Glowwyrms

Glowwyrms are the gigantic insectile creatures that dwell beneath the Dead Sky just above the abyssal plane.

They hunt using long strings of silk with bio-luminescent globules of glue hanging far below them.

They are actually the adult form of a shipworm. The larva typically finds a ship or rock and creates a den lined with silk.

They reproduce via a parthenogenic life cycle and release a cloud of eggs that drift along in the sky until they encounter a suitable habitat.

The egg clouds resemble a layer of fine dust. Once the dusting of eggs becomes damp they hatch. The minuscule larva start life by eating any and all fellow larva until only one remains which grows to become a full glowwyrm.
