Book of Cain discussion (Book/Game Spoilers) Howdy. Figured we could make a thread dedicated to talking about the book of cain because holy crap is it extensive. It seems to me like this book wasn't intended to be released so far ahead of the game, as if they actually believed the 2011 release date window themselves. As a warning, this post is also going to contain speculation based upon information that I datamined in the beta client's numerous patches, but these portions will be under spoiler tags. Feel free to talk about anything in the book, though. I've just started reading it, as I have been playing/gathering info for the wiki/working, but the introductory letter to Leah is very interesting all on its own. Some quotes I'm referencing: So...begin spoilers: Spoiler Ok. A few quotes are pulled to display the time that Cain is writing this: during the game. He likely wrote this letter while the player is off in Wortham, or around there. The book itself, no, but the letter to Leah, the prologue, certainly. Cain makes numerous references in the letter of his own death. It's pretty much sure that he's going to die in Act I, probably not horribly long after the beta ends. This is after the player finds "the Stranger" and brings him to Deckard Cain. This provides even more confirmation that the stranger is Tyrael, but now Cain mentions a sacrifice he had to make. Tyrael appears to be a black human in the game, similar in appearance to the paladin from D2, actually. But all we've seen of him so far is his icon, just his face. One he is armored, one he is unarmored. A question worth asking is why the presence of Tyrael is "corrupting" the land by re-awakening the "evils" such as the skeleton king and all that. A shard of his sword lands inside of the Drowned Temple, which is filled with Nephalem ghosts re-enacting their final battle in a continuous cycle. The ghosts were awakened by the piece of the blade and the nephalem ghost you gives you the quest--Alaric--he is not happy about this. Next is Leah. So she's had prophetic dreams, much like in the black soulstone cinematic, but Cain says they are not a certain future. The Prophecy: Angel - their aspect (what was said about them in the prophecy) Auriel - Hope (will be swallowed by despair) Imperius - Valor (shall turn to wrath) Ithereal - Fate (lies shattered forever) Malthael - Wisdom (shall be lost) Tyrael - Justice (falls upon the world of men --the fallen star) Not sounding too good for the Angiris Council. This is going to be extra-spoilery: In the game files, there's a lot of references to fallen angel mobs that you'll be fighting, fountains of corruption that you interact with, and "Diablo's" goal is to corrupt the high heavens. Rakanoth is the Demon Lord of Anguish. Wrath sure sounds like a demon lord. So in this scenario (set forth by the prophecy) heaven is not just being invaded--it's being obliterated. Angels are falling, Izual returns, archangels are being corrupted like Izual was. There's an event with Imperius outside of the diamond gates, the entrance to Heaven. Tyrael is there, too. I'm thinking that Imperius falls, maybe by someone using the black soulstone or something, and turns to "wrath". And there's a choice that the player has to make near the end of the game. There's an item modifier that increases your "corruption" rating. So maybe it's you who decides the fate of the high heavens. But there's a lot unanswered here. Keeping the "choice" the player has to make in mind, it's curious that Cain mentions that he sees Leah standing between the light and the darkness, and there's a "corrupted" version of Leah in the game files as well. I was gonna keep this short but I guess that flew out the window.
