As he was thinking about this all night long, some few days before his father's big wedding, his Gwen came into his room and confessed to him :
"Oh dear, dear Mordred. How I've missed you!"
"I've missed you more than you missed me, Gwen. But now you're my Father's betrothed, you can't see any other men, don't let them catch you."
"Oh they won't catch me, my betrothed your father is out there hunting with his Knights."
"Oh yes, the Knights, how I hate them, particularly that vain Sir Lancelot."
"You mustn't hate him, he's your father's best friend."
"I don't care, he humiliated me at the betrothal ceremony, he must pay for it."
"Mordred, he must pay? Since when did you get such thoughts about things and people? He hasn't done anything to you."
"Yes he has, he's courted you at my father's betrothal, that's the ultimate shame for my father, who's going to marry you and I lost to him in a duel."
"You shouldn't hate him, Mordred, I want you to be friends with him or at least try to. But what was I going to ask you? Oh yes, what kind a man is your Father, King of Camelot? I've heard from Morgana my High-Priestess and Morgause my sister that you've lived with him for quite a long time, back then when the Goddess's order didn't accept boys."
"So that's why I couldn't live on Avalon, then!"
"Yes, for some unknown reason, the Goddess forbade the Order to have boys, like the Christians forbade their priest to be girls."
"But their nuns are women or little girls."
"Yes. But please answer my question, how is your father like as a man?"
"He's fiercely loyal, good and kind, and also respected by his whole court. He loves his people and sees his people's suffering."
"You're only telling me about his positive side, he must have some flaws as well."
"Well, since you asked so blatantly, people say and think he's too arrogant, too proud and even boastful. But I don't think so, Gwen. Did you know some maids and some servants told me I should be King of Camelot instead of my then 'Brother'?"
"Why didn't you say yes?"
"Because then I really thought I was his adopted brother and an orphan to boot, Gwen and people said I was a bastard, which is really close to the truth." He was manipulating her into pitying him, he knew, but he needed her absolute trust to do what his aunt and mother wanted him to do, also what he wanted to do.
"Oh, you've never told me about your childhood with your father, Mordred."
"You've never really asked me, Gwen. Here comes my aunt, would you please excuse us, my Lady." He could see his Gwen was sad he called her "My Lady", but what could he do even if he loved her and were her best friend? She was a Lady to be Queen, and he merely a lowly bastard.
"She's going to be my Father's Queen." He said to himself after she left him with his aunt.
"Aunt Morgana, what do you want with me now?"
"Disguised as a bird, I've already put in her foods the potion that would make her barren. What about you?"
"I must say that was very clever of you, aunt Morgana. I'm going to wait until after her wedding to my father, to make it more painful for my father. Imagine, the paramount of shame! Discovering his new bride in love with Lancelot, his best friend and most trusted knight."
"Who told you this?"
"Why! Gwen herself."
"You should call her 'My Lady' at court now."
"Yes I know, but I can't help but think of her as my friend still."
"Some kind of friend you are, friend on the surface, but plotting against her behind her back with your aunt and mother."
"But I have no other choice, Morgana. If she weren't selected to be my Father's wife, I wouldn't, but now it's too late for that! She's already my father's betrothed."
"So you hate your Father for that?" His aunt already knew her answer, but she just wanted a confirmation from his own lips, so she could really trust him to do her task properly.
"Yes, with every fibre of my being do I hate that man. He stole my throne, and my woman!"
"Not so loud Mordred, please, others might hear you."
"Oh sorry, aunt Morgana."
"No worries. So you've chosen Sir Lancelot for this, great idea, Mordred. But how are you going to slip in his foods and drinks the other half of the love potion?"
"I'm going to be invisible when I'll do that, aunt Morgana, don't worry about this, I've planned everything so carefully and they won't know about it. Sir Lancelot is in love with Gwen already, so I don't even think there's need for the love potion?" As he said this, he didn't know he wouldn't need to be invisible to do his tasks.
"No, there is need of it because it's going to make them lust irresistibly after each other so much, that they won't be able to resist each other. I can see you're still reluctant to do this with me."
