Oh.
Ohhhh.
Lord Nethys does have some secret plan that involves His intricate understanding of every move that lesser beings make, thinking their choices their own.
Going to fantastic lengths to make sure Keltham can get five books a day faster than Security could order them from Chelish libraries... doesn't make that much sense as the sole object of an expensive divine intervention, so Ione had supposed that she was going to be there to influence Keltham in a subtle way, or maybe see something that Asmodeans wouldn't see because they're too busy gouging each other's eyes out.
"If you get Keltham to flee to a remote wilderness hideout, or some old dungeon that's blocked from scrying, he's not going to get much research done unless he has a library oracle with him," Ione observes. "Keltham knows that. He'll come to me early on. Though I'll need enough books to turn some room wherever I go, into a library... I think one full bookshelf should do it, but two would be better." She wants to ask, rather acerbically, if any Asmodean even noticed that their plan wouldn't work without Lord Nethys propping it up, but she is not quite that courageous yet.
