Around 30 or so years before the events of FF7, a child called Sephiroth was born to two Shin-Ra research scientists, Lucrecia and Hojo. Before he was born, twisted experiments injected the fetus of this child with the cells of a horrible alien. This experiment would loan him great strength, creating a child of amazing potential and power.
This child became a SOLDIER, fighting for Shin-Ra, and eventually helped them win a large war against Wutai. In Nibelheim, he learns of his past in the basement of a research mansion. He goes mad with the knowledge, and sets the city on fire and kills nearly everyone in the Nibelheim (Cloud's hometown).
He eventually attempts to summon a Meteor to injure the planet, and plans to absorb the planet's energy as the planet attempts to heal itself. He is, sadly, foiled by Cloud, and mysteriously disappears, probably into the lifestream.
