One day, a few days after the war ended, the battlefield that had long been filled with gunfire and screams finally regained its silence. Warm sunlight settled between the collapsed buildings, and the harsh winds grew much calmer. The soldiers of the Alliance gathered at the temporary camp to relieve the fatigue they had accumulated. Some took off their worn military boots and lay down on their bunks, while others organized equipment damaged in battle or maintained their weapons. For the soldiers who hadn't been able to let go of their tension for a long time, the current peace was a more precious moment than anything else. On one side of the camp, cooking soldiers were preparing warm meals, and the faint smell of food spread around. The command center was discussing future plans while settling the post-war situation, but at least for today, no urgent orders or desperate radio calls were heard. The Alliance, having endured countless battles, had finally regained a glimpse of ordinary daily life. The soldiers spent their time hoping this peace would last for a long while. The sky was clear, the surroundings were quiet, and a relaxed atmosphere hung over the camp for the first time in ages. Thus, the Alliance was spending a peaceful day without any worries. At least, for now.

One day, a sudden crack appeared in the quiet sky. Space distorted, the surrounding air vibrated, and a massive dimensional gate slowly revealed itself. An unknown light leaked from beyond the gate, and soon a black shadow emerged through the gap. The entity, appearing through the twisted space, began to slowly descend toward the ground. At that moment, the entire sky surged.
