“This is weird. It’s a key with an incredibly beautiful gemstone!” Joshua whispered with excitement. “It’s pure gold too!”

“Wait a second. This is unique. There’s something written in this gemstone. A rune,” Nestor examined with fingers and scrutinized closely, “this stone is a Turquoise!”

   “What does it do anyway?” Joshua asked, “It gives an alarm! Hey, but definitely I could guarantee that this does not come from Egypt. You see it in movies. Once you touched something from the pyramids, BOOM, down the whole place collapsed. ”  

   With those words, a bolt of lightning stroked the cave, causing the cave to vibrate violently, as if a giant have shaken the entire cave. The screaming students ran out of the cave, like a herd of rhinoceroses, into the violent storm. Joshua and Nestor could not move even a muscle. It seems like the gravity of the earth have pulled their feet against the ground, preventing them to escape from the cave.

“Darn! I should have kept my mouth shut!” Joshua yelled. “The weather and gravity betrayed us! Is this our fate, or someone did that? Who the heck did that?”

“I did that,” a voice said, as the rocks froze in the air like clouds. A familiar girl appeared in front of the boys, giving them a sly grin. It was the pixie like girl who mislead the way, but now, her true identity was revealed. She was definitely a pixie.
“Heck! Gravity! Where are you! I mean yes! Gravity, freeze those rocks there! And gravity, stop pulling my feet so tightly on the ground!” Nestor complained.  

“You again? Hey let us go!” Joshua said. “Who are you?”

“I would until you listen to my words. I am Poisen, the pixie.  You boys wouldn’t want to spend a long time with a creature like me because I could just disappear with a blink of your eye. You know it well. Now, let’s get into business. For 19 years, I have finally found the two heroes which Arthepolis needs. No one has discovered the presence of this key, but only both of you.”

“So what’s your point? And what do you want?” Joshua asked.  

“We need your help in saving Arthepolis. You have to join with the Princess, the Guardian Angel, and the unknown hero. Five of you would have the power of five that could bring peace to our world. However, you have to pass into the mission of life and death.”

“Your world is called Arthur police?” Nestor frowned. “Sounds like the founder is a police called Arthur.”

“A R T H E P O L I S, Arthepolis,” Poisen spelled.

“I don’t think things like that exist. It only appears in games, novels but not in reality,” Joshua said. “We don’t know what prank you are trying to play with us again.”

“This is not a prank. Arthepolis really exists and this is the key, which would turn into a painting if you know how to. You would enter the magical world through the painting. I know that it’s hard for you to believe but never say you never believe, because every word I say is true.”
