What lore do you ignore?

[Lady_Silvermoon]

We do know that Venat's first measure was to try and mitigate the Final Days' devastation as a whole, but that failed.

What actions did Venat take to mitigate the devastation of the Final Days? Name one.

Her speech about preparation would lead a decent person to assume she means preparation to help and protect the Ancients because that's what they'd do, but reading or listening to it in hindsight, with full knowledge of what happens after, it's clear she's preparing to eradicate her people and replace them. The Sundering wasn't a last option, it was the plan from the moment she heard about the Plenty.
