The moons of Heroshi are said to be droplets from Cura's cup of mercy. These luminescent spheres, which vary in size and color, are spheroid in shape when still.  A moon in motion, however, somewhat resembles a whale composed of sea water.

The Lunar celestials are their guardians and caretakers. They cause them to appear in Heroshi's sky at night, moving them around and adjusting their brightness as needed to provide signs for mortals to interpret. Curan priestesses often provide moon readings for the town they reside in.

The moons are named:

Procellarion - great storm, major tribulations

Frigorum - cold, death

Serenitis - serenity, peace

Tranquilatia - tranquility

Crisius - storm, minor tribulations

Fecondium - fertility

Nectaria - nectar, healing

Vaporius - vapor, uncertainty

Nubius - clouds, hidden

Humorium - moisture, nurturance

Imbrius - rains
