Nibelheim is comprised of five accessible buildings and the mansion at the end. There is also a route next to the mansion which exits Nibelheim and leads up to Mt. Nibel. There are two times the player enters Nibelheim during the story and takes full control of where they go. The first time is Cloud and Sephiroth during the flashback told at Kalm before Nibelheim was razed, and the second time is with the party is in the restored Nibelheim.
