It seems like that would undermine her character's point.
"The one person to stave off the whispers and who spawns a cult following that also has to contend with the whispers, also falls prey to the whispers like countless others before.".
I mean it's not impossible, but at this point it just makes the introduction of both her and her void elves more than a little curious, if not downright redundant due to us having seen this story repeat so often.
Thus i believe she will remain the inverse of the common trope, at least for a while: The all-corrupting power resisted, for once.
Also it'd be weird to keep the void elves around if she succumbs to the void already.
