There was a point during the MSQ where they were deciding on a time frame. While our character was sleeping at the Inn after the run we had through the Malikah's well and the pain attack we had from the nascent light breaking free, we got visited by G'raha and we had an echo dream (at the time we didnt know it was him in the future) of him at House Fortemps closing Edmont's book. He basically said that after the dragon song war that was too early to summon us and would it possibly be better if it was after freeing Ala Mhigo. They just needed to figure out exactly when after that.
