The echo and Hydaelyn's contact

[Veloran]

Fandaniel is proof of it because he was already acting on his own before Elidibus was defeated.

There's not any proof that Fandaniel was tempered.

In fact if you think about it, it's impossible for any of the Sundered Ascians to be tempered. So far as we know, tempering doesn't persist through death and a dunk in the Lifestream, and all the Sundered Ascians were raised up from shards of their original selves after the Sundering.

And Zodiark, again so far as we know, is extremely dead. He shouldn't be able to temper anyone.

If She is expected to target Zodiark, and Zodiark no longer exists, then what reason is there to act to limit His power?

If Zodiark is set to be resurrected, she has reason to sunder the world once again.

Also, I really think there was an alternative reason for the Sundering, something more than just killing Zodiark.
