Summoning America version 1 has been discontinued. I may produce a completely new story but with the same title, some time in the future. in the meantime, please check out my other works on RoyalRoad by googling "Manifest Fantasy" or "Arcane Exfil" -- -- Entirely cut off from Earth, the United States finds itself in a scientific impossibility: the entire country, including the continental landmass and separated states and territories, was transported to another world. Unlike Earth, this new planet boasts phenomena unknown to science. Magic reigns supreme in this new region of the universe, bolstered by the natives' own scientific progression. Monsters roam wastelands and dungeons, subsisting off unfortunate travelers, local fauna, and sometimes even entire towns! Ambassador Samuel Anders is tasked with contacting the various nations and entities of this new world. Despite his best attempts at diplomacy, the arrogance and hostility of the natives prove to be an unnavigable barrier. War is the only alternative. Eventually, fears surface regarding an ancient evil: the Ravernal Empire. How will the United States handle the threats of this new neighborhood? What magical wonders will its adventurous citizens find? This Summoning Japan (Nihonkoku Shoukan) inspired work will follow the United States as it is summoned to a Elysia. TARGET AUDIENCE: If you enjoy GATE or are otherwise interested in seeing how modern armies and technologies interact with less advanced societies, you'll enjoy this story. This story also features quality grammar and writing, with minimal typos and errors.

Game X-Over and Marvel Crossover Call Of Duty IW/AW and Halo S.A.T.O 7th Fleet was sent to investigate an unknown Forerunner planet to discover the energy readings on the planet. Captain Thomas Lasky from S.A.T.O sent a recon team comprised of Spartans (II, III), Sentinel Task Force and S.C.A.R team to locate the unknown artifact. When the team retrieved the artifact they bring it to the Infinity, when the artifact activated an unknown slipspace began dragging the fleet to an unknown universe that sents them to the Marvel Universe. Note: I do not own Marvel, Halo, and Call Of Duty IW/AW. In this world, S.A.T.O (Solar Alliance Treaty Organization) is a formal alliance between the U.N.S.C and U.N.S.A. There primary focus is to defend Earth and all colonies from threats outside their world. I will also be using elements from Splinter Cell and Metal Gear.

(The art belongs to their original owner! Azur Lane and SCP did not belong to me) Note #1: I Will Keep The Cussing To A Minimum Unless It Was From The SCP File Itself Note #2: If You Don't Like The Book, Don't Force Yourself To Read It. I got rank 1 at shenanigans, somehow lol - 11/12/2021 I got rank 3 at scpfoundation, somehow - 13/12/2021 Everything is fine for Azur Lane, they have beaten the Sirens, the Eagle Union, Royal Navy, Sakura Empire, Ironblood and other factions have been reunited. It was at a stormy night, the shipgirls decide to start a party at the cafetaria, but then the lights were out. Everyone were in a panic state, and the next thing they knew, they were on a theatre. And an unknown entity told them that it was the entity that bring them here, and it said that they were going to react to the secret of their Commander, Dave, who were known as Dr. Kondraki.
