Why do Diemed's problems all seem to relate to marital issues one way or another?
Marital Law:
"Everyone have to remain in the gates and marry within two days."
I can only assume it is an effort to raise the level of the province.
Hah! We had something very close to that in our tabletop game. When we ran into Osoerde, Raenech's provinces were all much higher than they 'should' have been. When we started Espionaging the kingdom, the DM informed us that, among other things, Raenech had passed laws requiring the folks in the border provinces to house his soldiers... and giving those soldiers legal right to demand conjugal visits with the ladies of the household. The products of which unions went into what amounted to state-run orphanages. He'd spent the past 20 years (the timeline of this game varied in places from standard) breeding his province levels up.
