==Chapter 1: The Demon Raised Again==
My name is Alex, I am the dimensional Traveler from earth, I have been fighting the evil of the Shadow King ever since I was thirteen. He has made his final plan, to destroy each world and claim their ruins. I swore an oath to protect them all. While eavesdropping on his plans, I found out he was to go after the Mushroom Kingdom, the home to Mario and Dimensional Traveler Vivian, a once evil Shadow Siren who turned on her own Mother, the Shadow Queen.
I was at the base of the DTs, called the Gateway to Everything, preparing my trip to the Mushroom Kingdom, I filled my pack with food and water, and placed my Dimensional Sword in its sheath. I stood in front of the large arch, standing on a large circle divided into twelve parts, each representing one of the worlds. I pressed my foot onto the peice with the mushroom on it and went through the arch.
