Thief’s flexible morals and imperfect knowledge.
The flexible morals move is fascinating to me, because of the implications that it gives all the other players and the GM imperfect knowledge about the thief. I love the idea that either nothing can tell what the thief’s real alignment is, or that the thief just changes their morality to the currently most convenient.
Examples of flexible morals being used in interesting ways:
Paladin “I am dubious of the thief’s motivations. What alignment are they?”
Thief “oh, I’m good of course! You can trust me buddy!”
GM “the cursed bow glows with a ruby malice, only someone truly evil may wield it.”
Thief “I shall bear this burden, it shall not blacken my already black soul.”
GM “the silver angel stands before you at the gates of heaven. It says that only those who carry law in their hearts may enter. Cleric, you’re lawful, right?”
Thief “I’m lawful too, let me pass!”
GM “end of session move! Who met the conditions of their alignment or drive??”
Thief “I recall when I tricked the goblin town into thinking the bard stole their crown, and since my alignment is…. Evil, I’ll take an XP.”
