Hello everyone, I am currently listening to book 12, chapter 13. I feel so confused about this whole time line. Last I understood, Jason had to leave for a couple of years to fight with the astral beings over the Sundered Throne. When he comes out and goes to see the bright hearts, how much time has passed? I though it was four years, but now I think it's 12 or 20 years he's been gone? I found a timeline on a wiki page but that just confuses me more.

I would really appreciate any help on this. Please, no spoilers past where I'm reading.
