The fourth layer of the Dark Territory belonged to various powerful Warcraft. Actually, the third layer was also home to a large number of Warcraft. The Zorel Elves had been engaged in a fierce battle with these powerful creatures for survival for thousands of years on the third layer. Even though they were currently the supreme rulers of the third layer of the Dark Territory, protected by The Lord of Darkness, beyond the traditional territories of the Zorel Elves, it was still a world dominated by the Warcraft.
The Warcraft of the fourth layer were even more terrifying than those of the third, and not even the Zorel Elves dared to venture there.
It was said that the fourth layer was the habitat of the frightful Heart-devouring Demons, adept at controlling the minds of living beings. These Heart-devouring Demons had established a Kingdom of Heart-devouring Demons on the fourth layer, enslaving various creatures.
