Boromir, Steward of Gondor (ancestor of the Boromir of the Fellowship of the Ring), seeks to dispossess the absent House of Elendil of their claim on the crown of Gondor, and take it for himself and the House of Hurin.

Sauron assassinates Ar-Pharazôn before the Great Armament can be sent against Valinor, and takes power as Steward, turning the military might of Numenor and Mordor against the Eldar and Faithful; the history of Arda is altered forever.
