Write a fantasy story that begins in this setting.
A Dark Night
I threw my hands into the air, and light flew from my fingertips. The land shook and the tower on the island in the architecture of the land of Japan, and it was lit up to reveal its majestic beauty under the crescent moon. Looking to the left I see the lanterns light and the other members of the order appeared upon the small boats paddled by the miniature ogres. The gathering was going to commence as soon as the sun finally set across the mountain range, this was the magic hour.
I grabbed my magic wheel spun it and opened the portal to the gathering place. Most people needed to travel to the gathering place using the boats, but I was one of a very few that could use a magic item to transport me to anywhere in the world. I said, “Here is where I need to be, this is where I want to be, so let it be.”, and bam I was in the great hall at the entrance.
I stood in the great opening with the torches lit around me. It was a wonderful site with the tall ceilings with a mosaic of samurai warriors hand painted. The flames and lightning that flew from the tips of their fingers brought tears to my eyes. I could only look and admire it for a short time because there was work to do.
I moved quickly to the door and laid my hand upon knob and spoke the locking spell and the door began to glow. I wanted to keep everyone at bay, and the anticipation to build. I had a surprise for my guests. I began to whip around in a frenzy as the inside of the building began to shift. The pictures turned darker and showed the dark shifters instead of the samurais, the lights dropped low and began to flicker madly as the air moved in a swirl, and things began to glow red. Everything was prepared and I jumped to take myself to the top of the tower.
Below I could see the commotion my actions had started. The other members began to scream as the monster I had planted there mear hours ago. It was pulling the boats under and people were being sucked into the darkness. I reached my hands to the sky and the clouds moved in and a green haze dropped over the water. Then it was time for the grand finale.
I spoke into the sky and the clouds acted as my voice and I yelled “I am the leader of the dark world. It was time for you to die.”, I dropped my hands and the water began swirling into a grand whirlpool and started sucking down the boats and their occupants. The demons from the other world appeared and flew around me. I ordered them to destroy any stragglers.
The chaos lasted mere minutes and finally the whole world began to go dark. I was the all powerful and the world was mine. The fools never saw it coming.
