According to mythology mankind used to live in The Tranquiline Halls.
Led by ten angelic Heralds and ten orders of knights known as Radiants, mankind finally won..
To help them cope, the Almighty gave men powerful suits of armor and mystical weapons, known as Shardblades.
They came against man ten thousand times.
And the Voidbringers followed ...
Men took root on Roshar, the world of storms.
But then the Voidbringers assaulted and captured heaven, casting out God and men.
Heaven.
