Most of the villagers have embraced the Kindred and all that they have to teach, but there are those who fear the Kindreds' influence, and so have drifted away to live as outcasts.

Only then will he fully understand the lengths to which Amarilla and Infinity have gone to ensure that he can fulfil his destiny and reunite the human race...
