Aboleth

Aboleths are ancient and enigmatic aquatic creatures of immense power and intelligence. Dwelling in the darkest depths of subterranean lakes, underground rivers, and sunken, forgotten cities, these serpentine monstrosities are among the most feared denizens of the deep. Aboleths possess elongated, sinuous bodies covered in slimy, mucus-coated scales that shimmer with eerie bioluminescence in the darkness. Their heads are elongated and feature a single, enormous, unblinking eye that radiates an otherworldly, malevolent intelligence. Tendrils protrude from their mouths and wriggle menacingly, allowing them to manipulate objects and creatures with unsettling precision.
