The Dark Forest covered a large area, where the trees were too thick to let the sunlight in. Thus the forest was damp and dark even in the daytime. That was the reason it was called the Dark Forest.
The Dark Forest was surrounded by the Merchant Union, the Fire Empire and the God-blessed Empire[4]. The Merchant Union was to the north of the forest, the God-blessed Empire in the south, and the Fire Empire in the west. Merchants from the three countries had to pass through the Dark Forest to trade.
Demon beasts always made their appearance in the Dark Forest, some of which even reached the 6th or 7th grade. As the trade caravans, soldiers, and warriors crossed the Dark Forest now and then, they knew that demon beasts of a high level only appear in special areas, and those of a low level were usually vagrants.
