Team up.

The offer was tempting. A well of untapped power would await her if she teamed up with the presence in her mind. There was risk, sure. The presence could be lying, attempting to trick her into handing it control. Sarah had bargained with dark powers before. But she always came out on top, emerging stronger after the fact. Perhaps this was just the next logical step for her. And she had to admit, cumming with both her familiar pussy and her new appendage at the same time felt amazing. She made her decision.

'Fine' she said in her mind. 'I accept. But if we're going to do this we need to set some terms.' She felt a sense of acknowledgement from the presence. 'Firstly. You will not be taking over my body again. I want to be in control.' The presence responded: 'We will not do so without permission unless your life is threatened.' Sarah nodded. Having someone watch over her while her consciousness slept, didn't seem like a bad idea after all.

'Second,' Sarah communicated to the presence, 'You will share all you know with me. You can see everything in my mind. It's only fair if I know what's going on in yours.' Once again, Sarah heard the thoughts echo in her head. 'Done. Though we must admit, we don't know much of what we are. Everything we did up to merging with your mind is a blur. We believe our previous form was not capable of complex thought. It is only when our tendrils reached your brain, that we stopped acting purely on instinct.'

'Lastly,' Sarah thought, 'I need your promise that your allegiance lies only with me. Whatever creature you came from, whatever master you might have had before, your loyalty to them ends now. And to ensure it, we will enter a magical contract together. As soon as I'm able to get back to my stuff, I'll draw one up. So. Do we have an understanding?' The presence responded: 'We have a deal.'

Sarah smiled, happy that she managed to take control of the situation again. 'Now, any ideas on how to get rid of that annoying druid? With him out of the way, his sleeping patients should be ripe for the taking.' Sarah felt the presence dig through her mind until it reached something buried within her immense knowledge of dark arcana. A thought rose to the surface.

Night Elf druids were deeply connected to their Emerald Dream. Some even slept for hundreds of years, wandering the natural dimension in their mind. If Sarah's hunch was correct, the druid was connected to the Emerald Dream right now which would explain his meditative state. Sarah knew of a spell that could be used to enter someone else's dream. Her body would be vunerable though, with her mind inside Fendoriaen's dream. Luckily she had the perfect solution for that now. Her new ally.

'Will it work?,' Sarah asked the presence mentally. 'I can hold the fort while you travel inside the Dream. But I can't help you in there. You need to find a way to take care of him. According to what I found in your mind, Druids are at their most powerful in the Dream.' Sarah smiled. 'I've got a few tricks up my sleeve. It should be easy enough to win his trust. And when he least expects it, I will wrench his soul from his body.' Sarahs smiled maliciously as her cock hardened at the thought.

Sarah started making the neccesary preparations. The spell wasn't complicated, but it required the two participants to be in close proximity. She didn't want to be found naked and covered in black cum if anyone entered the room while the spell was in effect. For that reason she decided to clean herself with her own washbasin and cloth and put her robe back on.

She slowly opened the door to the central room, creeping towards the centre where Fendoriaen was still sitting. He hadn't moved even the slightest bit since Sarah last saw him. She pulled a cushioned chair close to the Druid and sat down, making sure her body was in a comfortable position. The ritual called for a whispering chant. Sarah whispered a few arcane sentences as she felt her body get heavier. Another few sentences and her eyes fell shut. And as she spoke the final words, the warlock fell into a deep slumber.
