I hate to break it to you but time in eso doesn't move forward. We live the same day over and over again. Just take a look at Vivec City. It's been almost 4 years and it's still under construction. Not to mention the cement has dried up in the middle of the crafting area.
Seems like you didn't get it, @Aliyavana. This wiki keeping a screenshot of an old version of this book, before it was changed. Once ZoS were ready to continue the chronology further, but then they caught on to the "helpless newcomers" and caused a lore chaos in 582. That's why I wrote "RIP 2E 583".https://en.uesp.net/wiki/Lore:Birds_of_Wrothgar here's a better source
