This particular chapter is told from Maddie's POV, hope you enjoy

I heard a huge crash farther down in the building. "What was that?" I asked David, worriedly.

"I'm not sure, but we should probably stay away from it." He told me. We had snuck out of the truck soon after Ryan had left. There were a lot of arcadia grunts running past the room we were in to go and try to find the source of the loud crashing. We waited for all of them to run through before we left. We were walking down the hall as quietly as we could, trying to find where they keep the new unwilling recruits.

We had been wandering around for about an hour when, "Who are you? What are you doing here?" A male voice asked behind us. We turned around and it was someone in the arcadia uniform.

"Uh… building inspectors?" David tried to come up with an excuse for us.
"The building was just inspected." The Arcadian responded and his duel disk extended.

"Oh, we're doing. Let me handle this. I have some improvements I wanted to test." I said eagerly before pushing David behind me and my own duel disk extended.
"What are you doing here?" The man asked us again as he drew his cards.

"Trying to find my cousin. You probably don't know where she is though." I told him sassily.

"You won't find her here." He placed a card on his duel disk. "I activate terraforming, bringing Dragon's Ravine to my hand. I activate Dragon's Ravine as a field spell. Then I use its effect to discard Dragunity Phalanx to bring Dragunity Dux to my hand. Then I banish Phalanx to special summon Garuda the Wind Spirit and normal summon Dux." The hall way around us turned into the walls of a canyon and the two winged humanoids flew down from the sky above, floating on either side of the grunt. "I will then set two cards"

"Hm. Whatever, they look weak anyway. I'll start by normal summoning White Stone of Ancients. Then, I'll discard Sage with Eyes of Blue to activate his effect." A white spherical stone emerged from the canyon's floor in front of me and the sage walked forward, tapping his staff on it. His essence went into the stone and it erupted in white light. "I target one level one light tuner on my field, and send it to the graveyard. Then, I can summon a Blue-eyes from my deck!" From the eruption of light the majestic Blue-eyes white dragon roared and showed itself. The light died down with the star of my deck now on the field. "Now, Blue-eyes, attack Dragunity Dux! White Lightning!"
"Not so fast. I activate quaking mirror force, forcing your dragon to take cover from the falling debris and making it flip face down, not resurfacing for fear of getting injured." The canyon shook and the Blue-eyes shrunk down into its card, looking scared.
"What?! Not fair!"

"Are you finished?"
"With my turn, but that means a second Blue-eyes is summoned, thanks to my White Stone being sent to the graveyard." The shards of the white stone scattered around the field started swirling into a white glowing portal and a Blue-eyes flew out of it, showing that this dragon won't be kept down.

"Garuda's effect forces him into defense position with forceful winds making him advance cautiously." The wind whipped up, making the dragon hold its wings in front of him in a defensive fashion. He drew his card and set the monster. "I set one card and end my turn."
"Not so tough, are you?" I drew my next card, but I was already smiling. I had a play on the field since the second Blue-eyes arrived. "I fuse my facedown Blue-eyes with my faceup one and fusion summon Blue-Eyes Twin Burst Dragon, not using Polymerization because of his effect!" The two dragons' bodies swirled together and soon, a dragon with two heads and glowing markings flew in their place. "Now, he's going to attack both your monsters! Go, twin lightning!" The two heads unleashed massive blasts of electricity into Garuda and Dux, destroying them both. The man's lifepoint counter displayed and lowered down to 1100. "Next, I'll banish my White Stone from my graveyard to bring one of my Blue-eyes back to my hand. Finally, I'll normal summon Master with Eyes of Blue, to add Sage back to my hand as well." The old man rose from the ground in front of me, and raised a glowing staff, the sage's staff, and a ghostly hand grabbed it before the hologram shot back to my hand. "That's it for now."

"I draw a card and activate Dragon's Ravine. I discard this card and add another Phalanx to my hand. Then I set a monster and flip summon Dux. He is going to attack your Master." The bird man sent his whip forward and lashed my monster to bits, sending the shards forward, scratching me as my life points went down to 2600.

I smiled as he said he ended his turn. "I summon Sage with Eyes of Blue. He lets me add a level one light tuner from my deck to my hand, and I choose Maiden with Eyes of Blue." The Sage rose from where the Master once stood, raising up his staff like calling to someone and a white light shot towards my hand. "Next, I activate the Master's graveyard effect. I can shuffle him into the deck and send an effect monster to the graveyard to special summon a Blue-eyes from the graveyard. And look at that, Sage is an effect monster." I said with a confident smirk. A white blast shot up under sage and the blast turned dragon shaped before the Blue-eyes showed itself once again. "Then I use the spell Burst Stream of Destruction. When I control and Blue-Eyes White Dragon, I can use this card to destroy every monster on your side of the field, at the cost of tuckering out my dragon enough to keep him from attacking." My dragon pulled its head back, taking a deep breath and launching a massive burst of thunder and lightning into Dux and his facedown. "And now that your field is clear, you get to feel every bit of this. Twin Burst, twin lightning!" The twin heads launched forward a blast of lightning into the duelist and his lifepoints went down to 0. "I win." I said, satisfied. All I needed was a few adjustments.

"So you did. You earned my secrecy. Do what you wish." He turned around and started walking away as the canyon scenery faded back to the hallway. "Though you should hurry. Everyone will be returning to their normal places soon."

David and I rushed around trying to find a new place to sneak in, like an air vent or something. Soon enough, we found ourselves stuck in a surprisingly large supply closet. "I wonder how long until everyone leaves for the night." David whispered.
