If he had examples then he would know how anything worked and he would be less nervous!
Keltham's actual direct experience here consists of himself getting an Owl's Wisdom, and realizing that his previous life plans within dath ilan were entirely hopeless and in fact he had enough data to realize this and was lying to himself about it. Good thing he was in Golarion first!
And then there's Asmodia, who got an artifact headband put on herself, invented a lot of Law and wound up relating to it in a specifically Keeper-like fashion which has effects that people like Keltham deliberately don't get told about. Keltham does not, among other things, know whether or not it's possible for Keepers to fall in love. For example. Keltham initially thought this was probably because Keepers couldn't, and you don't want to tell all the nonKeepers who are in love that their love is unLawful; but on reflection it's much more likely that the Keepers have some well-phrased blanket policy of hiding everything that might be like that from the perspective of nonKeepers, so that their pattern of secrets doesn't leak information.
