Great Atrocities

The Great Atrocities were a series of evil acts committed over the course of seven months by the air Niphises against the other Niphises on the planet Saelex.

Events
While the Great Atrocities are referenced several times in ancient writings, no specific events are described. It has been estimated that approximately 60% of all Niphises were killed in these 7 months.

Niphetic Calendar
Niphetic years are numbered with reference to the Great Atrocities, either as BGA (Before the Great Atrocities) or AGA (After the Great Atrocities). The year in which the Great Atrocities took place is not labelled at all, often referred to as the "year of the Atrocities."
