After Cassius became a hero, his life was not as peaceful as he imagined. Although the Dark God was repulsed, the impact of that battle still spread across the continent of Azeroth. From time to time, some residual phenomena of darkness appear on the continent, such as crops in some areas withering inexplicably, and some villagers falling into strange slumbers.
The college began to organize an investigation team, and Cassius and his roommates were naturally the core members. During an investigation into a remote village, they discovered some strange black runes that exuded a faint dark aura, which was similar to the aura of the black-robed man they encountered in the misty forest. This made Cassius realize that the Dark God's power may be more entrenched than they thought.
At the same time, there are also some discordant voices within the academy. Some students were jealous of the glory Cassius and the others had gained, and secretly hindered them. Cassius felt these changes, but he had no time to pay attention to it because he knew that a greater crisis was still waiting in the dark.
During the investigation, they followed the clues of black runes to an abandoned castle. There was thick fog surrounding the castle, and the walls were covered with thorns. When they entered the castle, a powerful dark force rushed towards them, as if there were countless pairs of eyes peering at them in the darkness. They know that new challenges are about to begin.
