[@Bishop] The inherent idea is fine. I'm, motherfucking. marble with the idea that a conquering party became a civilian one. But I don't see how they could become a great house, especially the royal blood line being left alive. The defense are powerful, but in Handon territory on the winning side they would just have to starve them out. Which is easy for forces getting food from non-desert, fertile lands. The king has power, but if he let this arrangement go on. The other houses, especially all the lesser houses in your area would rise up in a civil war. It would be like...letting the germans having an fort in England at the end of ww, staffed, manned and with full county rights. Even if they did disown their own empire the...bad blood be too strong from the locals and other houses. Especially if any royal were in there, whom would probably held most accountable for their nations attacks. If, only, as a symbolic gesture.
