Timeline

For Skytopian events, BU means "Before Upheaval" and AU is "After Upheaval". The "Upheaval" referred to here is The Great Upheaval. Skytopian years (AU) are measured by real-life months. In February 2011, the Skytopian Calendar year was 239 AU.

This timeline is player created and is intended to serve as a general 'sequence of events' reference. The conversion of real time into game time is 1 real-life month to 1 Skytopian year. Known problems with this rate are that characters age quicker than intended and that the Hidden War does "a little warping of time".

The Devs have mentioned that they intend to release an official timeline someday.

Canonical dates
Echoes of History states that the Great Upheaval occurred "some two hundred odd years" before the Tortugan Upheaval.

The Hidden War stories written by the volunteer RP Guides contain dates from the player timeline: 203AU as the capture/pardoning of Verron Kadath and 232AU as the current year. Using the player timeline causes continuity problems, for example: if the Legacy Operation occurred in 207-8AU, then Kadath was pardoned to study Wutaryoo years before Wutaryoo was discovered; and if SR2.4 started in 214AU, then Acolyte Steven and Olivier Babbington would have been members of their respective factions for at least 18 years as they were amongst the first join. Further problems are introduced when analyzing the text of crew members, specifically the cynical ones who comment about having joined in the Upheaval Wars, which would require them to be more than 150 years old by the current player made time line.
