Cloakers, or fulthrethus, look like monstrous manta rays that have long tails that end in a bony whip. Horns beside their heads end in thumb-like claws and are as black as their oversize skin. Their underside is pale and it contains a fang-filled mouth and two red eyes. Their wings spread farther than a grown man can reach, and they fly quickly at an average quality.
When the aboleths destroyed Old Azlant, they cast out the cloakers, who fled to the Darklands. Most aquatic cloakers returned to serve the aboleths, but the remainder informally serve the Great Old Ones.
There are several variant types of cloakers, from amphibious, to assassin, fungoid, halfbreed, priest, shadowbrood, stinger, vampire, and webspinner.
