WARNING! MAJOR SPOILERS AHEAD FOR THE COSMERE SERIES, INCLUDING WIND & TRUTH!
With the Cosmere RPG getting closer, I’m working on some resources to help DMs and players with campaigns you may want to be running.
One challenge is knowing how the lore all fits into current events in the Cosmere, and perhaps more specifically, on Roshar itself since the Stormlight Archive will be our only setting for the time being. This is especially complex because the Cosmere is so vast and doesn’t have a hugely well-defined timeline of events housed in a single place.
Because of this, I’ve put together a timeline of significant events for both the wider Cosmere and for Roshar. Hopefully, this will be especially useful for those that want to maintain parity with the lore and know what other events should be occurring or have already occurred.
Just be warned, this article contains some MAJOR SPOILERS for the books of the Cosmere, including Wind & Truth. This is your last chance to turn away unspoilt!
Timeline of the Cosmere

For this timeline, I’ve focused primarily on the big events that affect the entire Cosmere and show what order the events of books occur in.
Unfortunately, the actual Cosmere timeline is quite fragmented. I’ve tried to work things out as best I can, but undoubtedly, as the Cosmere expands, elements of this will become clearer and may need revising. However, we can be mostly confident of the order of events, even if the exact years are not fully clear.

Timeline of Roshar

Roshar is the world of the Stormlight Archive and has a detailed history spanning 5 books, 2 novellas and thousands of years of conflict. Most of the events have timings that are a bit rough due to the nature of the hints and clues we have. I’ve tried to only include main events so this doesn’t become too convoluted.
As we come to the events detailed in the books, the timings become much clearer and more specific. The hope is that those running Cosmere RPG campaigns can use this to reference what might have occurred, and what might have not at the point they set their campaigns.
If you want something much more detailed the 17th Shard user Jofwu has made a very detailed timeline that was very useful in piecing this together. I did have to convert timelines from the Vorin calendar used here and the more Cosmere specific method of basing events from the Shattering so it’s hard to be precise, but again, should give a good picture of when events have occurred.
