Klaus followed Yuna out of the palace, and she led him around the back of the palace and through an uninhabited lane. They walked until they reached a remote hillside.
Yuna stopped and whispered a mantra to the thorny bushes on the hillside, which soon parted on either side to make way for them.
"Come in with me," Yuna said to Klaus.
As they entered, Klaus noticed that the cave walls were illuminated at intervals by a fluorite lamp, and water was dripping from above onto his body. He looked up and saw that the cave ceiling was covered with stalactites, from which drops of water were dripping. The further they went, the wider and wetter the passage became.
As the water gurgled in front of him, Klaus looked up to see a thirty-foot waterfall, with water flowing from the top into a naturally occurring oval pool.
A large hole had been made in the top of the cave, through which the moonlight fell upon a girl. She was sitting beside the pool with her back to them, and she couldn't help turning her head when she heard footsteps approaching.
"Aunt Yuna," the silver-haired girl called out to Yuna, and then she looked curiously at Klaus.
"Have you finished absorbing the energy of the Magic Nucleus?" Yuna asked the girl, Lilly.
"Almost," the girl replied.
That's when Klaus noticed the Gray Spider's magic core hovering in mid-air in front of the girl, who was apparently absorbing the core's energy.
"Wait, what did you just call her?" Klaus asked, then realized, "Is she the Queen of the Succubus?"
Yuna nodded and said to the Queen of the Succubus, "Keep up your work."
"But once I've absorbed the Magic Nucleus's energy, I'll still need..." The girl trailed off.
Klaus looked at Yuna suspiciously, unable to fathom what the woman was thinking.
"I said I was going to make a deal with you," Yuna said to Klaus. "I need you to help Lilly with her final evolution."
"I don't understand what you mean," Klaus said warily to Yuna.
Yuna glanced at the girl who was absorbing the energy of the Magic Nucleus, and she sighed softly. "Do you know why I want you to take the Gray Spider's Magic Nucleus as a dowry?"
"Why?" Klaus asked.
"Lilly is Queen Evelyn's only child, but she's been deformed since childhood. She's not like the other Succubus. She was born without horns, and she doesn't have wings. She was as ordinary as a human girl. Succubus typically undergo metamorphosis between 14 and 16 years of age and are usually able to forage on their own. And Lilly, on the other hand, doesn't even know what sex is. So I looked up all the books and finally found a cure for her. That is to use the Magic Nucleus of a Level 7 Warcraft to assist her in completing her transformation, and she is now one last step away."
"The last step?" Klaus asked. "Does this have anything to do with me?"
Yuna nodded. "She needs to have sex with a powerful man and absorb the essence of that person so that she can complete the transformation."
"So you're going to let me do it?" Klaus asked.
"You're the most handsome and powerful troll I've ever encountered." Yuna spoke again, "When Ruby told me everything that happened to you in the Abyssal Lands, I was convinced of your abilities."
"Your compliments don't move me." Klaus said. He was not Rand; he had not fallen into a honey trap and could not be enticed.
"If you're willing to help Lilly complete her transformation, I'll let her marry you." Yuna revealed her intentions.
"Why me and not Rand?" Klaus was skeptical.
"Because you're smarter than your brother." Yuna explained, "And I like you, too. I want you to have Lilly's virgin night."
"Then you will break your oath."
"No, I didn't break my oath." Yuna clarified, "I'll still keep my promise to marry a troll, but I want Lilly to marry you."
Klaus was silent, and Yuna continued, "If you marry Lilly, that old man Quinn will definitely make you the patriarch, and you don't want your brother to be the patriarch, do you?"
Klaus faltered, knowing that Yuna's words were meant to lure him into helping Lilly complete her transformation, but she was right.
He wanted to be the leader of the trolls.
"I do." Klaus accepted Yuna's deal.
"Good." Yuna smiled contentedly as she shifted her gaze to Lilly, who had absorbed all the energy from the magic core.
The Magic Core, which had been glowing brightly, became dull, fell from mid-air to the ground, and shattered. Lilly stood up and faced Yuna and Klaus.
"I've absorbed all the energy of the Magic Nucleus." Lilly said to Yuna, "There's one last step left."
"This is the man I've chosen for you." Yuna said to Lilly, "He's a powerful and heroic troll."
Lilly looked at Klaus. Her eyes transformed from brown to purple as she absorbed the energy of the magic nucleus, her skin glowing strangely in the moonlight. Dressed only in a light, sheer gauze dress, her petite figure loomed beneath the veil.
"Lilly, if you don't know how to please a man," Yuna said, "I can show you first."
"No, Aunt Yuna," Lilly replied, glancing at Klaus. "I can do it."
"Good," Yuna said, "The rest of the time belongs to you."
She turned away, leaving Klaus where he was.
Slowly, Lilly approached Klaus. She came close to him and sniffed him like an animal, curious about him.
"You smell different," Lilly said, looking up at Klaus with her violet eyes shining brightly.
"Do you smell other men?" Klaus asked.
"Aunt Yuna once put me in contact with other men, but none of them could arouse my sexual desire," Lilly explained. She began to undo Klaus's fur coat, her movements delicate.
"Do you know what you're doing?" Klaus asked.
"Of course I do," Lilly said as she removed Klaus's shirt.
She caressed his broad chest, then rested her head on his heart and listened to its beating. After a few seconds, she looked up at Klaus again, this time with a wistful expression in her eyes.
Klaus looked at the young Succubus before him. She was like a ripe, juicy peach, still retaining the innocence and immaturity of a virgin.
But soon she would not, for he would pluck the plump peach and let her sweet juice gush forth.
His body immediately responded physiologically, and the troll's primal desires were at that moment unbounded.
"Aunt Yuna told me that every girl's first time hurts," Lilly asked. "If I feel pain later, will you stop?"
"No, it won't," Klaus said, picking up Lilly with both hands. She immediately wrapped her bare feet around Klaus's waist.
"I'll be with you the whole time," he said.
