Because he was the previous lord and duke of the region, and only lost it because the region starved when you cut Dwilight's food supply?
A ruler can make himself duke of an existing duchy. A ruler can create a new duchy. Why can a ruler not combine these two?
You are simplifying the argument and thus missing the answer. If you go through the full process of how these happen, you see immediately why.
I'm sick and tired of having arguments on this forum. If you have a suggestion, make it and it will be accepted or rejected. This constant bickering back and forth and arguing for arguments sake is causing frustration and nothing else. So to save everyone the frustration: Bad luck, this is how it is, I will not change it, period, end of discussion.
