Reading the History of the Heortling Peoples. Larnsti are mentioned as neither offering sacrifices to Larnste, nor summoning kolati, nor using sorcery - as I understand, abstaining from the three main forms of magic. "Instead, their very breath knows how to speak the Larnsting words of power." It is also hinted that their Twisting Wind might actually have nothing to do with Orlanth.

Just what is this, in Heroquest rules terms? Are they using some unusual form of theistic magic tied to Larnste and not requiring sacrifices (certainly it seems to be something that they are, and they appear to be forced to imitate their god)? Is it some kind of innate magical talent or some other special form of magic connected to the Movement rune? How would you approach this?
