You grin as the helpless rogue stares at you with pleading eyes, trying to ineffectively create distance between the two of you.

“S-stay back,” she squeaked out, holding her diminutive dagger in your direction. Her hand quivered violently.

“My dear, if you wish to threaten me harm, do try and choose a more imposing weapon,” you said with a laugh. “My purpose here is not to harm you, so please rise to your feet and let us have a conversation.”

The rogue did as you asked, slowly rising to her feet. She cautiously slid her dagger into its sheath strapped to her hip. Even standing, her stature was dwarfed by your imposing form.

“Good girl,” you say. “I knew you were the brains of the party. Your plan was daring, bold enough to take me by surprise. Had you picked better allies, perhaps you would have been able to escape with several bags of valuables.”

The rogue groaned. “I knew it would, if that idiot could just listen for once!”

You closed your eyes and nodded. “Yes, choosing one's friends and allegiances is important. Which is why I come to you with an accord.”

“Accord?” She questioned with a raised eyebrow.

You shot the rogue a toothy grin, baring your fangs. “You see, now I can't simply let you leave. For whatever merits your plan had, you picked a target that posed a substantial risk to you if you failed. Had you tried this stunt several decades earlier, I would have had your corpse dipped in gold and adorned in my treasure room.”

You gestured to several gold statues in your treasure room with a grin, eying the rogue as she gulped and quaked in her boots.

“But today I lack followers with competence that I had in my past,” you continued. “And that is where I could use someone with your brains and cunning.”

The rogue pointed at herself, “Me,” she said meekly. “I am a common thief, I don't know how much service I could be to one such as yourself.”

You laughed as you leered at the small human girl quaking before you. “Yes, in your current form, you would hardly be useful to me,” you said as you walked toward a large shelf on the wall of the treasure room. “But I have solutions to that issue.”

You reached up and picked up a large, intimidating silver dagger, a ruby soul stone embedded in its hilt, which pulsed with magical energy. You grinned as you inspected the blade and turned back to the rogue.

“This blade,” you started, “belonged to a servant I was quite fond of. She was a dark elf, beautiful in form and dangerous in action. She became one with the shadow, wearing it as her veil, and when neighboring kingdoms felt they could spy on me, I sent her to handle them. This blade has been wetted on the spines of many traitors and enemies. When her physical form became frail, I bound her to eternal service within it.”

You held out the dagger to the Rogue, who gazed at the weapon with equal parts curiosity and fear. “If you wield this weapon, your soul will merge with hers, and you will become my loyal mistress of the shadows. Your cunning and wits will be augmented, as will your physical body, and you will be forever bound to my service.”

“And if I refuse?” She asked softly.

“Well, there's always the corpse dipped in gold option,” you replied with an evil grin. “I trust you are smart enough to make the right choice.”

You quickly flipped the dagger, holding its blade gently as you presented the handle to your prey. The rogue nodded with a frown and gently grasped the blade's handle, taking it from your clawed hands, holding it to her face for inspection.

“A wise decision,” you said as she gazed at the soul gem. “Before your transformation, tell me your name so I can let my foes whisper it on their last breath.”

The rogue removed her hood and looked at you, “It’s Svechna, my master,” she replied reverently.

You gazed at the corners of the room with a smile. Shadows unmoored themselves from the piles of gold and various statues of the treasure room and swirled in a circle around the rogue. She soon caught onto the movement, stepping back as the shadows of the room spun faster and faster.

“What is this?” she squeaked, frightened as she stepped back, but found she could not bring her foot down. She found herself lifted from the ground by some invisible ****. She floated up to the center of the room as the shadows rose from the floors and walls to meet her. She clutched the dagger tightly and screamed as the shadows rushed to her and consumed her.

Her form was lost in a dark orb of darkness. The grim cocoon dripped with smoky shadow. You approached it with intrigue, allowing the falling shadow to fall across your claws. The formless void had no texture and elicited no sensation as it poured over you.

Suddenly, the orb pulsed and began to descend slowly. You grinned and stepped back, ready to admire your handiwork as the orb met the floor. You gazed into the void, the darkness flowing down like a waterfall.

