This passage from page 16 of U&WA confuses me:
Clerics will require passersby to give a tithe (10%) of all their money and jewels. If there is no payment possible the Cleric will send the adventurers on some form of Lawful or Chaotic task, under Quest. Generally Evil High Priests will simple [sic] slay Lawful or Neutral passersby who fail to pay their tithes.
This passage could be read in a number of ways. I find the most likely reading is that lawful clerics assign Lawful quests to lawful or neutral indigents, while chaotic clerics (EHP's) assign Chaotic quests to chaotic passersby and kill those of other alignments.
That leaves unanswered the question of what lawful clerics do with chaotic passersby who are unable to pay. Any guesses? Or is there a better reading of the text?
