1 AC

Year 1 or 1 AC (After Creation) of any world is the year in which events "start to happen", when civilizations are declared to be created. Everything before that is declared to have happened "in a time before time" and that characters born before year 1 were "one of the first of their kind". However, programs that extract data from Dwarf Fortress such as Legends Viewer claim that there are clear dates of birth for creatures before year 1, going as far as the year -400.

Notes and references

 * Legends Viewer claims there exists a Year 0.
