I'm playing WFRP 2 Edition but our campaign started bit later that default 2525 IC.
I want to know if there is any additional information about world events in WRFP 3 Edition that can influence our campaign.
The WFRP 2e Setting starts in 2522-2523. Specifically, the Storm of Chaos outlined in WFRP 2e states the war end, with the armies of Archaon, The Lord of the End Times, in full retreat from Middenheim at the beginning of 2523.
WFRP 3e resets the clock well forward of the Storm of Chaos, specifically near the end of the WFRP 1e (yes, the original) The Enemy Within campaign, near the end of Something's Rotten on Kislev.
The Enemy Within(1E) specifically starts in year 2512. This is stated in the module and the calendar for that year is provided. This puts the Storm of Chaos a full decade later. Something Rotten in Kislev and Empire in Flames (or Empire in War, depending on the transitional narrative the GM wishes to offer) compress this time line a bit with a common sense narrative of travel in the Old World. The events in Empire at War for instance are scaled almost a full two, in-setting, years; it just takes that long to travel the distances and account for encounters. I can't speak for The Enemy Within being a decade in scale, but it is possible.
If you want more about the setting, considering watching the series of Jay Little at GenCon 2009 and look for Darkness Rising on eBay.
