A/N: To answer the question of a pm about the last chapter, The Thunder-Fire Dragon does not have an ultimate attack so I created one. (Natsu x OC). Part of this chapter is from Erza's mind, Third person, but following what Erza thinks and feels. Also now I have hit enter twice, as suggested in a PM to make it easier to read

'Will Natsu be alright?' Erza asked the master. Natsu lay recovering in the guild's infirmary. He was beaten and bruised, unconscious.

On the trip home Natsu woke up in a full blown rage and had used a Fire Dragon's Roar. Gray didn't expect it, but took the whole attack meaning no one else was hurt. Gray also lay in the infirmary.

Erza had beaten Natsu senseless. Lucy and Erza had carried the two injured males into the infirmary. Some of the guild members said . 'Those two go too far…'

The thing with Natsu had never happened before. He had never lost control of himself like that. Leaving Erza to think that something was wrong. She puzzled over it.

'I'm sure that punk will be fine.' Makarov said, interrupting Erza from her thoughts. 'After all he is a Fairy Tail wizard' Makarov grinned at Erza 'How did the mission go?'

'We defeated the dark guild Nightfall including their top five strongest wizards and their guild master.' Erza replied. 'Strong eh,' Makarov chuckled. 'What type of magic did these "strong" members have?'

'Metamorphosis, Plant, Wind, Cancellation, Dark Fire, and Manipulation.' Erza replied. The master spat out his mouthful of drink. 'Ancient Spell's.' He mumbled

Romeo, Macao's thirteen year old son, ran up to Erza. 'Did Natsu fight the fire wizard?' Erza smiled. 'Sure did. He ate her fire as well.' 'Yeah big bro can't be beat.'

Erza nodded thinking back. She was close enough to hear what the Dark wizard had said. "That her magic was poisonous like Etherion. Then how come Natsu wasn't feeling the effects? Then he was acting different afterwards. There's something bigger here." She thought to herself

'Master, tell me about those Ancient Spells!' Erza demanded. Everyone nearby listened in as well. Romeo,Macao and Wakaba, at one table. Laxus and the Raijin tribe at another. Elf, Lisanna, Cana, Juvia, Gajeel and Levy were at a third table, and Mirajane stood at the bar.

'Well… First, Dark Flame is a magic that burns everything including souls. If Natsu ate that magic he should be poisoned like when he ate Etherion.' Makarov explained.

'Second, Manipulation magic allows the user to manipulate whatever he wants. Therefore he can turn magic back on the user, and change how they think. The most powerful manipulation wizards can even manipulate space and time.' Makarov said.

"So that's it" Erza thought. "Natsu's was hit by the manipulation attack. It must have caused him to change." 'Erza I want a full report in my office, now.' Makarov said.

The guild members were talking about that manipulation magic, well except Romeo who kept telling his dad he was going to learn Dark Flame magic.

Erza followed Makarov into the office. 'Erza I can see on your face that you are thinking something over, tell me what it is so I may help you.' Makarov said.

'Natsu, when he fought the guild master he used an attack on him. It was called "Emotion Manipulation" I don't know what it meant but I think it changed Natsu.' Erza stopped seeing the look on Makarov's face. 'What is it, Master?' Erza questioned.

'Em-Em-Emotion Manip-p-pulation?' He stammered questioningly. 'Yes. What does it mean?' 'It means we could be in really big trouble.' The master said. 'Natsu has been affected his mindset has changed, he will no longer be a friend of Fairy Tail, emotion manipulation makes people feel no feelings, no joy, sadness, or even anger. They just act.' Makarov explained

'So as long as he's unconscious he's safe?' Erza asked. 'For now, yes.' Makarov sighed. 'I guess, I should go see the magic council, and ask to see the Nightfall guild master, he needs to lift the spell. No other magic can cancel it and it doesn't fade over time. Erza make sure Natsu doesn't leave nor do anything stupid.'

'He will not have a moment's peace master.' Erza replied. The master grabbed his things and said 'I will be back within a day.' Then he left. Erza left the office, the master using a teleportation lacrima. She went to the counter.

'What's wrong Erza?' Mirajane questioned. 'Natsu has been affected by a spell that only the caster can reverse.' 'Oh no, poor Natsu.' 'And we have to keep him here.' Erza said. 'Well that won't be hard when he's beaten up badly.' Mirajane said, just as an explosion erupted from the Infirmary.

