Young men, of course, have to be somewhere, but was looking at revising it and concluding they needed more motives. A P.G.

A good marriage would be cheered by their families, and the city is famous for them. (I don't even think they need an heiress.) And finding a post with a king would also be good. Their king would be ideal, though an ally would also work.