In the darkness, a pale hand burst forth. A woman with skin as pale as the moonlight emerged from the sphere, which dissipated and formed a cloak of pure smoky shadow that clung to the woman's shoulders. But for the dark wisps of shadow which flowed over her body, the woman was naked as the day she was born. Fitting for the day of her rebirth. The frail form of Svechna had given way to a gorgeous, imposing woman. You grin as you gaze upon your wonderful creation. Her face is soft with plush, pale lips and piercing blue eyes, which glow like sapphires from the darkness of her cloak. Her head was no longer shaved, and lovely midnight black hair flowed imperceptibly down her back, its lustrous shine the only thing that distinguished her hair from the void she wore. Her former featureless body had developed womanly curves, with perky breasts and a muscular posterior with shapely legs, perfect for perching unseen in the shadows.

The woman stepped forward and looked at her body, inspecting her changed form. A small smile emerged on her lips, and she knelt before you.

“Thank you, my master, this form is incredible,” she cooed in a breathy voice, gazing at you with half-lidded eyes.

You gave her a toothy grin. “I'm glad you enjoy it, my lovely assassin. It suits you well. I have no doubts you are well suited to projecting my will on the land.”

“Of course, my lord. Speak your commands to me, and I shall perform them without hesitation," she replied with a tone of deep reverence and attraction, biting her lip as she gazed into your eyes.

“As a good **** should,” you said as you dropped your loincloth, revealing your large throbbing dick to her. “Your first order is to please me. I want to enjoy your new body.”

Svechna bowed her head with a smile. “Anything my master wishes,” she said before raising her head and sauntering toward you in a sexy strut, swaying her hips performatively with every step. The veiled cloak shifted, forming into dark lingerie, which framed her breasts and pussy wonderfully. When she got close, you pulled her in and kissed her aggressively, pressing her breasts to your chest lewdly, as her left hand grasped and stroked your dick.

You let yourself fall backwards, pulling the pale assassin onto you with your erection pointed to the ceiling. Svechna giggled and rose, squatted over you, positioning her sex above your dick. She took it and rubbed it against her sex. You grinned as your tip grew wet with her juices while a moan escaped her lips.

“You are so big, my lord,” she cooed as she stuck the tip of your dick inside her.

“You'll see how big soon,” you replied with half-lidded eyes. “Now enough teasing. I have graced you with strength, and I want to see you use it.”

“Of course, master,” she replied, and slowly she began to ease herself onto your dick with a throaty moan escaping her lips. You enjoyed her hot sex, squeezing you tight, her new strength demonstrated in the most lurid fashion.

Without needing to use her arms for support, she rose and lowered herself onto your dick expertly. Your hands gripped her perky breasts and squeezed them, eliciting a moan from her as she gazed into your eyes while biting her lip. Her hands grabbed yours, refusing to let you release her breasts from your grasp.

“More, please,” she begged as she continued to push your dick deeper and deeper inside her.

You grinned an evil grin and ripped your hands from her breasts and grasped her thighs forcefully, gripping them tight with your claws. “As you wish,” you bellow as you pull her form down while thrusting into her.

The Woman squealed with delight, her face contorting as you pushed against her G-spot. You began to use the assassin as your personal flashlight, thrusting in and out with passion. Svechna's mouth was **** open to give new screams of delight with every thrust. You enjoyed her velvety insides, squeezing the life out of your dick, **** to coax your virile seed from your loins.

“Oh f-fuck!” Svechna yelled deliriously. You grinned, her insides gripping you like a vice, coating you with moist lubrication. Your own orgasm was fast approaching, and you groaned as you painted the womb of your **** white. You forcefully drove her hips down to meet yours, forcing your seed into her limp body as deep as you can manage, panting as rope after rope of cum entered her.

As your orgasm subsided, you pulled the woman down next to her. Svechna's body quivered with lingering pleasure as you kissed her.

“Your first act of service was acceptable,” you cooed lovingly to her. “I will look forward to using you more.”

“Thank you, master,” she replied in barely a whisper as her eyes fluttered and closed, sleep overtaking her. You inspected her form, happy to have your first servant in so long, her pale skin glistening like the gold coins she slept on.

You would give her rest for this moment. After all, you had her friends still loose in the castle.
