Yes, I ship these two. Yes, it's because of that one joke... or so it started. The pairing name is definitely ShumaMorri.
Almost as soon as Morrigan emerged onto the lower plane, a dull pain came over her, in body and soul. She inhaled, taking a moment to adjust to this kind of reality.
"If you can hear me, I ask that you come and face me," Morrigan called out, her voice echoing across the wasteland.
After a moment, the old one himself appeared from nowhere, a short bit away from her.
"Why have you come, Lady Morrigan?" Shuma-Gorath demanded to know.
"It's simple. Your tentacles interest me, Shuma-Gorath," Morrigan said with a smirk, accentuating the word. Shuma-Gorath blinked. "What do you say?"
"Certainly," Shuma-Gorath answered, after a pause. Four of his tentacles wrapped around her arms and legs, meeting no resistance. "I should mention that I am fairly out of practice, though I will try not to disappoint," he said, a bit embarrassed.
"Oh, don't worry about that. I am not soon satisfied," Morrigan replied coyly, her accent prominent in the sentence.
"Perhaps we should relocate to your castle, then," Shuma-Gorath suggested. Without warning, Morrigan saw her surroundings shift, into a corridor in her castle. The ancient demon released her, watching her expectantly.
"Follow me," Morrigan said and took flight.
Morrigan awoke. Drawing a slight breath, her closed eyes squeezed further shut. She shifted slightly in drowsiness and hatred of the morning, then turned over.
After twenty minutes, she sat up in her bed. The first thing she saw was what she had already figured - she was alone. The second was the tattered remains of her outfit, scattered around the floor.
"Good morning," she heard from behind her. She turned to see Shuma-Gorath floating on the bed's right side.
"Likewise," she replied. "Although I'm surprised to see you're still here."
"I thought it would be rude to simply leave," he answered matter-of-factly.
"Something of a gentleman, I see," she remarked. "Not what I expected from your horror stories."
"Yes, well, I find it disingenuous to exercise proper manners on the battlefield," Shuma-Gorath explained. "In a mundane situation, I imagine you might find me more pleasant."
"I do so far," Morrigan said with a smile. "I might even go as far as to say that we're beginning a friendship here."
"With a little luck," Shuma-Gorath agreed.
"Anyway, what do you do to fill your days, in your dimension?" Morrigan inquired.
"Whatever I feel like at any given moment," Shuma-Gorath replied. "I admit, this is the reason why I accepted your request."
Morrigan smirked. "Is that an admission of desire I hear?"
"But of course," Shuma-Gorath affirmed. "Though it might be obvious to say, you are a remarkably charming woman, Morrigan." Shuma-Gorath's tone made it sound a simple statement of fact, not a compliment.
"I know," Morrigan replied with a smirk. "Anyway, I would like to receive another visit from you. Let's say, in a week's time?" Shuma-Gorath gave his assent to that.
