The tree spirits gave Herath wooden hand until he does what they want. We established that. We didn’t establish, however, what exactly they wanted.
My instinct here is to come up with an idea for what they want, then introduce it as a soft move (“Reveal an unwelcome truth”) when it’s possible to act on it. If I come up with some other idea in the mean time, and see a situation where it’s possible to act on that, I may use that idea instead and discard my original one.
But do you have any other suggestions for how to do this?
