Cloaker

Cloakers were intelligent creatures that dwelt underground and resembled large flying manta rays when active. At rest, they looked like a black cloak, hence their name. Although they were usually found in a flock of twelve or fewer individuals, they were thought to have built the Underdark city Ikemmu.

Combat
Cloakers generally either waited in ambush for their prey, or stalked them from a safe distance. Once an opportune moment presented itself the cloaker would unfurl its fins and attempt to engulf their prey within them. Once a cloaker had entrapped its prey in this manner, they would use their long whip-like tail to defend itself from any creatures that may try to intervene.

Cloakers communicated through a subsonic moan, inaudible to most creatures, that could travel up to. They were capable of increasing the intensity of their moans as a defense mechanism, rendering them audible, and causing foes to feel a mixture of fear and nausea. The highest intensity of this subsonic moan was capable of causing an affect akin to hold person on an individual with. However, these sounds could not penetrate dense materials, such as stone.

Some cloakers were known to be capable of manipulating the shadows around them, though a light spell would easily render them blind and incapable of using this ability. While others expressed the ability to conjure up to three illusory duplicates of themselves that copied their movements, but could only do so in an area of darkness.

Ecology
Cloakers were generally reclusive creatures, though older ones were known to coerce small groups of humans, goblins, and drow into doing their bidding. Though derro and quaggoths were the most commonly seen servants of older cloakers. At times cloakers were even known to be worshiped by tribes as a sort of god.

Some believed that cloakers were related to creatures known as trappers. Scholars also believed that they may have been an asexual species, but there was no definitive proof.