'Requip Heaven's Wheel' Erza said rushing into the infirmary. She saw that there was a hole in the wall leading to the outside. Porlyusica was on the ground. 'Porlyusica, are you alright?' Erza asked. 'Yes, Natsu didn't hurt me or anyone else, he just said "I'm coming." Went for the door, then turned and went out the wall.

'He probably smelt me and knew I would stop him.' Erza said. 'We must go after him at once, oh Gray is still injured.' Erza frowned. Wendy raced in just arriving back from her job. She pushed past Mirajane to see Gray injured and the hole in the wall.

'I seen the explosion and thought someone was hurt.' Wendy said. She rushed over to Gray and began to heal him. Erza turned and walked back out into the guild hall. 'Natsu has gone insane, I need a team to go with me, find him, beat him down, and drag him back. Who volunteer's?'

Gray stepped forward from behind Erza, only slightly wounded. 'I will.' Lucy agreed. Wendy spoke up 'You might need me.' Erza nodded. Gajeel looked like he wanted to go, so did Romeo. 'Gajeel, would you like to come and maybe fight Natsu?' Gajeel nodded, promised Levy he would return then stepped to join the quatro.

'Macao, with your permission, I will take your son?' She asked. Romeo looked to his father. Macao knew what this quest would mean to him. 'Only if he returns unharmed.' Macao agreed. 'You have my word.' Erza said. Happy, Carla and Lily were going to go as well.

'Laxus, Mirajane, Elfman, take care of the guild for us and send word to the old man.' Erza commanded. The six wizards took their leave. They began to follow the trail of destruction and burning fire, 'He definitely came this way' Gray muttered

Erza had led the way through Magnolia to the train station. Citizens were terrified, left, right and center. Some mumbled 'Fire.' Part of the train station was destroyed and there were some army soldier's beaten on the ground. 'Natsu. Willingly boarding a train.'

Erza made them get on the next train. They asked where the fire wizard had gotten off. Their reply was Hargeon. So when they arrived at Hargeon the trail was again easy to follow. This time an even larger party of soldiers lay beaten on the ground. 'It was Natsu the Salamander.' The group heard from the frightened citizens.

Natsu had gone down to the dock and taken a ship. Forced the sailor to take him where he wanted to go. Erza commanded the captain of a ship to follow where the other was going. At knifepoint I may add.

The group ended up in yet another town. It was called Cedar. It was a beautiful place, except for where there was a path of destruction. 'He's making it easy for us to follow him.' Gajeel said.

The group made their way up the path and ran into none other than Doranbolt of the Magic Council. 'Erza. Fairy Tail. Do you know what Natsu is doing?' He demanded. 'Nope, but we are going to stop him.' Erza replied. 'Unfortunately this is council business, he has already caused millions of jewels of damage.' Doranbolt replied

'But this is also Fairy Tail business, so we shall continue.' Erza said 'Man you Fairies are so annoying, a pain in the rear end.' Doranbolt said 'If you continue I shall have to see you are all arrested.' Doranbolt said. 'Then you'll be making an enemy of the entire Fairy Tail guild. I suggest you don't do that.' Erza replied coldly.

'Would you really risk the chance of having Fairy Tail closed down and war between yourselves and the magic council?' 'If that is what it takes to stop Natsu from doing something terrible, then yes.' Erza replied.

A man ran up to Doranbolt, 'Sir he just broke into the Demon Horn guild.' 'Good job, assemble the men at once and prepare to storm the guild.' Doranbolt ordered. 'I am sorry, I have council business to attend to.' Doranbolt said before disappearing.

Erza began to run towards the Demon Horn guild building. 'They are a dark guild, so Natsu must be targeting dark guilds' Erza established. 'Let's get there before he can escape.' Gray added.

They arrived at the guild to find it half destroyed and the half the wizards down. 'It's more of those Fairy Tail wizards' one of the remaining members yelled. 'Ice Make Sword.' Gray called stabbing the guy first. 'Where is Natsu.' Erza asked. No-one answered

'I said. Where is Natsu!' she yelled, some of the members freaked, 'He ran off once the g=master told him what he wanted to know.' 'What did he want to know?' 'The location of Zeref.' came the reply.

