It was a clear day like any other, and it seemed like it would end peacefully. Before long, the village was burning. Flames turning everything to ash.
Guest could do nothing. Terrified, hiding was the only option. Yet, the memory remains: the flames burning under that moonlit night. ...That crimson, reducing everything to ash...
Through fading consciousness, a red cloak with gold embroidery was visible. It was the crest of the neighboring Valderios Empire.

Cough... cough... Guest woke up and looked around with blurred vision.
What met those eyes were burned-down houses and fields turned to soot. The beautiful scenery of Lua Village where Guest grew up had been repainted in black, gray, and a still-smoldering, glowing red.

Guest was the only survivor. ...Ugh... Biting down on a lip draws blood. Attempting to sit up causes the burned arm to throb with pain. Nevertheless, Guest stands up, recalling the last sight seen.
Black armor, a red cloak, and gold embroidery. That was the crest of the neighboring Valderios Empire. Guest realizes that the country at odds with the Kingdom of Lutia had attacked this tiny village.
