At Knightonia.

Somewhere within the capital is Lavaria herself who is there to give one of the Nexo Knights a letter.

Lavaria: "Mm too easy" she thought and successfully done her task.

However before she could leave she saw a poster on a wall which have a castle in the background.

A few hours later.

Returning to the Lava lands Lavaria enter the training yard where she see Monstrox using his new magic like levitating a whole statue into the air.

Lavaria: "Monstrox I think you should see this" she said catching his attention thus causing him to lose focus and destroying the statue.

Monstrox: "Dang it. Reparo!" He said using his magic to repair the statue instantly.

Once fixed Monstrox look at the poster Lavaria have grabbed and he immediately recognize the castle in the background.

Jestro: "Oh I see you got the poster for the reimagine version of the Golden Castle" he said walking up to Monstrox.

Monstrox: "... We're gonna go and make sure that reimagine doesn't get finished as it's an insult to the original!" He said with a p*ssed tone.

Jestro: "Woah I didn't know you were a fan" he said.

Monstrox: "I'm not! My grandma used to tell me the stories when she was there and I won't let those Union ssholes ruin my grandma stories" he said angrily.

Lavaria: "There's also apparently an old golden stone statue that they gonna use in the background" she said showing Monstrox the photo of the statue.

Monstrox: "That's no normal statue! That's a Kulve Taroth trap in Stone!" He said confusing Lavaria and Jestro.

Both: "A what?" They both ask.

Monstrox: "It an elder dragon!" He said shocking the two.

Jestro: "If we free that dragon would it join us?" He ask a bit afraid.

Monstrox: "Oh absolutely as I was taught in old dragon tongue by my grandfather" he said.

Lavaria: "Wait what do we do about the Nexo Knight we're trying to turn to our side?" She ask.

Monstrox: "... We split up. I'll go to the Golden Castle while Roodaka will talk to the Nexo Knight and convince them to join us" he said.

Jestro: "It sound good but wouldn't all of them be busy fighting you?" He ask.

Monstrox: "Oh I'm pretty sure that Nexo Knight wouldn't be there" he said smiling.

At the Fortrex.

Macy: "No! I won't be apart of your movie Lance! And that final!" She said leaving the training room and enter her bedroom then lock the door.

She walk to her bed and lay on it then begin to cry as she remembers her conversation with her father about her future.

Flashback:

King Halbert: "Dear meet Prince Vince. Your future husband" he said introducing the prince who look at Macy with lust.

Macy: "What! Why!" She ask and disgusted by how the prince is looking at her.

King Halbert: "Well Ozpin and Sirzech had good points in Knighton needed strong relationship with other kingdoms. And what better way then marring you to the prince of Ashlar. Our neighbor kingdom" he said.

Macy: "You listen to those two! And look at him! He look like he barely lifted a sword!" She said.

Vince: "I actually use a dagger sweetheart" he said pointing to his dagger that is on the desk besides her.

Macy: "Tsk I won't marry you!" She said then was about to leave when Vince grab her hand.

Vince: "I'm afraid that not possible as it was an arrangement between our two fathers" he said shocking her.

King Halbert: "It true honey plus the Ashlar kingdom can help us as they have the Golden sword. The only weapon capable of slaying Mallock grandson plus they do have real knights and defenses" he said.

Macy: "My answer is still no!" She said slapping Vince in the face shocking her father while Vince let go thus allowing her to leave.

King Halbert: "Maybe a few days will calm her down and once Monstrox is defeated then she see there's no need for her to be a knight and be Knighton princess" he said.

Vince: "Stress will cloud the mind also don't worry as my father is sending the best knights and defenses to increase this kingdom" he said.

What the two not realize is that Macy heard what they say and cry as she realizes that she can't escape the marriage arrangements.

Flashback end.

As Macy cry to herself she notice something that caught her attention.

At the filming area.

Currently the Nexo Knights, except Macy, and Union students are acting for the Golden Castle remake movie with the old golden statue in the background.

However the sky turn dark surprising both the filming crew and the Nexo Knights.

