Also, since I'm about halfway through TDTCB, my 3rd reread. I've seen a couple things early that point to Seswatha being a bigger part of this story. First, I believe right of the bat Seswatha is starting to manipulate Akka's dreams. He notes in one of his first dreams we see that when he looks in the mirror he see's himself and not Seswatha, notes how odd that is. Secondly, when he's meeting with Inrau and Sarcellus knocks him to the ground he whispers in Akka's ear, "Oh, how I've longed to do that!". Right there is a skin spy speaking to Seswatha and you would never pick that up unless on a reread. And, it enforces the idea, to me, that Seswatha is part of this thing hands on. It actually shocked me when I read it, like a subtle clue left so early on.
Ime pretty sure every Skin-Spy has spoken to Seswatha thru the Mandati. Chigra Almost as if instead of seeing the mark the Skin-spys see him
Right, they always do. Just this instance none of that is explained as of yet. And what it said to me is that they've (skins spies) have been waging this war with the Mandate (Seswatha) since they've been around. Seswatha is their true enemy, not Akka or any other Mandate Schoolmen. And, like I was saying, upon first read you would think Sarcellus is just speaking to Akka. He's not though, he's saying that to Chigra (Seswatha). Almost as if Akka meant nothing to him, he was just so satisfied to smack Seswatha.
