Do you ever find yourself with a family member who has so many bad traits that he's just irredeemably 'mad, bad and dangerous to know'? What do you do with a character like this? Sure, you can use him as cheap cavalry in a battle; you can use him as a sentry in some unguarded location; or (with a lot of hard work) you can overcome some of his negative traits and make him into a vaguely useful general or governor. Or here's another idea.

You can send him travelling around all your settlements and generals in the field, siphoning off any 'bad' ancillaries you've collected - i.e. make him into a garbage collector. You could take it a step further: if a 'governor' has an ancillary that's of more use to a general (or vice versa), let the family member in question 'collect' that ancillary and deliver it to where it'll be of more use - the travelling salesman.

I'm sure I'm not the first to think of this, but as I haven't seen it mentioned elsewhere and think it's a useful idea - well, there it is.

P.S. I've also edited it into my Treatise.
