There's one thing I really don't like about this plan, which is that it blows open the return of dragons. But I'm having a hard time thinking of a way of pulling this off without Ryza transforming. A stealth infiltration and exfiltration with Sypha while undetected seems very unlikely, and Ryza and Robin just don't have the firepower to fight their way out.
I do have one idea, but I'm not sure what people will think of it.
[] Plan Keep The Secret
-[X] Perform the half-shift ritual so that Ryza is ready for Mantrae's people to make their move.
-[X] Let them die to get Sypha out. Follow Sypha high in the air until the remaining retainer(s) get her some distance from the enemy, enough to make your move without being seen.
-[X] Dive, grab her without warning, fly for home at best speed.
-[X] Fullshift to fight off pursuit if pressed, such as if the wyvern locates you.
It goes without saying that letting Mantrae's people die only to grab Sypha from them at the last moment is downright cold blooded. This might be the smart play for Ryza's safety, though.
What do people think?
@Jiven, it preserves the dragon for escape.
