Moira
Moira felt a pleasure deep within her bones at the sensation of the blood flowing into her body, and it was only intensified by the feeling of her prey weakening slowly but surely. He began clawing at her, and she dimly felt the pain as he left shallow furrows in her shoulders, her arms, and her abdomen, but she paid it no further attention except to note that some of her blood was leaving her rather than entering her body, and this was unacceptable.
So, instinctively, she pushed the pleasure his blood was giving her into his mind, until his unprepared mind was consumed with it. His struggles weakened after that, and soon the strength in his body began to abandon him as well. Though he continued trying to drain her qi, she was now passively absorbing more than he could take, and the qi within him could not fully make up for the blood loss.
Eventually, the demonic cultivator fell to his knees, and Moira took advantage of his weakness to push him fully to the ground. Her mind was fully lost to the pleasure she was feeling, so she didn't even notice when another demonic cultivator stepped through the same portal, one slightly stronger than the one she was currently feasting on. He was temporarily stunned by the killing intent he was feeling, and he was horrified when he realized it was coming from the young girl currently draining his fellow cultivator.
Before he could take a step, he was even more horrified to witness the sight of the skin of his sect mate slowly becoming more pale and dry, as the muscles underneath slowly withered. Moira didn't stop even at this development, and deep within the first demonic cultivator, the blood was being pulled out of even his internal organs, mummifying them in the process. Despite this, his heart kept on beating until the very end, as his cultivation base was able to keep him alive even through fairly heavy blood loss.
Moira finally stopped when she no longer felt that she was absorbing blood and she heard his pulse come crashing to a halt. However, rather than feel sated, she only wanted more, and as she rose to a kneeling position she saw a new prey before her and gave a demonic grin, only enhanced by the blood around her mouth.
The new demonic cultivator gave a cry of rage, removed a sword giving off a creepy aura from somewhere on his person, and charged Moira without further warning. Moira calmly found her feet and at the very last second slapped the blade of her new opponent aside so that instead of neatly slicing her in two, it missed her entirely by a few millimeters, and crashed into the ground, where it became stuck.
Without waiting for a further invitation, Moira jumped up and wrapped her arms and legs around her new victim a little like a Koala while she sank her teeth directly into his neck. Her mind immediately began bombarding him with the intense pleasure she was feeling, and combined with his rapidly draining strength, he failed to put up much resistance before falling to his knees as well.
Soon, Moira also had him on the ground while climbing on top of him, and a new sect mate walked through the portal. However, after evaluating the situation, he turned around and exited that portal with the same degree of haste.
Moira had just finished off her latest victim and was beginning to lose her mind to rage because there was no more prey when the third man walked back in with another at his side. She took note of her prey, and dimly within the parts of her mind that were still functioning, recognized that she would have to find a way to prevent one of them from intervening while she consumed the other.
Instinctively, without even really thinking about it, she drew the slightly curved sword of her previous opponent from the ground and sent a swordlight of holy and demonic qi flowing directly through the chest of the man who had come to back up his friend. He looked down at the hole where his heart used to be, and fell while clutching at it.
After his collapse, Moira discarded the blade in her hands which had begun to disintegrate from the incompatible technique she had used and immediately rushed the surviving cultivator. She was on him before he could fully react, and she bound him to her using the same force from before.
She had fully managed to drain this prey when a new force walked through the portal, seven cultivators that were clearly of a higher level than the previous 4. After taking a look around at the situation, they immediately began throwing techniques to capture and bind her without hesitation.
Moira moved surprisingly swiftly, and she led them on a merry chase for many minutes before they finally managed to seal her inside a domain, which meant that they would soon have her in chains.
It took three of them to hem her in and bind her with chains strong enough to hold her fast, and once they did so, they barely breathed a sigh of relief when they heard a shockingly loud booming noise from outside in the hallway. They glanced uncertainly at each other, and jumped slightly when the noise repeated itself, followed by the sound of metal being pushed to its limit.
Meanwhile, unbeknownst to these poor cultivators, Moira had begun devouring the demonic qi within the chains that bound her, and was fairly rapidly converting it to spiritual qi within her body. At the same time, a strange black rust was rapidly consuming the chains themselves, as though they were experiencing the flow of countless years rather than the passage of time of just a few moments.
Just as 4 of the cultivators split off to see what the ruckus was outside the door, three remained behind to guard Moira. They decided to torment her for what she had done to the other cultivators, and soon weak swordlights had cut most of the rest of the clothes off of her body, leaving her in just her boots and panties. Of course, they had also drawn thin cuts along her skin, so she was bleeding freely from areas around her hips, shoulders, chest, thighs, and calves.
Before they could continue amusing themselves with her suffering, she flicked her wrists and the chains binding her collapsed to dust. They all took a step back, wary of anyone who could successfully escape such a thing.
She rose to her feet, and rather than conjure any special strategy, she charged at the nearest of these demonic cultivators like a vengeful banshee, and began draining him with record speed. The others were too shocked to intervene at first, and before they could the booming resounded again followed by what sounded like an incredibly strong metal shrieking in protest.
Moira's latest victim was not fully overcome with her killing intent nor the pleasure she was bombarding him with, but his efforts at resisting her soon proved futile all the same. Finally, the other two cultivators began beating her and grabbing at her limbs in an effort to remove her from the body of their peer, but though she did bruise rather nicely, she gave no sign that she noticed their efforts at all.
They noticed with horror that their companion was slowly mummifying before their eyes, and there wasn't much they could do before the process was complete, at which time Moira stopped resisting them entirely. They flew backwards about 10 feet, and Moira landed on all fours before recovering to a standing position. She turned to face the two remaining prey in this room, and rather than charging them, she raised her right hand palm out and cried out, "Bleed for me!"
The two noticed with horror old wounds beginning to open on their skin, including countless injuries that had been forgotten from practicing the blade and from the feeble resistance of previous victims. As more and more time went on, more and more of these injuries opened up, and from all of them their blood flowed out freely, defying gravity and sense to flow directly into Moira's palm where it was absorbed by some unknown method.
The two demonic cultivators tried spreading out to hopefully force her to target them one at a time, but inexplicably this had no effect, and their wounds kept opening even as their blood kept flowing. Meanwhile, the originally dim life force of the sickly looking girl grew brighter and brighter as her skin began to heal all of its injuries and glow with a healthy sheen. Her body also began to fill out slightly more, and instead of slightly malnourished she now just looked a little underweight.
Rather than just accepting defeat, one of the two demonic cultivators rushed to her and began trying to draw her spiritual qi from her lips once more, in a desperate bid to kill her before she killed them. His efforts were far more efficient than those of his predecessor with the same idea, and though he failed to save his life or that of his companion, he did manage to induce qi deprivation inside Moira.
The young girl remained kneeling on the floor there for some time, a trickle of blood flowing freely from her lips as bruises continued to develop all over her body. Her eyes were glassy, almost as if she had no awareness of her surroundings. Her upper body was completely bare to the environment, and she shivered slightly beneath the cool airflow of the ventilation system.
