"Damn, this place gives me the creeps." Kai muttered as he glanced at the palace of the spirit of dark whose name was Sierra.

Even though Kai was thinking of it as a palace, it was more of a castle. It looked like something that came straight out of an old horror book.

The castle was made from plain gray bricks and he could see that moss had gathered at the bricks at the bottom of the palace. Cobwebs also covered many areas of the castle but one thing that stood out the most was the huge black wolf sitting at the entrance of the castle.

Its fur was pure black and was golden in some places. Its ears were straight up in attention even though its eyes were closed and looked as though it was sleeping.

But Kai knew that it wasn't sleeping but was instead keeping guard.

"What's the point of keeping guard when the person you are guarding is invincible?" Kai wondered out loud as he thought about how he would get inside the castle.

'Judging from my talk with the last elemental ruler, I just hope that this elemental ruler doesn't throw me out of her palace." Kai thought as he gently landed on the ground near the castle.

He had been observing the castle from the above to see how good its defenses were ad he was now certain that its defenses weren't that good.

But that wolf sitting at the entrance was enough of a defense. He glanced at the huge castle from below before slowly going near the walls as he decided to directly teleport inside regardless of anything that will. Happen.

But before he could teleport, he heard heavy footsteps behind him as he quickly turned around to see the wolf glaring at him.

'Looks like it smelled my aura.' Kai thought with a sigh as the invisibility formation around him wore off.

"Now the question is, how powerful are you?" Kai muttered to himself as the wolf suddenly changed shapes and turned into a woman. The transformation was so sudden and smooth that Kai was left stunned. The woman had long waist-length black hair with sharp black eyes that were gleaming like diamonds in the night.

Her eyes were currently examining Kai with an interested expression as he took a sharp intake of breath. The woman standing in front of him was the spirit of dark.

"I had been wondering who you were for quite some while but now I remember who you are. You are Kai, the person who freed the elemental rulers of death and life. Now I am wondering what you are doing here?" The woman asked with a smile as Kai gulped down nervously.magic

'Now that I have met her, what should I say?' Kai wondered silently since he had no idea how he should begin the talk.

"Um, I am here on the elemental spirit of fire's behalf." He decided to say as the woman looked surprised.

"You are here on her behalf. Does she have some work with me?" The woman asked as Kai nodded.

"Yes, she has some work with you." He replied as she sighed and gestured for Kai to follow her.

"Damn kid could have come here herself. It's not like I am not allowing her from coming here. Heck, none of them come here." The woman grumbled to herself as Kai wondered whether he should be listening to this or not.

"Um, what do you mean by none of them?" Kai decided to ask since staying silent was becoming awkward for him.

"Sierra, my name is Sierra and by none of them, I mean my fellow elemental rulers." She replied as Kai nodded and kept following her.

They walked inside the halls of the castle which were strangely deserted."Only I live inside this place. There are only a total of five spirits of dark, excluding me. Those guys wander the realms and I am left alone here." Sierra said as she saw Kai's confused look.

"I thought that the number of spirits here was equal to the number of spirits on the other special realm." Kai said with a shocked expression as Sierra suddenly stopped walking and glanced back at Kai.

"Honestly, I wish that was the case." She replied and continued walking as Kai started wondering whether Sierra was a very lonely woman.

After all, if no one lived here, she spent most of her time alone and the other elemental rules also didn't come to visit her.

"Where are we going?" Kai decided to ask since they had been walking for quite a few seconds.

"We are going to my torture room." Sierra replied as Kai suddenly froze in his spot.

"What did you say?" Kai asked again as he felt as though he had heard something wrong.

"I said that we are going to my torture room. Why do you think that nobody lives here and the ones that used to live here left this place? It's because I captured and tortured everyone." Sierra replied as she turned around and her eyes were glowing brightly.

Kai's expression turned into one that of horror as chills were running against his back. But Sierra suddenly started laughing.

"I was joking! Why do you look so terrified as though I am really a torturer?!" Sierra asked while laughing as Kai blinked in confusion.

"That was not funny. For a moment I was wondering whether I should teleport out of here while I still could!" Kai replied back as Sierra kept laughing.

She stopped after a few seconds and wiped a tear off her right eyelashes.

"Damn, I missed having someone to talk with. As for your question from earlier, we are going to my throne room." Sierra said as Kai sighed and both of them kept walking.

"Don't you dare joke like that again." Kai added as Sierra giggled at his words and the two of them disappeared.

Little did he know that this moment was the starting point of a beautiful friendship.
