Morkoth

From Ardrana

Of all the creatures that inhabit the deep, only the kraken exceeds the morkoth in malice and cruelty. Also known as the "wraith of the deep", the morkoth lurks in tunnels hoping to lure its victims into a trap from which they cannot escape.

The descriptions given by those who have encountered morkoths contain considerable variation, so no one is certain what they really look like. They are usually said to resemble an intelligent fish with an octopus's beak. They are most frequently described as being between 5 to 6 feet long, inky black in color, with faint luminescent silver patches. They may have fins for arms and legs that vaguely resemble those of Humans, and a number of fins for navigation and propulsion in the depths. Morkoths have infravision with a 90-foot range. They speak their own language.

Note: Morkoths originally appeared in this form in the 2nd Edition Monstrous Manual for the AD&D game from TSR. Their use here is for the purposes of providing context for the campaign only.
