Depthshadow Wyrm of the Silent Abyss
A colossal serpent draped in an ever-shifting cloak of shadows glides through the depths of the abyss. Its scales shimmer like oil on water, reflecting the slightest glimmer of light in kaleidoscopic patterns. As it moves, an otherworldly silence surrounds it, swallowing the sound of even the most raucous battle cries. Its eyes, gleaming with a haunting azure glow, can paralyze the unwary with fear. This creature feeds on despair and can manipulate the darkness, summoning shadows to torment intruders in its domain. Adventurers venture into the abyss, unaware of the ever-watchful presence lurking just beneath the surface, poised to strike when least expected.
