It was a late autumn afternoon, the sun was shining brightly and there was no cloud in the sky. In the east of the mainland, close to the border of the Eastern Empire, the forest of Obnor stretches for thousands of miles. It is said that this is the place where the legendary general Grand Duke Obnor chose to fight the Eastern Emperor's army to the death. He relied on the forest defenses that no one could cross, and used the canyon on the western front as a strong danger to force the Eastern Emperor's army to fall into a trap. After burying 200,000 Eastern Emperor men, the situation on the eastern front of the Northern Act was stabilized. Obnor also gained the reputation of a legendary general.
