinging his elbow to strike her before she can use the blade. She felt her weapon leave her grip as she collapse from his attack. She meant to push herself up when he hits the back of her head with the blunt end of his spear.
She grit her teeth, fighting for her consciousness but it was no use. She hears him say, "How unfortunate, you've ruined that lovely dress of yours." before she slips into darkness.