"No, auntie. I want to do this, to avenge myself from my Father, he's done enough to me for me to hate him." But he didn't know his aunt was only testing him.
"I want you to swear on the Mother Goddess."
"Fine, I swear on the Mother Goddess to do what I have to, to avenge myself against my father and to do what I must for Avalon."
He then put his hand on his chest, swearing on the Mother Goddess's honour. During the next few days before his father's wedding, and after he swore to his aunt he'd do what he had to do, Gwen came to him quite often. Although he's seen some changes in her : she was no longer the pure, innocent priestess he met in the Goddess' temple, she was now a woman filled with apprehension, and who didn't want to marry his Father. Once, when she was in his room with him alone, needing comfort from him her best friend:
"Who'd want to marry Arthur? He's prideful, boastful, arrogant! Oh Mordred, how I hate my future husband!"
"Wait Gwen, how did you escape from your hordes of Lady-in-Waitings or other noble Ladies' eyes?"
"I've disguised myself as a maid so I could come and see you, Mordred. I know you're a great Sorcerer, so I just wanted to ask…"
"What Gwen, what could you possibly want from me?"
"If you could give me a potion, to make me forget my impossible love for Sir Lancelot and my hate for my husband, so I can be a faithful Queen and Wife, and do something for Avalon during my reign as Queen of Camelot, after my marriage to your Father."
"I don't you want you to make such a sacrifice for Avalon, Gwen."
"But it's already been decided, so there's no turning back for me no more." She said fatally.
Pity for her stirred in his apparently heartless and cold heart. But as he thought he genuinely cared for her as his best friend, he realized this moment he was truly in love with her, and couldn't live without her. "I'll kill my father someday and ask for her hand in marriage when she'll be free." He thought in his mind.
"Mordred, have you heard what I said? Do you have anything for me? Your powers must be great as a Sorcerer." She was flattering his ego to get what she wanted. "Clever woman, she must have learnt trick or two from my Aunt and Mother."
"Yes, I'll make you a potion that could make you forget all troubles, Gwen, it's going to be ready in 3 days. Drink it down on your nuptial night with my father and you'll be forever faithful to my father King of Camelot." He lied to her outright about the love potion.
"Thank you Mordred." Then she hugged him close. He's never been this close to his Gwen before, on Avalon, she was only his playmate, but never did she physically hug him. And for him, it was like having the woman he loved in his arms, but could never have, since she was about to be married to his Father. However, loving the same woman as his Father's future Queen was bound to be a disaster, and Avalon's downfall. Pushing Gwen away, he said :
"Stop, others might see us, go to your room now, Gwen."
"Just a moment more." She said as she was going to hug him close again.
"No, Gwen. After you drink this potion of mine, you'll also forget about your friendship with me."
"No, I don't want to."
"But I want you to and I want you to be the greatest Queen ever in history known for her peace-bringing between 2 rivalling neighbours : Camelot and Avalon."
"You still believe in this utopic dream of yours, Mordred?"
"Yes I do. I think Camelot and Avalon can coexist peacefully together if all the prejudices against each other are resolved. But go back to your own room, Gwen, servants might find you in my company."
This time, his Gwen, no his Father's future wife finally left him alone and went to her King's chambers. "It's been a bit too easy for me, maybe my aunt or my mother's been helping me?And I lied to Gwen about the love potion. She'll hate me after she drank it down her throat and has nights of passions with her Lancelot. But then again, she won't know since she's not a Sorceress, she'll probably blame it all on her uncontrollable lust for Lancelot." Just then as he was having these thoughts, the Knight he hated the most knocked on his door and not as sober as he should be :
"Hello, Mordred, oh great Sorcerer of Avalon."
"What could you possible want from me, Sir Lancelot?"
"I want to stop loving Gwen, my friend's and my King's betrothed, but I also want to know how she feels for me."
"Just before you came, she was there too, professing her love for you, and asking me to give her a potion that'll make her forget you."
"And did you give it to her?"
