I believe the Seneschal would benefit marvelously from something which would provide some small source of distraction. Nothing too complicated or consuming mind you, but perhaps a little game or something like it. Something he might pick up and put down easily - one of those little puzzles which are good for living on a desk or in a drawer. You know the sort of thing.

But I'm certain whatever Bastien suggested would also be quite nice. Only you must promise not to get him a cushion for his chair! I've stolen the rights to that one already.
