Immortal’s Tale Book 1
Their original purpose is necromancy, to revive the dead.
The wizards are trying to break through nature. The mystery of death. They tried to experiment with thousands of corpses for years. When no result, they dispose of the corpse and buried underground. But during the non-stop study of necromancy, the dead bodies rose from the dead with monstrous faces and abilities. It resulted in negative effects and now, after the Celestial Beasts, the Netherworld is facing nightmares.
The ghouls will only attack at night. They are fast, strong, dangerous, and hideous. Whoever can have a close encounter with them will no longer be able to telltale.
