Destiny definitely needed a way to read lore in game. Be it in ghost files or books you find or mission completion holograms or recordings or WARSAT pods scanned or something, even just having a little storage for each fragment and you give them to Eris who would translate them for you into little green, wispy files your Ghost could pull up. I feel like Destiny tried to do something like what Dark Souls did. Weapons and Armor had little tid bits all scattered about about the world or people or events and all of that. Destiny didn't do it nearly as well as Dark Souls did though...
