Eighth Great and Bountiful Human Empire

The Eighth Great and Bountiful Human Empire fell to the Deathsmiths of Goth on 10 July, 9967. (PROSE: Time Traveller's Diary)

Behind the scenes

 * The Fourth Great and Bountiful Human Empire existed by the year 200,000 (TV: The Long Game), several millenia after the Sixth, which, according to Time Traveller's Diary, existed by 9967. This is likely an accidental continuity mistake.
