After All This Time: Revenge

Chapter 2

Abandoned Warehouse, Near Los Angeles, California

The cool night air caused goosebumps to form on her skin. Peeking out from behind a dumpster, the black-clad woman gave a signal to the group of men gathered behind her. Silently, she led her squad to surround the dilapidated building, at least two men covering each exit and about a half-dozen following their leader to an entrance on the side, lit only by a buzzing, flickering light. Without making a sound, she counted down on her fingers.

Three… two… one.

One of the men kicked down the door, surprising the lab-coated scientists inside. Before they could react, the rest of the heavily-armed squad burst in, one group ushering the scientists to the center and surrounding them and the others beginning a sweep of the facility. The woman in black entered as well, her eyes taking in the scene.

State-of-the art machinery lined the walls, screens blinking with different messages. One monitor contained the silhouette of a person, several areas on the body coded with different colors. The words "Subject Terminated" flashed in red across the top, causing bile to rise in the woman's throat. Her eyes narrowed to slits as she approached one of the scientists, grabbing him by the collar.

"Where are the children?" she snarled, cocking back her arm in preparation for a blow if she didn't receive a satisfying response.

The scientist, taken off guard, stuttered, "I- I don't know what you're talking about!"

"Wrong answer," the woman hissed, striking forward with enough force to break the man's nose. The scientist cried out, doubling over and clutching his throbbing nose, blood dripping through his fingers. The woman nodded to one of her own men, who grabbed the scientist's left arm and twisted it behind his back. She ran her fingers through her sleek black hair, attempting to control the rage that fueled her.

"I won't ask again. Where. Are. The children?!" The man's response was to spit blood at his interrogator, his own eyes narrowed in contempt. The woman nodded once more to her guard, and he began twisting the scientist's arm further. As he felt muscles tearing and bones beginning to crack, the man screamed in pain.

"Okay! Okay, I'll tell you!" he relented. The guard released his arm, and he fell to the floor, gasping. "They're… they're in the basement."

The woman felt a smug satisfaction. These people could put on a show of resistance, but they were unused to pain. A mere show of force always broke them. "Where is the entrance?"

"In the hallway, third door on the right. But the door has reinforced security. You can't get in without a fingerprint and retinal scan."

The woman flashed a smile that sent chills up the man's spine. "Well, thanks for volunteering." With their key in tow, she led a small contingent of her men to the door. With a shaking hand and the threat of more violence hanging over his head, the scientist scanned his fingerprint and retinas. Without wasting another second, the woman took the stairs two at a time into a dank, musty concrete room, the only light coming from the hallway at the top of the stairs. Huddled in every corner were children – boys and girls of every age covered in blood and grime and bruises, wearing clothing too threadbare and tattered to offer much warmth. The appearance of a stranger caused them to shrink back in fear.

The woman allowed herself only a moment to grieve over the scene before jumping into action. "It's alright. You're safe now." She sent one of her guards up to lead the medical team down before beginning to make the rounds herself. With each face she passed, her heart tore further in two. Many of the children sported chemical burns and lacerations. A few seemed to have gone blind or deaf. Every one had pain in their eyes. She had no idea how long they had been in this hell, and she only wished she could have gotten here sooner.

Outside, swarms of scientists and security personnel were being taken into custody, red and blue police lights piercing the otherwise dark night. As the woman prepared to make her exit, she felt a small hand clasp her wrist. She turned, looking down at a young girl wrapped in a blanket, her blue eyes big and pleading.

"Wait," she said quietly, her voice hoarse from misuse. "Who are you?"

The woman smiled warmly, gently ruffling the child's matted brown hair. "You can just call me N.C." Before anyone else took notice of her, she fled into the night.

It wasn't until she reached her van, parked half a mile away by a river, that she removed her wig and shook out her blonde hair. Reaching into the glove box, she retrieved her personal cell phone, checking the new message she had received while she was on her mission.

Krista is doing well. When are you coming to visit? She misses you!

Smiling to herself, Adrena Lynn typed a reply. Soon. Tell her I miss her too!

Starting the engine, she peeled away into the night.

Training Facility, Site Beta, Location Classified

"Begin."

