[Something in his tone relaxes at that, at the idea that there won't be a mass murder happening because of this. The war already makes him feel uneasy, but he didn't want to make a hasty decision without at least making sure they're not sacrificing innocent people for either side.]

Is that even a possible bargain? I don't know how the orbs work, but wouldn't merging them together already be a wish of its own?

[Rather than a price to pay. He doesn't know orbs as well as others, so it feels like a strange idea.]

In any case, I don't know about killing the Highest One... But from the sounds of what you're saying, just helping Entr'i get to where the orb is won't be enough, right? Given that'll just fall under physical possession if we succeed.
