Why didn't the Ascians ever go after Koryu?

True. But I feel like the Ascians could figure something out. They are master manipulators after all.

Well, considering that a Warrior of Light dealt with the problem, whose to say that the Ascians didnt try to do something with Koryu before he was sealed. Afterwards, he was sealed with a crystal of Light, so i dont think the Ascians could do much there.

This is my feeling too. Tenzin had some aces in the hole as well with his Four Lords comrades and the various other lesser auspices that might have gathered around him during that time. While Tenzin and the Four Lords may not have known about the Ascian's per se, they knew enough to understand the threat Koryu posed and took steps to deal with it.

Related to this, it makes me think about the aramitama and it's effects via the Lifestream. What is it exactly? Is it perhaps related to the Calamity that brought about the fall of Amaurot etc.? Or maybe it's something that was seeded by the Ascian's in an attempt to destabilize the Source in preparation for a Rejoining? It would stand to reason that, with the presence of other WoL's throughout time (Ramza, Tenzin) there were probably other attempts made by the Ascian's that were foiled by Hydaelyn's chosen. In that sense, perhaps the aramitama is some kind of foreign influence applied to the Lifestream with the express intent of disrupting the balance of powerful beings in the hopes of causing chaos that could then be leveraged to force a Calamity/Rejoining.
