Sundering stuff established in the Q&A

[LystAP]

- Venat left Emet, and ambiguously the other Unsundered, alive on purpose because of their utility in bringing about her plans.

This means Venat was responsible for the Ascians and the Rejoinings, alongside the tragedy of the 13th Shard. The Ascians were able to reconstitute themselves as their core members were Unsundered. If they all were Sundered, they wouldn't have been able to pull off the Rejoinings. Much less even remember if there was a unsundered world. If Venat retained her memories of the WoL, then she willingly pick the path that would result in all the tragedies of the Umbra Calamities.