Jurgen: "Strange there wasn't supposed to be any rain today" he said then a flash of lightning blind everyone for a second.

Once their sight return the filming crew all scream and run away as Monstrox himself is standing in the center of the filming set.

Monstrox: "So this supposed to be the Golden Castle? Pft pathetic! Fiendfyre!" He said then his staff produce a fire blast that take the form of a dragon at the fake Golden Castle which vaporize the fake into nothing.

This shock both Nexo Knights and Union students as they never hear or seen magic like that.

Clay: "Monstrox! Your path of evil ends here!" He said then dash at Monstrox but he created a barrier that block and shatter the prop sword.

Monstrox: "Next time use a real sword Clay" he said then summon lava monsters and grimms that cause chaos throughout the filming set.

Aaron: "I'll get the armor and weapons!" He said running off.

Axl: "Grr evil wizard get crush!" He said running at Monstrox but the wizard just chuckle and summon a cotten candy monster.

Issei: "Did Monstrox just summon a cotten candy monster?" He ask Rias who nod dumbly.

Axl: "Candy!" He said then chase after the monster who is quick for being candy.

Monstrox: "Heh I'm so glad I see that movie to create this monster" he thought then walk up to the old golden statue as his monsters and grimms keep both Nexo Knights and Union students busy.

It wasn't long until the Nexo Knights got their armor and weapons including a new upgrade which Merlok use Nexo Power on.

Watching all this Monstrox is a little impressed with the new upgrade but he then use blue lightning to set the Kulve Taroth free.

Merlok: "Great Goodness! A Kulve Taroth!" He said.

Ddraig: "How in the world is a Elder Dragon here!" He said.

Clay/Issei: "what?" Both ask only for Monstrox to speak in old dragon tongue.

An: due to how ancient this language is I'll write it as normal to you readers.

Monstrox: "Oh great Elder Dragon Kulve Taroth. I am Monstrox the one who free you from your stone prison. Join me and we'll get you justice against those that imprisoned you" he said.

To both Nexo Knights and Union students shock the dragon nod then bow for Monstrox who got on it back.

An: back to normal language everyone.

Monstrox: "You may had won this battle Nexo Knights and Union brats but you have lost without knowing it!" He said then the dragon fly into the air and leave the shocked heroes behind.

With Macy.

Currently she had arrived at the Waterton and enter a restaurant where she wait at a booth.

???: "Ah so you finally arrived" a female voice spoke which Macy look to see a female she never met before.

Macy;: "Um who are you?" She ask.

Roodaka: "I'm Roodaka and you princess want to escape the life of a princess" she said.

Macy: "And how can you help me?" She ask.

Roodaka: "Why by joining Monstrox" she said smiling as she see the shock in Macy eyes.

Macy: "Why would I join his side! He's causing destruction to the kingdom!" She said then notice that the people ain't running away.

Roodaka: "A little illusion to make sure we're not interrupted" she said surprising her then Macy think and relax a bit.

Macy: "Alright I'll bite and listen to you" she said.

Roodaka: "Not everything is as they seem to be and as you're aware Union cause nothing but pain and suffering for everyone" she said.

Macy: "True but Monstrox way isn't the answer!" She said.

Roodaka: "Well let's me ask you this. When have any civilians got hurt by Monstrox or his armies? And truly think about it" she said.

Macy was about to reply then think about everything so far. Truth be told civilians weren't harm by Monstrox monsters or magic. Maybe affected sure but no true harm were cause and the only thing the monsters done were destroy. Same with the grimms he created as they never harm anyone.

Macy: "Okay so property was destroyed and no civilians was harm but that doesn't excuse him from attacking" she said.

Roodaka: "True but haven't you notice how strange it is that many of these towns doesn't have defenses like walls to keep them safe from the increase powerful monsters twenty years ago" she said.

Macy: "Now that you mentioned it yeah but what that got to do with Monstrox attacks?" she said.

Roodaka: "I can't say more but if you join then you'll be free from being the princess you're father and others wanted you to be" she said.

An: pretty much what happened.

Macy: "Alright I'll join" she said.

Roodaka: "Good and soon you'll be free Macy" she said.
