Darkfish

When a dark cavern, deep fissure or the tunnels of the Underdark are talked about in hushed tones, none mention the darkfish. The silence isn't due to fear or uncertainty, but from complete unknowing. Those who have encountered the darkfish have never returned to tell of it. -- From "The Fauna of the Deep"

Horrors Untold

Deep in the intertwined latticework of the Underdark, or roaming openly in the Shadowfell are the darkfish. Huge, stone scaled creatures with jagged, cruel teeth and claws, darkfish prefer the long hunt, driving their prey to exhaustion before finally going in for the kill.

Few have ever heard of these creatures, and fewer still have been lucky enough to survive the terror of being their prey. Those who do are often left scarred and broken, both in body and mind, and babble incessantly about glowing eyes in the pitch black darkness. Most speak also of the cruelty of these creatures, and the horrendous torture exacted by them.
