Let's see, wounds caused by Meligaunt's sword doesn't heal.
And given it is part of the Arthurian cycle...well, after his little...affair...with Morgana...I can see my furious making sure Arthur won't be able to sire children ever again.
The best thing? Merlin's magic will be ineffective in...restoring...Arthur to his old self.
I won't clog this thread with any big fanfic, but I admit I was thinking if Guen faces the situation with Arthur. Obviously this isn't canon.
Guen sighed, running a hand through her hair. She was finally done with the last supplicants after she held court, and as usual Arthur was nowhere to be seen.
Because he has better things to do, she grumbled to herself. However, her frown lifted now that she could spend a little time to talk with Morgana who had arrived earlier that morning. Ever since her wedding day, Morgana had been her most steadfast friend in Camelot.
Guenevere moved down the hall, briefly pondering where her sister-in-law could be, when she heard the pitter patter of little feet. Unconsciously, she bent her knees slightly to give her fae cat a scritch behind his ears. Her smile widened as Sir Fluffy's purrs echoed in the hall.
"I'm glad I could brighten someone's day," Guen said teasingly.
As if remembering something, Fluffy leapt forward, and turned his head, looking at Guen questioningly, "Rowr?"
"Something the matter?" she asked.
"Merowr!" Fluffy replied. With one paw, he snagged the hem of Guen's dress, and started to pull it forward.
"Something you want to shw me?" Guen asked, wishing she had taken Merlin's offer to learn how to brew a speak to animals potion.
"Meow!" answered Fluffy positively, and he started to pad toward her bedrooms.
Guen's eyes narrowed as she remembered the last person to enter her room uninvited: Sir Meligaunt. Her hand dropped down to Widowmaker, the name she gave to the sword which formerly belonged to Meligaunt. One cut from it, and the wound would never heal.
She quickly chased after her cat, making only one stop with a passing servant, telling him to find Lancelot, and rouse some of the palace guards. Satisfied with her plans, Guen closed the distance and saw her bedroom door was closed. Quietly, she put her hand on the handle...only to find it locked. Then she heard some high-pitched cries from in there, one of which sounded like Morgana.
"Fluffy, break it down!" Guen ordered.
"MEROWR!" roared her fae cat, growing until it was larger than the biggest lion, and smashed through the door. Guenevere quickly followed behind...only to come to a halt as she saw Arthur and Morgana in the same bed, blankets wrapped up tight and covering their nakedness.
"What is the meaning of this?" Guen yelled, her voice matching Fluffy's from just a moment before.
Arthur raised up a placating hand, stammering "I can explain..." while Morgana blushed, and pulled the blankets over her head.
"Explain? There is no explanation for defiling our marital bed!" Guen growled in rising fury. She pulled out Widowmaker, it's edge glowing red, its malevolence matching her mood.
Arthur rolled out of the bed, his hand reaching out for his scabbarded sword...only to meet with air as Fluffy darted faster than any human could, and batted the blade aside...and out the nearby window.
"Guen, please...stop...please," cried Morgana from the right side of the bed.
"Don't worry, I'll attend to you next," Guenevere said, keeping her eyes focused on Arthur. Guenevere circled her husband, calculating his most likely defensive move when shouts filled the hallway. Suddenly Lancelot entered the room with several guards, and assorted castle stuff on his heels.
"I'm here," Lancelot then shutting up as he took in Arthur and Morgana's nakedness. Then his eyes saw Guenevere's sword raised high and the fury on the queen's face.
"Put down the sword," Lancelot taking a tentative step forward, but stopping when Fluffy hissed at him.
"Why should I?" Guenever said, her eyes still focused on Arthur.
"Because I don't want you to die for regicide," Lancelot said quietly. He glanced at his best friend and the step-sister, "I...I can see they have dishonored you, and they will pay for it...but not this way."
To Arthur's relief, Guen lowered her sword. Sighing, she sheathed her sword, though she could feel a wave of disapproval from Widowmaker, disappointment that its thirst for blood won't be filled this night.
"Throw them both in the dungeon," Guenever said.
"You...you can't do that," uttered Arthur.
"Oh yes I can," Guenevere smiled bitterly, "You might be king, but you are still bound by the laws of the Goddess. And this, my dear husband, counts as adultery. There are more than enough witnesses to attest to that."
