Phantasy Star 0 Story

Once, there was prosperity.
Three tribes thrived of old, and gave birth to Divinity.
Then, there was war.
The rift between god and mortal cut through the tribes like a blade.
Then there was desolation.
A vast emptiness, and nothing more.
Two centuries went by...
People survived, and pushed back against the edge of oblivion.
Until today...
In the middle of a bright sky, a shadow covered the moon...
and the forgotten ones swooped down from the heavens.
