The Garlean Empire vs Omega

[Zero-ELEC]

And that is fine too. Estinien being immune to the effects of Nidhoggs corruption is cool. Guy is a badass.

Getting conflicting arguments. Was Estinien influence by Nidhogg's aether/possession in a permanent manner or not?

No conflicting argument. He was not influenced permanently as far as we know or can tell, at least inasmuch as his personality is concerned. His rage was temporarily synchronized with Nidhogg's and he called upon him for more power in the A Realm Reborn job quests but managed to shake it off offscreen, and once possessed of both eyes of Nidhogg and covered in his aether-rich blood he was taken over by Nidhogg's lingering will but was freed from this by Alphinaud, the Warrior of Light, and the lingering wills of the Ysale and Haurchefant.

His changing attitude towards dragonkind is attributed to his experiences, rather than any aetheric influence. Anything else would be convolution of story and really isn't supported by the game's text.

Sorry I came off as angry or annoyed in the other post, I was in a particularly foul mood when reading those posts and drafting the response and almost immediately regretted my tone.
