Wenelian

Wenelians are a sapient species of slug-like invertebrates from the planet Yundu in the realm known as the Dreamlands.

Biology
Wenelians are slug-like creatures which fly without wings by writhing through the air. Their boneless bodies are cylindrical and can be compressed or stretched to a considerable degree. Their faces consist of a tubular proboscis, two ear-like fins, and two mobile eyestalks. Their skin bears elaborate colorful patterns of yellow, grey, green and ochre.

Wenelian bodies can produce a dense bluish-black mist which, although not poisonous, sticks to the eyes and ears and interferes with other creatures' ability to see and hear. They can also attack by shooting tiny darts of calcite from their proboscis.

Culture and society
Wenelians ride Phosphorescent Monsters through the aether and operate as space pirates, moving from world to world and raiding them.
