The horns pulsated with a malevolence that transcended the physical. Each beat seemed to synchronize with the rhythm of the abyss, creating an aura that resonated with the demonic forces that fueled the demon lord's power. The pulsating malevolence was palpable, an atmospheric phenomenon that radiated from the twisted obsidian spires.
The horns, in their twisted ascent, functioned as a crown of demonic dominion. They marked the demon lord as a sovereign of the abyss, a ruler whose very presence disrupted the natural order. The horns, adorned with an air of regal malevolence, accentuated the demonic countenance that commanded the loyalty and fear of those within the fortress.
