Relic War

The Relic War, also known as the Crossdimension War and the War of the Relics, is an interdimensional war taking place during the year-long Great War and a few months after Novayan reconstruction efforts.
The Relic War when German excavation efforts unveiled a relic of unknown power that allowed the German Third Reich to rebuild its forces and develop new weapons of war in part of a secretive division, the SS Paranormal Division. Though the German Third Reich conquered most of Europe and more than half of the United States, the conflict began only when the Greater Germanic Reich expanded into Hell, the so-called "world with unlimited energy", which pits the German forces and the victors of the Spellcross War, especially the Novayan Commonwealth, in series of skirmishes and later battles that drove the Germans out. With support from the Human Alliance and the International Union, the Novayan Commonwealth deployed its forces into the Western United States; although encounters between the Novayan and Allied forces were tense at first, both worked together into fighting the German forces.
After several information exchanges between the Human Alliance and the International Union revealed what is going on to the Human Alliance, the Novayan Commonwealth, out of its own initiative, deployed its forces to coordinate a three-pronged counterattack in conjunction with the Allied Forces, leading to the liberation of the occupied United States. Even though General MacDouglas sought to use the Relic Gate to not only defeat the Germans but also the Soviets and the Japanese and rule the world for America, it was made clear to him by Human Alliance emissaries that the Novayan Commonwealth will not take any betrayals, especially his own would-be betrayal, very well as the Novayans will lash out at their betrayers very violently, referring to his actions as "nearly choosing death".
The Human Alliance and the Allied Forces launched numerous theaters of military operations against the Axis - Operation Longsword (military operations against the Greater Germanic Reich), Operation Setting Sun (military operations against the Japanese Empire), and Operation Mediterranean Cross (military operations against the Italian Empire).
The war ended in the defeat of the Axis Powers and victory for the Allies and Human Alliance despite the Novayan Commonwealth occupying the Kingdom of Italy and the German Third Reich.
