As we all know this game is filled with lots of lore, and even teeny tiny bits.
I'm preparing some simple animations (and by preparing I mean figuring out an art style) based on istaria lore (Age of Dragons, Rise of the Aegis, Nyrevin's Apologies, etc.), and while I was writing down ideas, I ran dry after a while.

So I decided to come to forums and ask the community:
What is your favourite Istarian lore and where can you find it?
