they will expand on it in the sense that they will show the children of the forest creating the white walkers, who are a weapon to destroy the first men. we already know all of that. the reason they didn't expand on who the night king is? because there is no night king in the books, they just made him up for there to be a big bad villain because we like something simple and easy to digest like that in our content slop. the only 'night king' in the books was just some asshole like craster.
