In a last resort, he could only redirect his high-level Black Fire Cultist guards to the central area to fortify the defenses.
The more than ten Black Fire Cultists in black robes, riding Low-Born Demons and brandishing flails, did appear quite imposing as they charged in a frenzy. However, at this time, the Silver Elf Guards in silver armor had already rushed forward to stand alongside Brand, while the surrounding Lizardmen attempting to encircle them were continuously subjected to remote attacks by the mercenaries.
If the Dark Priest commanding this had been a bit calmer and had ordered the Lizardmen to abandon protecting him and instead assault Brand's remote position on the slope, the scene might have looked more favorable. But unfortunately, the art of command was not the priest's forte. He could only instinctively order the Lizardmen and Black Fire Cultists to gather towards him, partially to avoid being split and partially to better protect himself.
