Pillaging his way through the realms of his daughter's liberators, Halldor banishes his kin and has the brothers driven from their land.

But new challenges await on this island, and new discoveries must be made if they are to survive. Will the brothers be able to stand together and offer a better future for all the settlers, or will this new mission divide them even more ...
