A ball

You look down at Dietrich with his folded list in hand. "I just came out of a celibate religious college. I wouldn't know the first thing about courting, or even what to look for in a girl on some list. More importantly, I need to spend my time learning how to rule."

Sir Dietrich looks up at you, stunned. "With all due respect, your rule will appear weak without an heir. A clear line of succession is key to internal stability." You start to doubt your chosen course. Dietrich is a knowledgeable gentleman, well-versed in the way of rulers.

"If an heir is that important, then I'll just find someone and knock them up so I can get on with ruling the kingdom. This country just lost most of its line of succession, and I need to put all my effort into becoming a competent king before faith is lost in my line, and our coffers are emptied."

Sir Dietrich looks at you with a stern look." "Sire, be reasonable, we cannot let you go ruining your family bloodline with that of a commoner."

"Then let's have a ball and invite some noble girls. I can get it down with whoever shows up, and whoever produces an heir gets the job."

"Sire having you go around and lay with every woman there could create a war with ambitious relatives or worse a full-scale noble revolt."

"Then you're going to have to find a way to make sure that it doesn't ."

Sir Dietrich, understanding your determination, accepts your command, and bows his head. "As you wish, my king."
