Chapter 3: The Sacred Sword Caliburn

"Come on guys. I'm waaaaiiitttinng." Sonic said impatiently, standing outside Misty Lake while Team RWBY finally caught up to speed-hog.

"Seriously…next time…slow down…will ya…" Ruby repeatedly gasped for air along with the other girls as neither of them, including the speedy rose Huntress herself are nowhere near Sonic's top jogging speed to keep up with him.

"Hehe, sorry." The hedgehog embarrassedly scratches his grinning head.

"Anyways, is this the Misty Lake?" Weiss says as she's looking around the area.

'Yes it is.' answered a mysterious, familiar voice in their heads.

"WOAH." The Avengers said, spooked.

"Who said that? Merlina, is that you?" Sonic asked the voice in their heads.

'Yes. it is. I'm talking to all of you through your mind with my magic.' Merlina answered with her telepathic magic.

"So, you're a psychic? Awesome! Wish I have that kind of ability. Just think of all the pranks I could do with it." Yang said, now stuck in a daydream if she had psychic powers, only to be snapped back into reality. "Sorry." She shyly scratched her long, bushy hair.

'Anyways, I advise you all to keep moving forward. Remember the fate of this kingdom rests in your hands. Do not fail us.' Merlina advised.

"You can count on us. I mean, stuff like this happens to us all the time." Sonic said as they get a move on through this misty lake.

The avenging heroes quickly stumbled upon some old waterways and ancient palaces for Sonic to practice his rusty sword-swinging skills on some wooden targets, hitting each one successfully before they on some approaching rails. They later come across some wild boars on the bridge, forcing the blue blur to guard the ones approaching him while the Huntress trainees parkour off the walls over the pig army, all while impressing Merlina who is watching them from her crystal ball at an unknown location.

"I'm impressed, Sonic," Blake complimented the hedgehog with a smile. "Your swordsmanship has improved in no time flat. Usually, it would take weeks for someone to adapt to a new weapon."

"Guess you could say I'm a fast learner," Sonic replied with a smirk. "But I do wish there was something tougher. I'm starting to fall asleep."

"Yeah, I'm getting bored breaking cardboard targets all day. Is there anything better we can beat up on?" Yang sighed.

The group then approaches an open area with broken down columns all around them. There, they hear a faint roar from the distance. "Did anyone else hear that?" Weiss asked as they stopped on the dime.

"I heard that too. It almost sounded like a dragon." Ruby responded. Just then, a giant, blue dragon lands right in front of everyone, letting out a booming roar for the entire foggy lake to hear. "IT'S A DRAGON!" The Little Rose screamed.

'Not just a dragon, but the ruler of this lake: The Mist Dragon!' Merlina explained.

"But what does it want with us? We just wanted to go through!" Weiss asked while trying too hard not to be terrified.

"Well, some of you were getting bored and wanted something tougher, so I got the Mist Dragon to help with that." Merlina answered, having all angry glares right at the two morons that were complaining for a tougher challenge.

"Heh heh. Sorry." Sonic and Yang sheepishly responded to their nasty stares, scratching their heads.

Blake sighed, not in the mood to deal with those two imbeciles while they have a dragon to slay, "Well it looks like we have to fight this thing before we can move forward." The Cat Warrior and her friends get into fighting position to fight against this scaly beast.

The team spread out and attacked the dragon's head one by one at a very fast pace, making it harder for it to react and dodge. It started to roar to push them back, but Blake and Weiss were able to notice this beforehand and dodge it. They continued their assault just as Yang comes right back up and gives it uppercut from its chin, with Sonic and Ruby then hopping on top of its head to cut off its crystal. The dragon screams in pain as it flies out of the area.

"Well Merlina, how was that? Did you like our real power?" Sonic smugingly asked the wizard.

'T-That was amazing! Defeating the Mist Dragon like it was noting. The mark of a true knight…' Merlina said, so astonished by the fact that the Avengers beaten the powerful Mist Dragon so easily.

"What can we say, it was a breeze." Yang punned, getting everyone but a laughing Sonic to groan.

"Let's just go before Yang makes another bad pun." Weiss said, heading towards their goal.

The D-Avengers finally found the place where the supposed sacred sword is resting. Sonic ditches his old sword and hops on some rocks until he is right next to the slightly rusted, but golden sacred blade.

"This must be it." Sonic muttered to himself, ready to pull it out.

Just then Merlina teleports right next to Team RWBY to watch as Sonic is ready to pull out the great sword. "Are you ready?" Merlina asked the hedgehog.

"Ready for what?" Sonic responded, confused by her question.

"If you remove that sword and take out King Arthur with it, you all shall be known as the worst of knights, the slayers of Kings." Merlina explained.

"WHAT!" Team RWBY shouted.

"Then what can we do? We don't want to look like bad guys. We're only trying to help out." Ruby asked the wizard about an alternative.

"I'm sorry, but there is no other way. You have to extinguished King Arthur's heart if we want to save this kingdom." Merlina answered, leaving a depressed Ruby to sulk.

"Ah, it's okay, Ruby. We can't be the hero all the time." Sonic grinned to cheer up Ruby, which did the trick after he sees her bright smile. With an almighty pull encompassed by a golden light, Sonic pulls the great mighty sword from its resting place and starts examining it.

"The sacred sword..." Sonic said, astonished.

"It goes by the name Caliburn." Merlina informs the hedgehog of the blade's sacred name.

"Caliburn? Sounds pretty lame compared to Ember Celica." Yang commented, while showing off her arm gauntlets.

"I wouldn't say lame. It does sound like a name that would fit for a legendary weapon." Blake told her.

"I guess so, but it does look kind of sorry looking for a legendary weapon." Sonic responded, disappointed with how old and un-cool this so-called sacred blade looks like.

"Fool!"

"Woah!" Sonic was in shock when he heard the sword start talking with a surprise male's voice, accidentally dropping it then picking it right back up to see if he wasn't hearing things.

"You are the chosen one!? You are but a squire!" The Sacred Sword Caliburn made fun of the chosen blur.

"Oh yeah!? Says you!" Sonic retorted.

"Wait, did that sword just…talk?" Weiss asks, with the other girls slowly answer the stunned heiress with a stunned nod.

"The sword has a mind of its own. It selects its bearer." Merlina explained.

"Yeah, well it's got a pretty smart mouth on it for a sword." Sonic said.

"Then you two make the perfect duo." Weiss smirked at the unamused hedgehog.

"I wished my weapon could talk. I would like to know what the Crescent Rose has on its mind sometimes." Ruby said, creepily fonding her futuristic-looking scythe.

"Hmph! The impertinent one is you, knave," Caliburn said to Sonic. "The little maiden child doesn't seem to mind my being. Anyways brace yourself, for I shall train you until you are worthy!"

As soon as he said that, a horse sound is heard from the distance, getting Sonic and the others full attention as they see who's coming for them.

"Well I hope you can train him fast, because we got incoming!" Yang and the others get their weapons out as the Dark Knight himself, King Arthur is in full view, ready to attack.

"All right professor, work your magic!" Sonic said, preparing for battle with the dark king himself.