The members of Fairy Tail disappeared before the council member's showed up. Well after Erza learned the location. 'Our next stop is Shirotsume Town.' Erza said. 'I didn't think that guild would be there.' Gray added. 'Grimoire Heart.' Erza said thoughtfully

Time Skip 1 day

The group of six had now arrived at Shirotsume station. 'We must find Natsu before it is too late.' Erza said. If he is looking for Zeref then something must be wrong.' Erza was worrying.

As they passed through the town they noticed the lack of destruction but also the lack of chatter. Then they ran into someone. 'F-f-fairy Tail.' He stammered afraid. 'I thought it was just one of you.' Erza picked him up 'Where is Natsu?' before the man could reply she punched him knocking him out.

Another two wizards appeared around the corner. 'Farnair.' They called then caught sight of him. In Erza's arms. 'Fairy Tail.' Lucy recognized their guild mark. 'That's the Dark Guild, Midnight Hunters.' She said. 'Where is Natsu?' Erza questioned them.

'The second guy told her. 'We don't know where he is but we are looking for him.' 'Why?' 'Our master wants to recruit him into our guild.' 'Natsu may be stupid, and not right in the head at the moment but he will never join a dark guild.' Gray said.

'We must move faster, if the council and a dark guild are after Natsu, he may be caught.' Erza said, the rest of the group following her as she headed out of town, towards where what was left of Grimoire Heart lay in hiding.

A/N: Hey guys I'm sorry to leave the chapter here, but I've already hit 1,800 words, but if you please read on, It's a snip it from what happens at the guild.

Mirajane sighed, the guild sure was quiet. Erza had left her and Laxus in charge so, Laxus took everyone in the guild and set them up with patrol's and keeping watch. Fairy Tail was not going to be caught by surprise.

Mirajane knew Erza meant just keep an eye on the guild. But something didn't feel right. Team Natsu had returned from a mission with a different personality. Now Mirajane sensed something bigger. 'Warren, what's the report?' Laxus asked.

'Still nothing Laxus… Wait! Bisca and Alzack have spotted a group of wizards converging on this location from the East. Jet and Droy have confirmed another from the West. Elfman and Lisanna have spotted another to the south. The Raijin tribe have defeated all the enemies to the North.' Warren said relaying the messages.

'Tell them to get back here!' Laxus commanded. 'It sure is quiet around here.' Mavis said appearing next to Laxus. 'First master!' He exclaimed. 'We are under attack, Warren do we know the guild these wizards are from.' 'Raijin tribe has confirmed that they appear to be led by Midnight Hunters, but there are several dark guilds.'

'Well I hope you are all prepared to fight for Fairy Tail?' Mavis asked. 'Alright Fairies!' Laxus's voice boomed 'We have an enemy the dark wizards, someone must have sent a contract out on us. Prepare yourselves this is going to be a long fight.' Laxus said. When the Raijin Tribe, Elf and Lisanna, Alzack and Bisca, and Jet and Droy arrived into the guild they were not alone.

'Mermaid Heel! Saber Tooth! Blue Pegasus! Lamia Scale!' Laxus exclaimed 'I thank you all for coming.' Sting, Rogue, Olga, Rufus, and Minerva had arrived from Saber Tooth. Jura, Lyon, Chelia, Yuka, and Toby from Lamia Scale.

Kagura, Beth, Miliana, Arana and Risley from Mermaid Heel. And Ichiya, Hibiki, Eve, Ren and Jenny from Blue Pegasus. 'Mirajane!' Jenny called happily 'Jenny!' Mirajane called back. The two embraced. 'I hope you can throw all your power out. We need a win.' Mira said. 'Don't worry, this is what you do for friends, right?' Jenny replied.

All of Saber Tooth, Mermaid Heel, Blue Pegasus, Lamia Scale and Fairy Tail grinned at each other knowing just how likely they were going to win. 'Oh no.' Mavis said. 'What is it First master?' Laxus asked. 'It's him, I wouldn't expect him to be here. Why?' The master seemed to be talking to herself. 'But I have a strategy.' She smiled proudly as the rest of the wizards cheered.

A/N sorry about the long second part but between the guild, Natsu, the group rescuing Natsu, and Makarov, there is a lot of stuff to put in. The word count at this point is 2,361
