This, the first part especially, is one of the biggest flaws in the game. The game expects players to read through tons of dry text to find out what is actually going on, instead of showing it to you in a game-y way.
While you can get by without understanding most of the second part, the world is simply just boring if you don't.
As most people probably know by now, I am far from a fan of these games, but even I will admit that the trilogy has some pretty interesting lore. What ticks me off is just that the game is so horrendously bad at presenting said lore to the player in an interesting way (if at all). It could have been as easy as overhearing a child asking her mother to tell her what a falcie is, or where the world came from.
