What is a plot for The Dragon Reborn?

Another blurb extract, if you will:

'The Land is One with the Dragon-and the Dragon is One with the Land.

The Shadow lies across the Pattern of the Age, and the Dark One has turned all his power against the prison that binds him. If it fails he will escape and nothing will stand in the storm that blows then...save the man who was born to battle the darkness:Rand al'Thor, the Dragon Reborn.

But to wage his war Rand must find Callandor, ancient SWord of the Dragon...and the Forsaken will shatter the world to thwart him.'

Just to help, Callandor is a special and very powerful sWord (in a way) that can only be held by the Dragon Reborn, as it is protected by both saidar and saidin shields. Callandor is actually a very strong sa'angreal, which is why it will help Rand apart from being a shimmery sWord.
