The River of Woe planetary nebula is named after the river Acheron from ancient Greek mythology, where Charon ferries the souls of the dead deeper into the underworld. Both the colors and the shape of the cloud are reminiscent of the waters. Unfortunately, explorers can't admire it from close while they are outside: the closest system is 16 ly away, from which the nebula appears fairly small.

The star of the system has collapsed into a neutron star, and a Water World has survived the supernova. The planet has a relatively thin (0.23 atm) carbon dioxide atmosphere, and its most prominent features are its large polar ice caps. These are visible even on the night side of the planet, lit by light reflected by the nebula: the ice caps glow in eerie colors.

The planet also has a rocky moon of its own, where Commanders can land to view the Water World from outside their ship. However, the planet doesn't appear much larger than the stars in the sky, as it is 1.88 ls away. (It is still easy to recognize with the naked eye though.)

Explorers who have journeyed this far can also visit the Green Aspirant gas giant in the nearby Syrivu AN-M c7-2 system. In addition, there are Chalice Pods to be found in Notable Stellar Phenomena that appear within 500 ly of Crivoe ZG-S d5-12, in systems where there are environments suitable for them.
