Ur wasn't at the level of a wizard saint when she fought Deliora yet.

Whoever it was (can't remember for sure, but was it Hades?) said that if she had survived she would by now be as strong as them, but that was several years after her fight with the demon.

And it was Org who figured out it was Tartaros themselfs who are responsible for their subordinate guilds to disappear, with Doma just agreeing that it was a sound theory.
