Why didn't the Ascians ever go after Koryu?

I was initially in agreement that this is a strong possibility. All of the Calamities we know about were triggered in Eorzea, and Eorzea is said to be particularly rich in Aether. It's not unreasonable to think that those things are related - that Eorzea is the ideal place to "punch a hole" for a Shard's Aether to flood in.

However, a snag with this theory lies in the fact that Tenzen was a Warrior of Light, as well. Why would Hydaelyn set a WoL to work so far from Eorzea, if that's where the bad stuff would need to happen? I think it's quite possible that the Asicans DID have a hand in the whole Koryu mess; perhaps once Koryu began its rampage, the Ascians had some way to direct him toward Eorzea?

We also know there were other WoLs in different parts of the world. Dalmasca/Ivalice had Ashley Riot, Ramza and co with Ultima being the threat there.
