A mysterious portal strands a modern multinational military force in the fantasy world of Siyea, a land of medieval kingdoms and powerful magic. The technologically superior Earth military, equipped with tanks, jets, and satellites, suddenly finds itself the dominant power in a realm ruled by plate armor, dragons, and fireballs. However, their overwhelming technological advantage is immediately tested by a fundamental cultural and ideological clash with the world's native civilizations.

The three major nations react in starkly different ways. The magical Republic of Eneyr, home to long-lived elves and arrogant mages, declares a "Purification War" against the "Soulless Ones," viewing Earth's machinery as heretical "dead magic" that corrupts the natural world. In direct opposition, the spiritual Kingdom of Neru sees the newcomers as bearers of a "Great Enlightenment" and eagerly seeks alliance and knowledge exchange. Meanwhile, the feudal Empire of Ver remains cautiously opportunistic, assessing whether to fight the new power or hire it as the ultimate mercenary force.
