After the war, at the center of the rainforest, they had reached the end of the battle. Everyone had gathered at the nearest village, which is the closest to where they are. The group, which was made up of a few hundred, was only able to return. Some had perished in the battle and died on that battlefield. Deaths cannot be avoided in war, especially when their opponent is a lot more powerful than they are.
The one who had done most of the job had fallen into a deep sleep and was allowed to rest in the most comfortable location in the Elven Village. Though there is quite a lot of death count, just the fact that they killed the two dangerous variables in the rainforest is more than enough for the races that live in this place to become worry-free. They no longer have to avoid venturing at the center of the forest as the Ancient Tree God is no longer there. There will also be no miasma in the forest as the demonic being was killed.
