Ender's Game Wiki
Ender's Game Wiki
This page is a timeline of events. You may be looking for a timeline of novels.

This page documents events in chronological order that took place in the Ender's Game Universe, or Enderverse.

In Speaker for the Dead and chronologically subsequent novels, the "B.S.C." (before Starways Congress) and "S.C." (Starways Congress) dating system was introduced. It was stated to be based on the date of the founding of the Congress.

However, due to many timeline contradictions (mainly about the founding date) between canon sources, this wiki has decided to use its own dating system for use in articles.

This dating system uses an unofficially recognized calendar in order to provide a relative reference to events in the series. The origin year, or epoch, will be based on the date of the Formic Xenocide, as it is the most prominent event in known Enderverse history and localizes the timeline around the first novel, Ender’s Game. The designations used to label years will be BX (Before the Xenocide) and AX (After the Xenocide). Many events will have approximate dates (denoted by "c.", for "circa") or will be listed as unknown, as there are many contradictions between canon material that makes it difficult to know for sure when events occurred.

Dates With an Unknown Era

Muslim Civil War and Nuking of Mecca

This was an event mentioned a few times in Shadow of the Giant as happening many years before its events. This would either put it in the Formic Wars Era or the Pre-Formic Wars Era. However, it was never mentioned in the First or Second Formic War Trilogies, indicating that it may have taken place between 95 BX - 8 AX.

Descoladores Arrive on Lusitania

The arrival of the Descoladores on Lusitania and their introduction of the Descolada to the ecosystem was mentioned as taking place thousands of years before humans colonized the planet. However, this may have occurred in any era except likely the Starways Congress Era. Although it must have taken a very long time for the Lusitanian ecosystem to settle into the way it is by 2916 AX, making the most likely candidate the Pre-Formic Wars Era, it is simply unknown.


  • In The Swarm, the year was stated to be 2118 AD, equivalent to 97 BX.[6] However, in Shadows in Flight, it was stated that Bean's ship left Earth in 2210 AD.[1] This would put the the date given in Shadows in Flight at 5 BX, which does not line up with the rest of the timeline. Hence, the more recently-published date of 2118 is considered canon on this wiki while the date from Shadows in Flight is not.
  • Dates retrieved from Speaker for the Dead and onward are calculated by subtracting or adding the date or years given to or from the Starways Calendar date equivalent to 3000 AX (1970 S.C.). This date is accurate because while the date of the founding of Starways Congress has changed, the 3,000 year difference between Ender's Game and Speaker has not. Thus, we can use it to infer other dates in the BX and AX timescale.
    • Note that while the 3,000 year timescale is very likely to be an estimation and not the actual number of years to have passed, it is the only reliable data point to base dates off of.
