The time before the War of a Thousand Suns, known variously as Pre-Holocaust, Pre-H, the World Before (by the Iron Masters) and the Old Time (by the Mutes).
The Pre-Holocaust era, accounting for the bulk of human history, is held to have ended on 17 November 2015 when the war took place. The Iron Masters and Mutes only have fractured and disjointed legends and myths about this time period, but the Amtrak Federation has an extensive archive of Pre-H historical records and cultural items, which it rations most carefully to its citizens.