Taking the cue from the robotic voice, Krystal entered a room in the training facility she had never been in before. It was dark, light dotting only a few areas of the multi-leveled arena. She took a moment to take in her surroundings, focusing her energy on separating her astral body from her physical one. She closed her eyes and watched as the room unfolded before her, as if she was seeing everything from a first-person view in virtual reality goggles. Her astral projection allowed her to move throughout the facility in stealth mode, her physical body staying put. In this way, she took in the facility – high ceilings, several metal bridges crisscrossing above her; concrete floors that were divided into a maze of hallways and rooms by thick walls; and – there. Several cameras punctuated the junctions of the walls. She ended the projection, able to see once again through her own eyes, and slowly walked forward towards the first turn. Stopping just before coming into the camera's field of vision, Krystal took a small remote from one of the pockets of her utility belt, aiming it at the recording device and pressing a button. The camera emitted a low beep – so quiet, only Krystal could perceive it with her enhanced hearing – indicating that the frequency had been corrupted and the camera would no longer record her movements.

Krystal moved through the maze with amazing stealth and speed, efficiently cutting off every camera she found. As she entered the third room, however, she made a fatal error. When she turned the corner, she was faced with a wall of heavily armed, highly trained guards. Krystal cursed under her breath as she took a battle stance, furious with herself for forgetting to use her aura sense to detect the presence of living beings nearby.

In a matter of seconds, the men attacked with brute force. Krystal skillfully evaded their blows, returning each with one of her own. As she sent one of the men flying with a carefully aimed kick to the abdomen, she focused her energy on her powers, a blue glow engulfing her and growing brighter between her hands. She lunged forward, thrusting her arms outwards and towards the largest group of men. A terrifying beam of pure energy shot towards them, too fast to allow any of them to move out of its path. The beam connected with its targets, the shockwave sending the men sprawling. Krystal had produced just enough energy to knock them out, not kill them.

Before she could turn and face another wave of foes, however, Krystal was kicked from behind, the blow cracking several of her ribs. She gasped, quickly generating a healing aura around the injury. The move slowed her down, however, and another blow was not far behind. She screamed as a knife sliced into the skin on her side, blood already staining her black combat suit. As she searched for her attacker, her arm was grabbed and twisted sharply, breaking the bone. Black dots danced in her vision, and her arm hung at an unnatural angle. Attempting to focus her energy on healing the injury proved futile, as the guards gained the offensive once again. Gritting her teeth, Krystal attempted to fight back, but could not block as many blows as before. She was felled when one of the larger men planted a kick to her stomach, knocking the wind out of her and sending her sprawling on the floor. Before she could stand, she felt a jolt as two sharp prongs embedded in the skin of her thigh, sending waves of electricity slicing through her every nerve. She convulsed, her vision swimming and her powers disrupted, as the bright overhead lights switched on. She rolled to her side once the electricity faded, coughing up blood onto the ground.

Fukushima entered, his hands clasped behind his back, a dark look on his face. "You did not use your aura sense. If you had thought before you acted, all this pain could have been avoided."

"No shit, Sherlock," Krystal rasped, propping herself on one elbow while holding her abdomen with her left hand. She ripped the prongs from the taser from her thigh. With the threat of danger removed and her mind beginning to clear, she focused on her injuries, the blue aura once again seeping into her body to heal her.

"We shall do this again," Fukushima said as Krystal slowly stood. She held up one index finger, placing her hands on her knees to catch her breath.

"Just give me a minute." Fukushima pressed the button on his remote, electricity once again soaring through Krystal's veins. She screamed, her hands latching on to the ever-present collar around her neck.

"No, Imposter. We do this on my timing. Again." He walked away without a second glance, and the lights faded once more. Krystal was given but a few moments to catch her breath before the guards entered again.

Two grueling hours later, she nearly crawled up the stairs to her quarters. Taking one step inside, she collapsed, her hand clutching her heart, her breath coming in quick, shallow bursts. It felt as if her chest was tightening, squeezing her most vital organ until almost nothing was left. Black spots formed in front of her eyes, Krystal attempting to generate another healing aura, before darkness overtook her completely.
