"My lord ?", Pika calls out knocking on Den's study , he was nervous and stuttering as they hadn't met since the last incident where he tried to kill Ruby , and it was already been a week since that.

The door opened as Pika is taken aback a few steps as Den comes out the room looking about and asks ,"Yes? ".

"Aurther send me.. ", before Pika could answer he is interrupted by Den as soon as Aurther's name name was spoken ," oh , where is Aurther ?'.

Den closes his study door as Pika replies ," he just went below , saying that he is gonna help Ruby train the soldiers !".

"Hmm , well then you can accompany me ! ", Den replies opening his study room again , revealing a huge dark rockcave like , 100 meters tall and 50 meters wide and 200 meters in length  .

"A teleportation door!! Awesome!!", Pika thinks as his eyes beaming with happiness.

"Come", Den exclaims with his grinning face . Pika enters the cave as Den closes the door behind them.

Watching with awe , as Pika notices the cave was actually hollow , and sunlight shown through the top as he exclaims ," wow  !",

Den smiles leading as Pika is filled with a unbelievable awe as he stares at the huge castle at the end of hollow cave.

Looking back at the door , he does not find it , but notices a dark cave , leading somewhere else .

"Where is this ? My lord?", Pika asks following Den as he replies ," Somewhere far away , west of Rosendale . In an inhabited small island , isolated due to its active volcanic activity ."

Following Den walking towards the castle , Den adds ," do not worry , huge eruptions don't occur here."

Saying that , a huge shadow covers Pika on the back as Den grins turning back.

Pika wonders about the shadow covering him as he hears a growl , turning back slowly  as he notices a big long white hairy body. As gooey saliva falls on his shoulder he looks up only to find a giant polar bear , with silver armor with huge sharp teeth , as blood covering it's mouth.

Raising its bulky arms to smash him, Pika stumbles in the ground ,unable to scream Pika becomes unconscious and faints on the ground.

Den snaps his fingers , as a huge iron chains appear from the ground and grabs the huge bear's arms. The bear growls raising another arms to smash Den , a series of continues chains emerges from the ground and immobilizes the bear as Den comes up to it sighing with his worried eyes ,"Again?".

He takes out a knife from his back and carves a circle in his left palm . Trying to cope with the pain , he draws an inverted triangle inside the circle as blood spills from his shaky hand.

Murmuring his spell , he conjures dark magic as black lightning appears from his left hands. Touching the immobilized polar bear with his blood , a huge blood circle appears around the bear who closes its eyes.

As the bear becomes smaller in size , it transforms into a human male as the same age as Den , with a white hair, a tatoo in his chest and dark black eyes with only a pants on , he comes into his senses as the blood circle vanishes , noticing Den , he rushes up to him kneeling down and bowing his head , he apologises ," my lord , i'm sorry that my lord had to go through this for someone as useless as me !".

", Enough , Aeron . No one is useless in my eyes !", Den replies as he rests his arms and grips his blood dripping palm.

'I failed you , i gave in to my Aest . I failed to guard the castle .. !", Aeron apologises again as he presses his eyes with guilt.

"I said enough!",Den orders turning back and continues walking towards the castle ," carry the kid. I've come to collect some old books. Moreover , you can fail as many times but as long as you don't die , you are not a failure to me!".

Aeron opens his guilt filled eyes and grabs Pika in his shoulders and follows Den.

"you're alive , thats what matters more then some cut in the palm that can be healed !", Den murmurs pushing the huge castle door , entering it , the torches light up itself in the dim hall, revealing the dusty castle hall , the chandeliers covered with white cloth , tables and chairs also covered with white sheets were the contents of the hall.

"Kid!! Hey wake up!" , Aeron tries waking up Pika as Pika opens his eyes murmuring ,"Lord Den!?".

"No , I'm not lord Den ! Hey kid ", Aeron replies smiling as Pika wakes up surprised , getting up the bed in a dim empty room he feels weird as Aeron with his half naked body smiles at him.

"Who are you!?", Pika asks looking at his white hair , noticing the tattoo on Aerons chest he interrupts Aeron who was about to introduce himself.
"That sign , your tattoo. You're a beast transformation type Aest." Pika replies staring at the circular tattoo with an "S" shaped inside the circle.

Aeron smiles introducing and apologising ," I'm Aeron , i was send here to guard the castle and train. And  umm ", he smiles scratching his head continuing ," i'm sorry for attacking you before!",

",you're that beast , the huge polar bear!?", Pika exclaims excited and continues asking , " but why did you attack us?".

"Umm , its hard to say actually...", Aeron thinks for an answer as Den enters the room with some books in his arms replying , " he has an uncontrollable Aest. A unique beast type with undeniably strength and power. He might look intimidating but..", Den pauses as he stops walking and continues ," be weary not to get into his temper. His Aest depends on his anger and feed on it. With uncontrolled anger comes uncontrolled power."

Aeron stops smiling as Pika feels the awkwardness in the room and notices the bandaged right hand of Den. Den placing the old dusty books on the table adds, "we are leaving to  Rosendale now."

Hearing this Aeron turns back surprised about to mutter a word as Den interrupts ," yes , you're coming too. If your Aest is unable to be controlled even in a peaceful place where no one can temper you , it won't matter any difference elsewhere. I will take your matter in my hands." Den replies walking out.

" do not forget the books !",Den warns  as Pika gets out the bed and Aerons getting hold of the books follows Den asking ," my lord ,what about this castle. I am supposed to guard it."

"With an uncontrolled beast in it , the castle was fine. Without anyone guarding it , it'll be fine as well , moreover your training isn't over."Den replies walking down the stairs to the sheet filled hall.

Den , Aeron and Pika walks back to the hidden teleportation door as Pika takes another good look at the wonderful scene as the evening sunlight fills the hollow cave.
