First Age

The First Age or FA is a term added to the Keyonian Calendar to label the dates from the years 4000000000 to 1 before the Nova War. Anything after this point is considered the Second Age, or SA.

Originally, the dates were written in terms of eras named after grand events at the time. For example, the dates from 77439 FA to 77390 FA is within the Keyon Era. After the Nova War, this was changed so that anything prior to said war is considered the First Age.
