I still think that the quick answer Greg gave me years ago on what a
worshiper had to do is one of the best answers to most most of these sorts
of questions. (Basically the question was something along the lines of
which of several intretations was the "correct" one.)
The rough answer was 'To worship Humakt you have to be willing to kill and
willing to die. That is what Humakt requires. The rest is cultural.'
