Homebrew Flumph Species Details

Flumphs feed by siphoning mental energy from sentient creatures, and they can be found lurking near communities of mind flayers, aboleths, gith, and other communities of Underdark denizens. As passive parasites, they take only the mental energy they need, and most creatures feel no loss or discomfort from such feeding. Consuming psionic energy reveals the thoughts and emotions of the creatures on which the flumph feed. Since so many of those creatures are evil, flumphs are often subjected to thoughts, emotions, and hungers that sicken their pure nature. When flumphs encounter good-hearted adventures, they are eager to share the dark secrets they have learned in the hopes of casting down their evil sources of energy, even if doing so means they must seek out new sources of nourishment.

History

The origin of the flumphs was ultimately a mystery even among flumphs themselves. It was speculated that flumphs were genetically related to grells, 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 came to this one via the same way the grell did.

Society

Flumphs live in complex and organized groups called cloisters, within which each flumph has a place and purpose. These harmonious groupings have no need for leaders since all flumphs contribute in their own way. They were also known for sometimes recruiting isolated mindwitness 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. If you make a flumph character it is a good idea to make a short history about the cloister on which you came from so your Dungeon Master can perhaps use it later on. Alternatively, you can roll on the table below to see what your cloister was like.
