Inconsistencies with the sundering (Spoilers)

[Iscah]

Honestly, this is an interesting thing to think about. If Tales of the Dawn didn't exist to correct the inconsistency between ShB's and EW's versions of what the true cause of the sundering was, I would probably go with ShB's version of the Sundering just because I like it more, lmao.

I seem to have missed Tales of the Dawn adding new information on this? Venat's chapter with the Watcher was bogged down in as much vagueness as the cutscene.
