Next chapter for Fire vs. Ice. Enjoy!

It was around midnight by the time Natsu reached Lucy's (their) apartment after the party that went on in the guild. Although Mira and Makarov told him to stay in the guild infirmary, the fire mage wanted to spend the night with his blonde beauty in a place where they can be alone. After entering the apartment, Natsu laid Lucy down on the bed and slip in with her. Lucy however woke up, and smiled at the person in front of her.

"Hi there gorgeous, you had a nice dream?"

"Yes. But I'm glad I'm awake."

"Why's that?"

"Cause I want to mate with you right now." She said while gripping the trim of Natsu's vest.

"Lucy, just so you know, once we mate, we are bounded forever. You won't be able to fall in love with anyone else. So really think about this." He said with a concerned look on his face.

"Natsu, there's no one I want to be with for the rest of my life than you. When you broke the charm spell casted by Bora, I knew you and I were destined to be together. So please, make me your mate Natsu." Natsu needed to hear this from Lucy. He wanted to make sure she understood that once mated, there was no going back. Now that she knows, they can begin the mating ritual. They filled the night with screams of pleasure, their clothes scattered on the floor. By the time Natsu bit into Lucy's neck and claimed her, it was 2 in the morning. They fell asleep together, wrapped in each other's arms.

Meanwhile…

Gray was in the East Forest, letting his anger out by beating the crap out of the green Vulcan who lived there.

"DAMMIT! HOW DARE HE TAKE LUCY FROM ME!" He kept hitting the Vulcan until a shadowy figure came out of nowhere. The man's face is concealed by an ornate metallic mask that, around the mouth area, has engravings that resemble a beard and mustache. (Arlock)

"What the hell do you want?!"

"I came to offer you a chance to take revenge." The masked man said with a low voice.

"I'm listening."

"What would you say if I told that I have the power to help you take revenge on the one that did you wrong?"

"What could you do?"

"This book I have in my possession, has all the techniques of an Ice Devil Slayer. Are you interested? Because all you have to do is join the guild Avatar, and all the knowledge that can help you seek revenge is yours." Gray couldn't believe the luck he found. Some guy was offering a chance to take revenge on Natsu. And all he had to do was abandon his guild and the book is his. Normally he wouldn't do something like this, but the Ice Devil Slayer Magic was changing him. The ice mage allowed himself to be consumed by rage, jealousy, hate, and temptation.

"Fine by me." He said and allowed the masked man to remove his Fairy Tail mark and replace it with the Avatar mark.

"Good. Follow me." Gray nodded and followed his the masked man to who knows where. They disappeared into the night. No one knew that this man would turn Gray into a follower of Zeref.

One Year Later

Most of the members of the guild have been worried about the ice mage since he has been gone for a whole year. Juvia of course was worried the most but got tired of waiting and moved on. She and Lyon are engaged, Natsu and Lucy are married in dragon slayer terms but are doing the human ritual in 4 months and now have a newborn daughter, Nashi who had pink hair and chocolate brown eyes, and Makarov was preparing the guild for the war between the Avatar guild that was rumored to be declaring war on Fairy Tail and the Magic Council.

The Dragneel Family was currently residing in their home which was Natsu's old cottage that was remodeled thanks to their friends. The cottage was a two story house with 6 rooms. The house consisted of a master bedroom, the baby's room, a guest room, a study for Lucy when she wanted to write some novels, a laundry room, and a large kitchen with a dining table made for eight people. In the backyard of the house, both a pool and hot spring was added thanks to Virgo and Aquarius.

"Hey Luce."

"Yes Natsu?"

"I have something that might interest you."

"What is it?" Natsu smirked and showed her the key of the dragon, Draco. Lucy's eyes lit up in excitement.

"Natsu! How did you get this?"

"While I was at Crocus for that mission Wendy and I took, the key was part of the reward. I thought to myself that not only can you summon Draco into battle, but you can use her powers thanks to that Star Dress magic you learn." Before Lucy became pregnant with Natsu's child, she was able to learn the Star Dress Celestial Magic Spell that allowed her to donned a dress depending on the spirit she summoned. Now that she has the most powerful silver key, she can now use Celestial Dragon Slayer Magic.

"Natsu, thank you."

"Anything for my wife." He gave her a quick peck on the lips. She smiled and summoned Draco to her side.

"Open! Gate of the Dragon! Draco!" Out of smoke, a humanoid dragon with green scales, a katana, dragon features such as a tail, claws, and scales, appeared.

"Nice to meet you master. Would you like to make a contract with me?"

"Yes I do. But don't call me master. Call me Lucy."

"Very well. You may summon me anytime you wish. Also, are you the same Lucy who can use the Star Dress magic?"

"Yes! How did you know?" Lucy asked.

"It's been going around the Celestial World that a mage with golden hair can use the most powerful Celestial spell. It's an honor to meet you." Draco said while bowing.

"Oh uh thank you."

"Well then, our contract is official. I look forward to fighting alongside you." Draco said while smiling and went back to the Celestial world. That was when Nashi woke up and started crying. Natsu rock her back and forth to calm her down.

"It's okay Nashi. Don't cry." Lucy could only smile. She couldn't believe that Natsu, a hot headed pyro, could be so gentle. Nashi finally calmed down and opened her eyes. That was when the two parents were surprised to what happen next. Nashi was laughing for the first time. It was music to Natsu and Lucy's ears. She stopped after awhile and quickly fell asleep.

"She has your laugh Luce." Lucy smiled and her husband handed their baby girl to her. She held Nashi closer to her, Nashi's pink hair tickling her cheek. After Natsu slipped into bed Lucy placed their daughter between them and fell asleep. Natsu wrapped part of his scarf around his wife's neck and soon followed her to the world of dreams.

Meanwhile in an abandoned church located deep within the Mikage Forest…

"So, are you ready?" Arlock asked.

"Yes. I will take what is rightfully mine." Gray says with a devious look on his face. In the one year he was gone, his appearance has changed. Hisback, the has swept black hair, he now has a demonic black arm, he wore a white robe that said Ice Devil on the back (written in kanji), and the most notable thing is that he had Avatar's mark on his chest.

"Once our forces are assembled, I will let you know when you can attack your former guild. Or rather the one called Salamander."

"Fine. Just don't keep me waiting. I want that bastard flame brain dead at my feet for taking Lucy from me." He said and walked to his room, thinking about the many different ways he would take revenge on Natsu.

If Gray seems too OOC, I based his new personality off when he infiltrated Avatar in the manga but more evil like and a little bit of the original Vergil from Devil May Cry. Hope you enjoyed this chapter. I will do better to make the chapters longer and update it. Until then!
