Leareth keeps his face carefully neutral. He's still mulling over the pharaoh's apparent reasons for not demanding answers from Fazil 'Part of what the essence of Law is is being the kind of person other people can successfully cooperate with, not just when it's momentarily advantageous but all the time, and he's glad we came to him and prefers to predictably be someone we're glad we came to.'
...It makes him feel significantly more inclined to cooperate with the man, actually. And maybe with the god. Unclear to what extent those are a package deal.
"Then I suppose we wait for his answer," he says, "and I will talk to his magical researchers. And - consider telling him the full story. I am more inclined to trust him now than I was merely on priors."
Mostly, at this point, he wants to spend some time mulling over how to explain it, which pieces in what order. Probably he shouldn't open with an argument about slaves and economic efficiency even though it's tempting; he really ought to regain access to Velgarth and get some of his old treatises first. The pharaoh is supposedly very good at winning arguments and Leareth can believe it.
"I would like to check back with my organization in Velgarth at some point," he adds. "I suppose I could Gate back, or ask about a crystal ball here."
