Secret GM Info for Hassan

The book (your grimoire) has no specific provisions for behavior.

The passage that comes the closest says:

"Magic is at best a subversion of the natural order of things, an intrusion of chaos into the regular. Feats accomplished by such power are indeed formidable, but not prone to last. While wind can indeed be diverted, it eventually resumes its course. To permanently alter the flow of wind, or the native progress of any given thing, is something difficult and not easily done.

"It follows, then, that development of tools to deal with the actors of the world, on their own stage, is something valuable. A lie told convincingly can hold a mind in thrall. The victim will become worried of his own judgement, and will spend considerable effort in justifying action taken upon that lie, until that lie becomes, for all intents, a truth to the victim. A lie told by twisting the grey wind will be perhaps more effective in the immediate term, but such a thing is unnatural, and the victim's mind will simply forget. Each lie has its place, but do not underestimate the value of the former."
