*****
After living through Punchau's horrific memory twice Abigail returned the revolting tome to Dr. Armitage at Orne Library. She offered him any memories he wanted in exchange for more information about the Knife, but he claimed to have nothing else. She spent the next week in a fog, barely engaged with her classes, focused on finding something, anything, new about the ancient relic. On top of her distracting obsession, her sex drive was surging and she spent hours each day furiously masturbating, fighting the desperate craving to impale herself on the handle of the Knife. Part of her mind recognized the increasingly dire nature of her condition, but her uneasiness fled when her pussy began to ache for release yet again. Her roommate Maria had even asked if Abigail was using drugs, and didn't seem to believe her when she denied it.
The orgasms were intense, but the highs faded quickly into depression and anxiety over the Knife. What was it doing to her? How could she control it? Or... could she somehow get rid of it? The mere thought of being parted from the Knife made Abigail shake violently. All her avenues for research had led to dead-ends. Google was useless. The libraries were useless. Miskatonic University's collections were useless. With a desultory effort she posted a picture of the Knife to /r/AskHistorians titled "what the hell is this?" and rolled onto her back to masturbate again.
Abigail's pussy was raw from all the rubbing and her muscles ached from the repeated orgasms, but her primal urges muffled the terror that permeated her conscious thought. Her fingers habitually fell into their rote patterns of motion, and she moaned loudly as the power swelled in her body. The pleasure was intense and joyous, and she longed to linger with it, but she couldn't hold off, couldn't refuse her need to climax immediately. She threw herself over the edge of orgasm and curled into a naked ball on her bed, burying her face in her pillow while she screamed in ecstasy and exhaustion, her cries of pleasure gradually descending into tearful sobs.
When she recovered her senses the sun was drifting downward from his apex and peeking through the top of her window. Maria would be returning soon. Abigail reluctantly pulled on some sweatpants and a sweatshirt and washed her face, hoping to avoid any concerned questioning. When she dropped back down in front of her computer she was surprised to see a private message waiting for her. The mods of /r/AskHistorians had already deleted her desperate post - of course - but someone named RaptorChick had responded almost immediately: "Call me", followed by a Skype contact.
Abigail leapt to her feet and spun around the room in a panic, her damaged psyche not quite knowing how to respond to the sudden development. She started up Skype and bounced back into her seat while she waited for it to connect. She had a few minutes until Maria came home from class. She typed in the Skype address and hit the call button, and decided at the last second to stick a piece of tape over her webcam.
"Hello?" she said as the call set up, surprised to hear her own voice come out as a squeak.
The video window spun for a few seconds and then stabilized to show a woman sitting at a desk in a large corporate office. She was young, maybe mid-twenties, and had long brown hair and sharp features that gave her a precise, symmetrical beauty. She smiled and spoke confidently. "Hello. You can call me Raptor for now; what is your name?"
Abigail was quiet for a moment, but the woman waited patiently. "You can call me... Punchau," she said, surprising herself with the moniker. Why should she use her real name when the woman hadn't?
Raptor lifted her eyebrows at the name and tilted her head, but she didn't drop her smile. "Fascinating. I can tell you a few things about the picture you posted, Punchau, but first - are you in possession of the athame?"
Abigail hesitated again and turned the Knife over in her hands. "Yes."
Raptor nodded. "Excellent. Can I please see it? I understand your desire for privacy, of course. There is no need to show me your face."
What choice did she have? Raptor was her first new lead in a week. Abigail laid the Knife on her desk and turned the webcam towards it, cutting out everything else from its field of view. When she pulled off the tape Raptor gasped. Abigail replaced the tape in a hurry and snatched the Knife back up.
"What can you tell me about it?" she asked.
Raptor was grinning and bubbling with excitement. "What a terrific relic you have there! How long have you had it?"
"A few weeks," Abigail said, then clamped her mouth shut. Don't say too much.
"Well, it's very valuable -" Raptor began, but Abigail cut her off.
"It's not for sale."
Raptor laughed. "Of course not. It belongs to you. With you. I was simply going to tell you that because it is so valuable, there will be people who want to take it from you."
"What people?"
Raptor shrugged. "Even people you trust might become jealous of the athame's... unusual nature."
Abigail growled. "No one can take it from me."
"Quite right. Just a warning. This kind of relic can have unpredictable effects on people around it, inciting strong emotions and awakening latent power." She paused, as if waiting for a reaction, but Abigail was silent. "Apparently you know what I'm speaking of. Not surprising, since you've had it for nearly a cycle."
A cycle of what? That wasn't important. "But how can I control it?" Abigail asked, a desperate edge on her voice.
Raptor grinned again. "By giving in to it. Submit to it. Follow your... urges. You won't be sorry."
Abigail's fingers caressed the Knife in her lap; she knew what urges the woman meant. Take it inside her. She longed for it. Raptor stared at her through the screen, silent, as if sensing her indecision. But before Abigail could act a key turned in the door lock and she lurched forward to slam her laptop shut. She tried to stand, but suddenly her legs weakened and she fell out of the chair onto the floor. Maria stood outside the door in shock, key in hand, and Professor Ward rushed in and descended on Abigail as she collapsed. As her vision faded she heard him say something about "rehab" and saw him dangle a silvery medallion over her head.

Abigail was groggy as she woke up, but her body surged with adrenaline when she realized her arms were bound behind her back and she was lying on the floor. Where was the Knife? She struggled in vain to pull her arms free, twisting and rolling across the floor until her spasms were interrupted by a woman clearing her throat.
"Abigail, calm down, everything is ok," came Victoria's voice.
Abigail took a deep breath and looked around. She was in Professor Ward's office, lying on the rug in the middle of the floor. The curtains were open and late afternoon sunlight poured through the large windows. Heavily laden shelves loomed over her, but the previously cluttered floor had been cleared - the anthropological curios had been plowed into drifts against the walls. Ward's massive desk towered over her, and she used it for leverage to push herself up onto her knees. Victoria sat in Ward's chair, her finger holding her place in the book she had been reading when Abigail woke up.
"Where's my Knife?" Abigail asked, breathless, scanning the room from her knees.
"Professor Ward has it," Victoria said flatly, setting her book down. "Against my advice, he's going to give it back to you."
Abigail wiggled to her feet and strained against the bindings on her arms. Her voice started out calm, but she was shocked as it escalated into a scream: "I want the Knife back right now, or you'll be sorry. No one can take it from me!" She sucked in deep breaths and settled back down on the floor.
Victoria peered at Abigail, as if studying a rare artifact. "I'm already sorry. After what happened to Emma we should have been much more careful with the Knife... but we thought she was a one-off. It didn't affect any other woman like it affected her. Until you."
Most of Abigail's mind was consumed with desperation to reclaim the Knife, but a small rational part whispered, "What happened to Emma?"
