This story takes place in a fantasy world where demons, humans, and faunus (humans with animal qualities) fight for survival. A world where the rifle is shunned in favour for the sword and sheild. The Visean kingdom has recently defeated the Demon Queendom in a war and has secured a large amount of territory and also allowing other kingdoms to form such as the Empire of Japan with its famous samurai and the Spartan Kingdom with its legendary Spartan warriors. The king of the Visea kingdom was not a nice man. He had 4 sons. 3 were skilled warriors. However, the eldest, William, was looked down upon. While he was proficient as a sword, he served as a strategist for the Kingdom's armies. While the people loved him most of his family despised him. Therefore his father disowned him and exiled him to a distant village. Separated from the Kingdom as a separate country William saw this as an opportunity to build this village into a great empire. And on his journey he will bring concepts and ideas from his own world together. He will meet many people on this journey of revenge. And who knows maybe he will find love along the way?

After World War I, over 70 German ships interned at the British naval base Scapa Flow mysteriously disappeared... More than two decades later in 1940, the world is engulfed in a new war against the Mundus Empire, an invading force from another dimension. Having conquered the Southern Hemisphere and steadily expanding its territory, the Mundus Empire has finally set its sights on the Northern Hemisphere. The United States Pacific Fleet is annihilated off the coast of Hawaii, and the Imperial Japanese Navy's vaunted Combined Fleet suffers a crushing defeat at the hands of the Mundus Empire's fleet that has invaded the Truk Islands. Cornered, the Combined Fleet is relieved by the arrival of a secret fleet of battleships and warships that were supposed to have been sunk as targets under the Washington Naval Treaty, including the battleship Tosa and the German ships that scuttled themselves at Scapa Flow. Resurrected and transformed by the Magitek Research Department, these ships and weapons are Japan's new hope against the otherworldly invaders. Rise, scuttled fleet! RELEASE: 2022 (TL INCOMPLETE)

March 17, 2023.. The day of reckoning that has fallen into this world, whoever created this event surely wants our existence to cease.. I dont know who they are, I don't know what they are, they're creatures that look like humans. But they tamed steel itself forging iron warships that radiates fear and destruction, war machines unlike any other. Just.. who are they? Are they even human.. I cant explain what sort of atrocities have i seen, men die gruesomely, more violent than any war i have ever witnessed. Gore flies out of the mangled corpses of the fallen, and yet despite all dead the destruction still reigns, its horrifying to say the least.. i fear that whoever awakened this sleeping giant.. has filled it.. with terrible.. terrible.. resolve.. By the gods.. make my soul rest easy from this hell on earth, as i take account for my sins.. We need the war to end, before the war will end us.. Disclaimer: this is a fanfic of the story Gate: Thus the JSDF Fought there. Expect it not to be 100% original.

"Time changes so much, huh? Only 80 years and we have Guided Bombs, Super Sonic travel, and we have reached to the stars." -Winston Churchill, c. January 1942 Formerly known as War is Hell. During New Year's eve in 2023, The US is transported back to December 6th 1941, This is what followed.. Inspired by United we stand, Divided we fall by USMCgamer101, This mostly takes a more 'realistic' approach to it, and a larger focus on the politics and fighting, and spying. There is no set main character for this book. I'm a military nerd, not a politician, if I get something with with how they handle politics and diplomacy please tell me in a constructive way! As with any WW2 book, There may be sensitive topics. I do not encourage Nazism or fascism. Viewer discretion is advised, Gore may be described during large battles.

When America discovers a portal to the mysterious Special Region, a land of dragons, magic, and ancient empires, the U.S. military embarks on an unprecedented mission to secure its treasures and power. But their invasion sparks a ripple of chaos, unearthing alliances and rivalries among the region's factions. As the war rages, a new threat emerges-cybernetic invaders from another dimension, drawn to the Special Region's unique magical energy. Faced with an advanced and relentless enemy, the Americans must form an uneasy alliance with the powerful Velthar Dominion and local city-states to prevent the Synthari-a race of machine-enhanced beings-from conquering the Special Region and using its power to dominate all worlds. As soldiers, mages, and mysterious hybrids fight to protect the Special Region, the fragile balance between magic and technology teeters on the brink. Amid betrayals, devastating battles, and unimaginable sacrifices, one question looms: how far will humanity go to control the unknown-and at what cost? A gripping tale of war, diplomacy, and survival, Gate: Shadows of the Unknown reimagines the clash between modern Earth and a fantastical realm, where the greatest threat comes not from within, but beyond.
