"...should I assume that it would be prohibitively expensive to confirm more exactly?"

This also seems to be puzzling to the Shadow-Lover.

“You have crossed paths with this soul. …You saw a path through the darkness, that was narrow but could have been walked. It could have been wider, if - it was information We could have given.”

"It sounds like you mean Leareth and I will operate under that assumption unless corrected."

The Shadow-Lover does not provide any correction.

“There are other paths, if you are here, but We cannot see so far to steer.”

"Paths to what?"

Another moment of distant translation - the sense that the Shadow-Lover is searching Blai for some way to cross a communication gulf.

“To change the game.” 

"Iomedae is having a difficult year but I believe Her reputed ability to make herself well-understood in visions is just a property of Her having once been human. You could try talking to Cayden Cailean and see if He has any advice for You."

A nod.

“Is there a message you would pass to your goddess, if no price were asked of Her for it?”

"...it's not expensive in that direction, I tell Her things all the time, the expensive thing is Her talking to mortals."

“Interesting. It is different here.”

"Is there something You would like to know as long as I'm here?"

Another strange thoughtful pause.

“What do you steer for?” the avatar of a god says to him.

"...I steer for Iomedae's values as I understand them. Law, Good, peace, prosperity, the efficient application of resources toward these aims, the establishment of precedents and institutions that will cultivate them going forward."

Puzzled. “What is Law?”

"Law is about making and keeping commitments. It has many possible implementations but Iomedae's focuses on honesty, trustworthiness, the possibility of cooperation, abiding by promises and treaties and using that reliability to be more appealing to treat with at all. ...If you're using prophecy to see, it would probably look like things that certain people cannot be steered into or at least are unusually difficult to steer into, especially if those tendencies arise at a specific point in their lives when they make a decision as opposed to arising over time as they develop a preference."

It’s unclear how well the Shadow-Lover is following but they certainly seem to be listening intently.

“The immortal one. Who you called Leareth. Is - the way he cannot be steered - the thing that is Law?”

"- maybe! He is Lawful, I checked that."

“He is very strange. He wishes to change the rules of the game, and this is frightening.” 

Another pause. “The others would prefer that were not in the world. But We can play a different game, if that is a path that can be followed. That is what you can tell him, if you wish.”

A hint of frustration, or something like it but more alien. “There is more information that is relevant to his choice. We cannot say it to you, only to him, if he were to come for a time into the shadows. It is - difficult to say things to mortals.” 

"I... do not think he will want to do that. Why is it that you can say it to him but not to me?"

The Shadow-Lover seems to spend a long time considering this. Considering Blai, as though examining him from a dozen strange angles.

Effortfully:

“We see the effect on you. That is what information does, it has an effect. But there is information in him that is not in you to be seen, and so We cannot see what to say if it is to be said to him.”

"Would it help if I promise to relay it as exactly as possible to - mimic a direct missive?"

“Maybe. If you wish to try.”

Another pause.

“We cannot see what he steers for, but - if it is the other world, We steer for that as well. That is information he should have.”

"I'll tell him."

“We cannot see what effect that will have, but - if he sees more then it will be good.”

The sense of a smile behind the shadow. “You have the information you need. You can rest here, if you wish, that is something this place offers that can have effects.”

"Thank you."

It's nice here. Thoughts rain through his mind and none of them are acid. Just him and a small woman who is also a god who is having a hard time learning to talk.

"And thank you for Seldan."
