After they heard what Kent said, they were astonished. Their minds went blank.

"What do you mean by Joker?" Klaus asked cluelessly. Then Mack explained,

"Ace and King-level sanctuaries can mask their aura and make us believe it is a lower-rank sanctuary. They are known as Joker."

"The sanctuary we're in is an Ace rank. The aura is just too strong." Althea said.

"I don't believe it. How can an Ace-level sanctuary be able to cover this tremendous aura?" Kent said, concerned.

They tried to leave using a teleportation stone, but all the gems they had weren't working. Althea began thinking of their next moves.  Then June realized Klaus was nowhere to be found.

"Where did he go!? Reyes, can you track where he went?" Althea said, worried as his death would be due to her carelessness.

"Already on it, I found his footprints. If we hurry, we can still catch him."

They followed the footprints, and soon they found Klaus standing in front of a cave. Mack called out to Klaus, but he ignored him and went into the cave. They ran after Klaus to stop him, but they found him standing frozen stiff with fear.

"Klaus, what is wrong with you? Why did you run away like that?" Althea yelled at him, while the others were petrified with the sight they saw. Then Kent whispered.

"Uh...Althea, look up."

Althea looked up and saw an enormous dragon with black scales, an orange underbelly, and torn-up wings glaring at them. They stood still looking at the dragon, but Klaus, being the simple-minded person he is, yelled at the top of his voice and started running.

This provoked the dragon. A blast of fire was hurled at them. Kent quickly stepped up and blocked the attack with his shield.

"This dragon sure does pack a punch. Even my shield could barely hold its power."

"We need to stick together to defeat it. There is no other option. Reyes, I want you and June to support us. Kent, protect Reyes and June, while Mack and I will attack it. Everyone got that?"

"Yea!" Everyone replied. They used every move and spell in the book to try and finish off the Alpha. No matter what they did, they were the only ones who were getting tired.

"Althea! This isn't working. We have been fighting him for about 30 minutes and still haven't been able to put a scratch on his body." Mack yelled. The dragon got ready to use its move again, then June noticed something.

Kent blocked its attack again. This time his shield was on the verge of crumbling to pieces.

"Althea! There is a blue flame on its back. That's probably its weak spot. It is left wide open when it gets ready to use its fire attack. You can use this opening and attack it." June said.

"Go on, do it, Althea. The next time it uses that overpowered move. I will stop it while creating an opening for you." Kent said, assuring them that he would be fine.

"Fine then, let's try that." Althea agreed.
