We've assumed that Taln broke, and that was what allowed the True Desolation to start. Now though, we know that the Everstorm had been brew in Shadesmar long before it was actually summoned to the Physical Realm and was used a sort of backdoor for Odium's forces. Now, I'm not convinced that Taln broke. The Oathpact had already been weakened, so maybe this backdoor created a loophole. Taln could have slipped through it as well to try and warn Roshar. What do you guys think?
