In fact, this may be her first time seeing Tempered in years.
Much as I agree with the auracite theory...
... as their likely power source, it is worth remembering these can be (re)charged, something we know from the very Crystal Tower itself, and she is surrounded by aether, irrespective of whether we think she chooses not to draw on it. As I've said, I don't think it's as simple as she's evil (nor do they generally present things in such black/white terms), but they've left room open to 1) separate the controller/host from the Primal, which is an easy way to attribute her statements about the world's history to misconceptions and 2) it's entirely possible her group of summoners was deceived by some third party... i.e. the very one now setting in motion the Final Days 2.0. While a waning crystal is certainly a probable explanation for the silence, they have enough room for it not to be the only good explanation.
