What is Pathfinder Society changes in Golarion?

[Kavlor]

I know that certain seasons of this game have led to significant changes in the world. The story arcs of the Elemental Lords and the Ruby Phoenix, as far as I know, originate there. However, I have never found any information about what many seasons have changed.

Can anyone help and give me a complete list of the changes each season has had in Golarion?

I would use the PathfinderWiki. (It's a bigger answer than can be put into posts on The Boards.) Each Season of PFS has its own page 'overview' on the PathfinderWiki giving a general summary of the Season as well as a list of the Scenarios.

You can do the same search on the PathfinderWiki for Adventure Paths; I would say they change the Campaign setting more than PFS.

Come back with some 'smaller' questions with answers that can be a bit more specific -- there's tons to give.

Lost Omens: Pathfinder Society Guide covers a number of their 1e plotlines, as they've now become 2e backstory. My favorite is the restoration of Jormurdun, a Sky Citadel in the Sarkoris Scar that had Numerian time magic displace the original inhabitants!
