A science-fantasy crossover, that asks "What If the World of Arknights met the 21st Century United States." Beneath the classified depths of Area 51, a decades-long black project known as Project ARKSEK has achieved what was once thought impossible: the creation of a stable, functional gateway to another world. In the wake of this discovery, the United States mobilizes its most advanced and sophisticated military units and scientific minds to establish the first Human presence beyond the Gate. However, this new world known as "Terra" by its inhabitants is no empty frontier. It is a world shaped by its own complex History, Societies, Nations, Geopolitics, and scarred by Catastrophes. Home to diverse nations built upon the foundation of Originium, an enigmatic energy rich mineral that fuels entire civilizations, but also spreads a deadly disease that has no cure, known as Oripathy. What begins as an exploration mission slowly becomes something far more what the US could have ever bargained for in another world. Fraught with discoveries and dangers unlike anything humanity has ever encountered before. As American forces attempt to understand and navigate this alien yet familiar landscape, they will be forced to confront questions of Morality, Control, Diplomacy and weighing the cost of Intervention. What they will find on the other side may change the future of both worlds. For better or for worse. Every discovery always has a cost. And some doors, once opened, cannot be closed.
