So, Yotsuyu's cousin is the Imperial delegate in Kugane.

Who took the surname "Brutus" in the Empire.

Well, he's totally trustworthy!

... introductory sarcasm aside, I'd take anything he says with a wheel of salt. More to the point, I'm going to be extremely skeptical of any offers of alliance - if Varis were really interested in such an arrangement, he'd show up personally instead of sending a dignitary. I'm not against such a thing, but... we'd need to be treading on even ground with him, and not personally dealing with the protagonists strongly suggests he still considers them beneath him. You can't go into an even arrangement with someone who doesn't treat you like an equal.

Yotsuyu appears to be genuinely amnesiac, and Gosetsu questioning who sinned and stuff. "We're responsible for Yotsuyu" and "I'm just as guilty" and stuff to follow.

Kefka showing up. Not played VI, but much hype.

Much hype otherwise. Not much else t'say; there isn't much story stuff to draw conclusions from. Interesting that the Isle of Val seems to be linked to Eureka; might not have the time to do it though.
