On the other side of the battleground at the 50-meter-long battleground, Castiel, Damon, and Serhan were handling the rest of the noble students.
Sure, they were outnumbered but thanks to night mist from both Castiel and Damon, the other students had changed from teaming up to attack them to self-preservation.
The darkness element was overpowered especially the spell night mist. The only way to counter it was to either use the light spell, revealing light, or move out of its area of effect.
Almost half of the battleground was covered in thick black mist, so everyone within it tried to escape from the sides, but that was the plan all along.
Once they had activated night mist, Castiel and Damon made their way out of the mist. So if any of the enemy students didn't get eliminated by the falling pillars and managed to escape the black mist that was constantly draining their vitality, they would be ganged up by both of them.
