how do i get the quest to go to night fall?

sorry im a newbie i'd just starting to replay this game and i want to access night fall. i cant seem to find the quest that allows me to night fall. i dont have the expansion pack of night fall either. if anyone knows this plz reply. thank you.

Well to get their you are first going to have to buy the Nightfall expansion pack. If you don't have that expansion on your account you can not access any parts of Nightfall. Buy that first. Once you do this to get to NF from Prophecies do this quest:
