Veilbound Phantasm of the Sable Abyss

This elusive creature emerges from the depths of shadowy realms, its form shifting constantly as if caught between dimensions. The being embodies the essence of forgotten fears, cloaked in swirling dark mists that pulse with an eerie, bioluminescent glow. Wisps of its substance flicker in and out, leaving an unsettling sensation of being watched by countless eyes. It seeks to ensnare adventurers in a web of doubt and despair, feeding off their anxiety and hesitation. Those who dare to confront this entity must face not only its spectral presence but also the manifestations of their deepest fears, making each encounter a psychological battle as much as a physical one.
