Final Fantasy 7 Sephiroth Learns of Genova

Cloud tells the team of his time in Soldier, and we take part in a flashback to his mission with Sephiroth to Nibelheim. During which, we see the events of the Nibelheim Incident, where Sephiroth, Cloud, and Tifa find a Mako Fountain, before exploring the Mako Reactor up on the mountain. There, the group finds Jenova, as well as the makonoids created inside the reactor. The following day, Sephiroth heads to the Shinra Mansion in town, where he reads about the experiments leading to his own creation, and in his rage, destroys the town of Nibelheim, believing he was a Cetra, and that he was taking revenge on the humans that had turned against his "mother."
