Reefs of Etile-viedel
Aquatic beings with a two-stage lifeform and eternal memory.
One of the Scattered Worlds, located in the vicinity of the Human planet Karphos. The people of Etile-viedel are an aquatic race with a two-stage life cycle: as youngsters, they are free-moving and resemble large jellyfish; as adults, they are sessile and live in enormous structures reminiscent of coral reefs. These reefs, laid down over the centuries by the sessile adults, record the memories and experiences of each individual, and can persist for hundreds of millennia.
