Benthic Subspecies
Benthic dragons are inhabitants of the deepest reaches of the Leviathan Trench. Even to their clans they may be strangers, surfacing only rarely from the depths. Within their preferred environs, they are the most fearsome of predators. They blend in with the unlit black of the sea, using their spines as lures to draw in unwary prey. Many fish, deep-sea octoflyers, and other creatures have chased what they thought to be a glowing worm and bitten down only to find that they have snagged the tail-tip of the dragon who now coils around them, squeezing away their life.

Benthic dragons live amidst the darkest of the Tidelord's prophecies, those so burdened and heavy with disastrous or malevolent portent that they do not float up from the Spiral Keep, but sink below. Benthic dragons listen to these whispering oracles, absorb their predictions, and whisper back. Where Benthic dragons go, death and misfortune follow, and to hear their sibilant murmurs is to court madness.
