Speaking of Colonel Burke Schäfer, he was actually not a real Ukrainian. In fact, he might be a quarter of some fallen British baron's lineage. But in the small surviving city of Horlivka, he, however, had the rights that other Ukrainians did not have. He was the representative of "The Moving Castle" in this place, and also served as the colonel of the Western Front.
Only a few people knew the inner secrets of "the moving castle". It was even more mysterious than the strongest force of Europe - "the Cambrian force". Even Schäfer himself also did not know much about it. He had only entered "the moving castle" twice in this life; and every time he was just staying on the periphery areas of "the moving castle".
