(I think I'm gonna start with the interrogation. Meshnel will handle it. He has an excellent fear factor when he needs to.)

The sorceress sat (sat isn't really a good word but there isn't one.) on the ground, spell-binding ropes tied around her, preventing her from casting a spell. The others watched quietly. They wanted to see the show before turning in.

"So. Any reason you particularly need that demon essence?" he began. She spat in his face. He wiped it off and continued, more firmly. "Why do you need the essence?" She spat in his face again. This time, The spit boiled off, his skin heating as his demon magic did its work. This alone was a bit scary, watching the spit dissipate into steam from his skin. He snapped his fingers and held his hand in a thumbs-up position. A small fire appeared in the area above where the tip of his fingers met the palm, making it look like the fire was sitting in front of his thumb. He slowly, gently, placed the fire on her arm, burning it.

"AGH!!" She growled in pain.

"Believe me, it can get a lot worse. It doesn't have to though if you just tell me what I want to know...." He said, looking down on her. Aner, Rena, and Askurei couldn't help but cringe. They had never seen this angry, almost sadistic side of Meshnel before. It scared them.

"Go to hell..." She uttered, glaring at him.

Meshnel truly scowled, then bared his teeth. And before her eyes, they grew longer. He already had fangs, but now they were an outright mouthful of sharp, painful-looking teeth. His eyes turned completely red, even the whites and pupils, and curving, malicious-looking horns of fire developed on his head. His hair and beard caught fire as well, giving him a very evil, demonic look. His wings sprouted from his back as well, for extra effect.

"Believe me when I say, you do not want to know the power of the Baalrog..." He growled, his voice multi-layering, sounding as if many Meshnels were speaking at once, along with a darker....More sinister voice. "I find it humorous you told me to go to hell..Since that is the place I call home. Perhaps you would like a trip there. I can take you there now, and back, in an instant, and still show you everything..." His every breath let out a small whisp of flame that heated her face, but didn't quite burn. When she managed to remain quiet he placed a hand on her head, and they disappeared, and reappeared in a moment. The sorceress considered crying right then and there.

"Ok, Ok, I'll tell you everything!" she said, tears beginning to flow down her face.
The rest of the interrogation went smoothly, Meshnel learned everything he needed to learn.
(I'll leave the individual information up to Likalmor, since this plot was his idea.)

Adjara sat calmly during the interrogation and watched it calmly before heading back to bed. She hadn't so much as bat an eyelid through the enitre process. However Andrea had been the perfect accommodating audience member all the way, cringing and twitching where things got harsh and leaning in a little when the suspense got the better of her. How much was for acting purposes even she probably couldn't tell. Feanaro had watched silently as well, nodding at certain moments in acknowledgment or agreement with certain methods.

When it was over, Meshnel returned to the group. The flames receeding from him.
"B-but...You're not a Baalrog." Rena stammered as he approached.

"Ahh, yes. I asked Raknasa for a bit of help, as she was being stubborn."

"Well, excellent show. I was on the edge of my seat the whole time." Andrea said, twitching a bit as she remembered the horns.

"Well, lets all get some sleep." Meshnel said, walking over to his place on top of the carriage and laying down. As everyone went to their beds, Andrea went with Aner and Rena to their tent. A short time afterwards Rena was awakened by a soft brushing against her rear. "What's that thing brushing against my ass..." she asked slightly angrily.

"Oh, sorry, that's my tail." Andrea said, moving it.

"I see.....Well.....Wait, why was your tail there?!?"

"It twitches while I'm asleep." she responded, as if that was an obvious answer. Rena went back to sleep, but Andrea didn't. Making sure to cast a spell where they would sleep soundly until morning. "You, my dear Rena, need a little bit MORE ass..." she said to her, as if she could hear, and began to expand her rear until it matched her breasts. "And Aner...Well, I did need a pillow." she said, making her all-around bigger. She then rested her head on her bloated stomach, and her tail once again fell on Rena's ass as she twitched in her sleep. This was a great night. Can't wait to find out what happens in the morning.

Option 1: In the middle of the night, their new sizes affect their dreams, and all 3 of them manage to have a linked dream. The contents of the dream can be determined by the next writer.

Option 2: Similar to option one, only the dream leads to the spell breaking early and they wake up earlier than morning, which leads to them realizing their new assets.
