There Is something, a PDF or similari, where there Is the more of the Human Sphere? I mean: inwould like tonerad the history of the world, how the faction was generated and now the formed. The more of the faction and so on. There Is something like that?
There is no electronic version of the lore, that's the deal: the rules are free, you have to buy the lore as a hardcopy. The only alternative that lets you see the lore in electronic version would be the RPG, which has books for each main faction; however, YMWV, as personally I found little interest in reading the day-to-day lives in the Human Sphere. By the way, just in case of someone from CB comes along this thread, I really wished they would publish the lore in PDF for N4. Yes, PDFs can end up being shared, but at some point, put some trust in your players.
If you want lore in good and easy to digest quantities, the Modiphius RPG books are cheap enough to purchase and you get a lot of stuff for what you pay for them. I seriously recommend those.
Wich one? i found the shop online and as far i can see there are the core book, one fo each faction, the core book, the player book.
Core book is a good start, it's got oodles of info. If you want more on a specific faction you can get that faction's book as well.
As someone who own all the RPG books that are so far released for stores, they are treasure troves of lore information. Even the various adventure books contain a lot of little bits of lore. The core book will be plenty for a surface check on each factions and the world at large though. You'll get info on the history of each faction, their territories and how they work.
Yeah, the RPG books are your best bet for details not included in the fluffbooks, which are hard-copy only.
