Lo folks, two questions.
Do grail knights leave their families when they have drunk from the grail. That doesn't seem very chivalrous since it basically means that a knight taking up the quest will never return to his family or his duty as the ruler of his land.
If they don't then can grail knights have children? Is there any indication that they may pass on some of the blessing to their offspring? If so then the brettonian nobility would in time become very different from regular humans.
And also, is Brettonia a hereditary monarchy? or an elective one?
