"Who...what are you?"

[Kallera]

Thordan was in a position of authority with the influence to transition Ishgard into a less socially imbalanced society and therefore avoid potential civil unrest. Lets be clear. We had already removed Nidhogg when Thordan left. He didn't need the power of a primal to defeat that dragon anymore. The Horde had had its head cut off.

Thordan needed the power in order to best the Ascians, beings we cannot be relied upon to kill without considerable set up and expensive rocks. It was a surprise that Urianger found even a second for us to take with us to azis lla.

Even with Nidhoog dead, the lands of dravania is rife with proof of letting Ascian meddling go out of hand. And Thordan clearly had a deal with these beings. He wanted(and, in his view, needed) to put one over on them or Ishgard's society would never be safe.
