Lucy ran to join the offense team asking Nashi for Sagittarius' key in order to activate her star dress.

"Star dress!" said Lucy "Sagittarius form!"

Partnered with her celestial spirit, Lucy began to draw back her bow.

"Star shot!" she shouted as she fired her arrows into the sky. This drew his attention to the ground in order to prevent him from consuming any more of the star's energy.

"Alright Nashi, let's do it!" Natsu exclaimed.

"I'm all fired up now Dad!" Nashi said with Natsu's signature smile. Natsu took a hold of Nashi's hand and used his fire dragon roar to leap both of them high into the air together. The two of them landed right in the middle of his back.

"Fire dragon iron fist!" they both yelled as they slammed their flaming fists into Claudius's back, causing a huge explosion. He let out a huge roar in agony and began to shake his body aggressively. Nashi and Natsu tried their best to hang on for dear life but they were thrown high into the air in a matter of seconds. This angered him enough to power up another star beam. He took a deep breath and his scales and throat once again glowed a bright purple.

"Nashi! Natsu" cried Happy. He and Carla leaped into the sky as quickly as possible.

"I got you" said Carla as she grabbed Natsu.

"Are you two alright?" asked Happy as he took a hold of Nashi.

"We're alright thanks to you two," replied Nashi before turning her head back over to Claudius and letting out a scream in terror "watch out!"

He opened up his mouth and fired the star beam towards them in an attempt to kill both of them. Nashi knew what she had to do, and Happy did not like having to do it again. Nashi took a deep breath and quickly began to swallow the star beam to protect her dad and Carla.

"So hot!" he whined as the heat surrounded the two of them. She once again started to cough up smoke as a result.

Lucy shot another arrow towards Claudius, this one striking right into his heart in order to help protect her husband and daughter. This caused him to fly downward, towards the battlefield.

"Again!" shouted Makarov with determination.

Everyone rallied up their best attacks and fired them at Claudius with the same amount of strength as before.

It made no difference. Claudius continued to absorb what little magic still remained, gaining so much power all at once. The cultists were also starting to break through the defenses.

"I don't know if we can keep this up much longer!" cried Gray as he tried to catch his breath.

"Just once more!" shouted Makarov, determination tinged with desperation evident in his voice.

Everyone began to gather what little strength they had left. Everyone who'd defended the hordes of cultists turned their attention to Claudius for that final blow.

"Regulus Lion Brilliance" exclaimed Loke, starting then off with what he hoped would serve as a powerful flash grenade, blinding their opponent.

"Let's end this bastard!" Laxus called out, his body shimmering a deep crimson as he called upon his Red Lightning. He roared, sending a brilliant flash of immense power towards the dark dragon.

"May the seven stars bring judgment upon you" said Jellal "Grand chariot!" Erza followed with her grand chariot spell right after him. Both of them released two powerful light blasts towards him with all their might.

"Juvia," called Gray, his skin turning black as he took a stance. Juvia knew through the years of experience fighting together what he required of her, and was eager to provide it with utmost confidence in his abilities, just as he trusted her.

"Water cyclone!" shouted Juvia.

"Ice Devil's Zeroth Wave!" shouted Gray, combining his powers with Juvia's water to send a torrent of cursed ice towards their target.

"All crush!" Gildarts said he began to thrust his hand towards the sky, sending a blast of energy hurling towards Claudius.

"Grand fairy spell", said Cana "Fairy Glitter!"

"Sky dragon roar!" Wendy shouted.

"It's over Claudius!" exclaimed Lucy. "Star shot!" She fired her arrows straight towards him along with Saggitarius.

"You and your cult are never gonna hurt my family again!" Natsu yelled "Fire dragon roar!" His fire covered nearly every inch of his body in a matter of seconds.

Claudius took all of these attacks and more, and seemed to be getting weaker and weaker. It was imminent that all that magic was beginning to take a toll on his life. But that wasn't gonna stop him, his chest began to glow a very blinding purple light, he began to power up all of that stored energy at once.
Nashi saw her chance. Signaling to Happy, he nodded as he flew her as close as he could possibly dare.

"Finish him Nashi!" Happy cried out as loud as he could.

Nashi drew in a deep breath, concentrating all the ethernano she had in her and absorbed it into a massive orb of raw power inside her mouth. Her hair began to move as if it was blown by the wind, small dragon scale like markings appeared on each of her cheeks and a star marking appeared right in the middle of her forehead glowing as bright as the stars above. When she was sure she'd gathered all that she could, she fired a bright magenta colored star beam towards Claudius. Which he gladly swooped in to absorb.

But in his arrogance, or unwillingness to see his imminent defeat, he took the blast from in full, confident that a mere child and his mortal enemies, wizards couldn't possibly end him.

The power just became too much for him to handle. He knew it the moment it all hit, but could do nothing to stop it now. He couldn't deflect or dodge it, nor did he have any power left to counter its effects. In desperation he tried to disperse it, but it was too late. Claudius exploded into dust killing him instantly.

Following his death, every member of the cult stopped moving, as if frozen in time. They turned pale, then gray. The mages could see it wasn't just a change in color they were witnessing. The bodies of every single cultist were quickly disintegrating into nothing but ashes, holding their forms until the particles steadily floated away in the soft breeze.
