After months uprooted, the survivors of the Windrider clan have a home, a new village built under the guidance of Joseph, their human saviour and friend. Alas, peace is not to last as new dangers appear - unknown beasts savaging the woods and rumour of war stirring in the north. If they are to survive, all Joseph's courage and the Windriders' unity will be tested to their limits.

The tale of Joseph, the Spirit of the Trees, concludes in this ultimate clash between old friends and older enemies. Joseph claimed his Identity and joined a Community, but will even these be enough to survive this Calamity?
