That's... not what I meant. I meant something that establishes the world and the characters more... "clearly" and not just dropping us in. I guess I mean like a tutorial, not to explain the gameplay, but to how the world works.
I'm not sure that's really necessary. Don't you have all that information by the end of chapter 1 anyway, or chapter 2 at the latest? Plus you don't want to dump all the lore on someone at once, since that breaks immersion and is often overwhelming.
