Looking back through these forums I saw a post asking who Eris was and showing a pic of her icon screenshot from the Companion UI (I don't know how s/he accessed it.), while I immediately recalled Eris being a new Event Vendor in The Dark Below I also immediately recognized the icon she bears. It's remarkably similar to that seen on the right inner-cover of the worn leather-bound book containing the Arms and Armament Guide. If you look at Crota's Emblem (marked by the Flame stemming from his sword in the ground at his feet), you'll notice it's similar to the first emblem presented in the same location, adding two points and elaborating on the design to better fit the Hive culture. There's also quite a lot of lore in the Guide as I'm sure you've noticed by now, it's the only place you can see Andal Brask (the Hunter Vanguard who wagered the bet with Cayde-6, he later passed away and the bet was honored reluctantly (but luckily) by Cayde. As well as notes about the properties of Light, theories as to it's source, some tidbits about the Vex, some charts about how Warlock force pulses emanate from their hands, and even size charts that put a typical human to scale to our enemies. (Also of note, some insight to how the Class' mindsets and appearance choices are based around lie within the pages between 52-69, and the notes written all around the guide before-after also provide some interesting quotables.) I also went ahead and translated Post Proelia Praemia via Google; "After the Battle, Rewards", upon which someone noted "There is no After." EDIT: on the Starchart there are also various charts about Light, and in the Thank You note I quote [quote]Add your Light to theirs. Bring it to the Black Heart of our enemies. For the union between the Past and the Present begins now.[/quote] Right off the bat they forewarned you against the Vex! The Heart of the Black Garden and Atheon.