"No, it'll take me 3 days to make it. And I suppose you'd want the same as well?" He asked this Knight he despised so much for his pomposity and his love for his Gwen.
"Yes, if you could Mordred, do this for me. I also came here to apologize to you, for taunting in front of everyone else at your Father's betrothal after you lost to me, I shouldn't have as a Knight."
"It's all forgotten, Sir Lancelot and from now on, we shall be best friends, loving the same woman who's forbidden to us, because she's about to be married."
"Really? Will you give me the potion to end all my troubles in heart matters?" asked the gullible Sir Lancelot. But then again, he was a master manipulator, using people's desires, dreams and aspirations or he thought so of himself, not knowing he was being manipulated himself by his aunt, Grandaunt and Mother. He thought he was working for Avalon because he loved the place like a second home to him. But the sad thing was, his aunt, mother and grandaunt planned this all along between them. If he knew, he'd be furious against them and maybe even liked his Father's better. But living on Avalon for all these years distorted his view about his Father, and because his Father had the woman he loved too, he hated his Father more and more. Plus, he also coveted the throne of Camelot, hence why he agreed with his Aunt and Mother to make his Gwen childless.
"Yes sir, I'll be making it for you and come and get it in a 3 days and you'll be drinking it during Lady Guinevere's nuptial night."
"Why?"
"Because otherwise, its' not going to be effective."
Both the Knight and his Gwen listened to him, since in 3 days, they came for their potion. "I played well on their desperation to forget their love for each other and Sir Lancelot seems to believe we're friends now."
"Do you have it, Mordred? And Lancelot, what are you doing here?"
"Yes I do, here they are in these vials and Sir Lancelot is here for the same thing as you, my Lady. Take it and drink it just before you nuptial evening, Gwen, Sir Lancelot, do the same on my Father's and Gwen's nuptial night and you shall forget each other forever." He answered for the handsome Knight.
"Thank you, your Highness."
"Your Highness?" He asked the Knight a bit non-plussed.
"You are your Father's child, aren't you? Then you are Camelot's Prince and Heir." "Yes I am." If he didn't want Camelot's throne before thinking he was his Father's adopted brother, he now knew he could very well be his Father's only heir, and he'll be forced to put him on the throne, whether he was an illegitimate child or not since by his Father, he was the Pendragons' direct and only male Heir.
"Thank you for esteeming me, Sir Lancelot, but really, I am a bastard son and I have no right to my Father's throne, my Father's sons with his Queen, the Lady Guinevere, will be Kings of Camelot. You should all go now, otherwise people will notice your absence in the festivities." He said so even if he knew his aunt dropped the potion to make his Gwen barren in her foods and drinks.
"You're right Mordred, we'll be going now."
For him, the formal festivities for his Father's and Gwen's wedding were excessively boring, even as he lived in Camelot, he detested these things. But he had to be there as his Father's child and as Gwen requested his presence especially today. And Sir Lancelot was his Father's best man.
It was too much for him as he watched his Gwen, no his Lady Guinevere's marriage to his Father. Suddenly for him, because he wasn't paying much attention to the Christian wedding the priest who officiated their union, asked :
"And who gives this Lady to the King Arthur of Camelot?"
"I King Leodegrance her father do and as a wedding gift, I'm giving the Knights of the round Table, who shall serve you my King most loyally during your reign." And he did as he said, naming the nights for his Father's round Table.
"And I her adoptive mother Morgana, do."
Immediately thereafter, his woman was taking his late grandmother's place as the Queen of Camelot. During her crowning ceremony, he noticed she couldn't take her eyes off Sir Lancelot's and the Knight his "friend's" eyes were lost in hers. "Oh great, the love potion is taking effect… though I didn't think it'd be so quick. And look, my Aunt Elaine has fallen for the handsome Lancelot too… I could use her jealousy for my Gwen later on…" But he was too busy watching his Aunt Elaine and his Gwen, now his Father's wife and Queen, to note Sir Agravaine and Sir Tristan, his maternal Grand Uncles' eyeing his father with intense hatred. If he did see it then, he'd have used them too in his diabolical plans.
