Flumph

Flumphs were mysterious and benevolent creatures that drifted through the Underdark.

Description
Flumphs floated by means of an innate anti-gravity field, and moved by using air jets as propulsion. In fact, they were named after the characteristic sound made by these jets.

Flumphs also glowed faintly in different colors depending on their mood:
 * Pink: amusement
 * Blue: sadness
 * Green: curiosity
 * Red: anger

Personality
Flumphs were wise and possessed advanced knowledge of philosophy and other subjects. They fed on psionic energy and were therefore more likely to be found near strong sources, such as aboleth, gith, and mind flayer settlements. However, due to their strong telepathic nature, flumphs were very sensitive to evil thoughts and felt the need to share them as quickly as possible with any good-aligned creatures they found, in order to wash these thoughts away.

Combat
Normally, a flumph's reaction when facing an evil creature was to flee. However, flumphs' tendrils were acidic and could be used as defensive weapons if necessary.

Society
Flumph society was organized in harmonious cooperative groups called "cloisters", in which all flumphs contributed according to their own skills. They were also known for sometimes recruiting isolated mindwitnesses into their communities. Once a mindwitness was taken in service of the flumphs, it would change its world view accordingly and was no longer an evil creature.

Flumphs were largely ignored by mind flayers, who had no interest in them. For that reason, it was relatively common to find cloisters of flumphs near mind flayer settlements. On the other hand, githyanki abhorred flumphs violently, and attacked them on sight.

History
The origin of the flumphs was ultimately a mystery. It was speculated that flumphs were genetically related to grells or belabras, due to some physiological similarities such as their hovering and the presence of tentacles. Given the probable genetic ties to the grells, most sages agreed that flumphs originated in a different world and traveled as clandestine passengers in grell spelljammer ships.

During the late 1480s DR, flumphs were greatly disturbed by the demonic madness that permeated the Underdark. Some offered assistance to anyone who opposed the derro cultists under Gracklstugh, while a cloister of flumphs from the Wormwrithings maintained that kindness was the only appropriate response during those evil times.

Around 1492 DR, a cloister of flumphs inhabited Undermountain, feeding off the psionic energy of the nearby illithid and githyanki settlements.
