It would work. I wouldn't say build a castle though. The Crane Lion Alliance is strong yes, but having their traditional foes work together keeps the Daidoji up at night, but it would work.
I just figured that "build me a castle" was almost always the thing that got Kaiu deployed by the crab to non-Crab lands. Regardless....
[x] (eyes narrow) "I had been trying to get away from work today, but if I must.... So be it. I will not send her with you as Empress Dowager, but there are other ways."
-[x] Inform the Crab that Hida Benjiro is to officially propose to your mom, and make it look good. When the proposal arrives, inform your mom that she is to accept, as Kaiu Ryoko. Hint strongly to Hida Kuon that he'd be well-served to have one Kaiu Ryoko deployed in some fashion as a representative to the Lion court.
-[x] Let your brother know the rough general plan on the matter, one-on-one. Suggest that for his own sake, he shouldn't let her have *too* much influence at court, as she will be there as a Crab, and that could undercut him with his own people (she's almost guaranteed to push for more influence than she really ought to have). Still, she is your mother, and he is your brother, and you want to help make their lives better.
...because Love in Rokugan is suffering, but being Emperor means you get to cheat. Because serving the Empire doesn't *have* to mean making our family miserable, and shouldn't. Because having mom away from us, married to Hida Benjiro, with our Brother, and *not* officially the Empress Dowager is pretty much better for everyone involved.
...and apparently the Crane get to be the official woobie Clan in this game. Huh.
