Hi guys, I'm a longtime lurker who decide to manifest in the Physical Realm.
I've got a lot of doubts about the exact timeline and cause of the Return: it's not clear to me what we know in detail. I should reread all the books, but right now I don't really have the time! This is my tentative timeline:
1 - Sometime in the past (after the Recreance?): Rayse kills Tanavast (how?)
2 - Centuries before current events, Odium starts condensing part of its power creating the Everstorm in the Cognitive Realm. Could he do that because of Honor's death?
3 - a few years before Gavilar's death, Kelek supposedly starts working with Gavilar and the Sons of Honor to bring back the Desolations. They somewhat developed anti-Voidlight, probably as a failsafe to win the war and bring back the Heralds and the Radiants to their old glory. Axindweth's faction works to manually bring back Voidspren in the Physical Realm from the Cognitive, meaning they aren't captive on Braize.
4 - Around this time, other Heralds are tipped off. Ishar becomes king of Tukar, Jezrien and Nale show up with Kelek the night of Gavilar's assassination. Battah starts working with Taravangian. Szeth starts blabbing about the Return and he's exiled. Taln is free. Spren start bonding new Radiants.
5 - The Everstorm happens.
Questions:
a - did Taln really break? Is that why Voidspren are free in the Cognitive Realm? Why can't the Fused directly take over the listeners without the Everstorm?
b - did Axindweth allegiances simply lie with the SoH? How could "another one of her kind" (I guess the Terris steward) make her flee? Or was she a Ghostblood, given that Mraize hunts who seems to be the same Terris steward?
c - How did Gavilar create anti-Voidlight?
d - why did Kelek work with him? He seems to only want to escape Roshar. Why go together with Nale, which is clearly against the idea of the return of the Desolations?
e - Why did the spren start bonding people again? What happened to Szeth?
f - Why are the Heralds not bound from the Oathpact anymore?
g - What is the proximal cause of the Return? Taln's fall or Gavilar/Axindweth's plotting?
h - Was Gavilar maneuvered by Odium?
Care to pitch in with you best guesses?
