Jenova

Jenova Jenova is a calamity from the skies, she is an alien life force that travels from planet to planet destroying them. Jenova was mistaken for a Cetra because of her vast powers when she was excavated by ShinRa. The scientist Hojo and Gast ran experiments and studies upon her. The documents on Jenova can actually be found in the Shinra Mansion in Nibelheim.

Jenova's cells along with mako are injected into SOLDIER members. This is probably due to the fact that she was mistaken as a Cetra and ShinRa wanted their fighting force to have the upper hand.

Another part of the project involved lying to a child after he was born. Telling him the his mother was a woman named Jenova and that she died it childbirth. This was probably to hide and cover up Lucrecia, so she could never claim her child.

And the baby

SephirothThis is the project in which Lucrecia Crescent consented to injecting her unborn baby with Jenova cells and mako. While she was pregnant with Sephiroth (that’s the baby’s name) she had visions of what the child was going to do and they were horrible. However, the Jenova cells in her body would not let her die. She gave birth to her son and not once did she ever get to hold him. Sephiroth grew up without ever knowing of his mother Lucrecia Crescent and was told his mother was Jenova and that she died in child birth. Lucrecia, filled with such guilt disappeared and incased herself in a mako tomb unable to die.
