Japanese style architecture, mix or English and Japanese style garb, English style town layout with stone buildings and a mix of rolling countryside and grassy wooded areas with pretty streams and rivers? Sleep in beds not on futon, but the short little tables with cushions :P Emperor and Empress, but able to be ruled by either. In other words, if this is the Empress's homeland, she's he head honcho and hubby is the tagalong, and vice versa?

Sorry, I ramble. I'm glad you like my ideas :P War drama does indeed tend to make things a little more interesting *Grin*

Feel free to drop your ideas! If they conflict with what I said above that's fine, nothing is set in stone, I was just popping off some thoughts :P
