Hanchin-set

"Hanchin-set" was a term used to describe the setting of gas giant Hanchin below the horizon of the moon Mina. The term was developed by the natives to the moon to describe the phenomena by which a portion of Mina's surface was not covered by light. One of these rare and brief occasions occurred at mid-winter. During this Hanchin-set, the Vashan bodhis were known to cough up sin-bullets.

The phenomena of a Hanchin-set caused darkness over a portion of the moon, because light radiated and reflected from the gas giant and bathed Mina in a measure of light for the majority of the year.
