At the heart of the North Downs, the last remnants of the House of Isildur gather in their hidden refuge of Esteldín. The tides of war crash against the stone walls of their encampment, but they are not yet strong enough to actively resist it and many of their number, including their chieftain Aragorn, still range far afield.
Halbarad, kinsman of Aragorn, struggles to unite the scattered peoples of the North Downs against the hordes of Orcs which have come down from Angmar through Ram Dúath. Like many of the Dúnedain of the North, Halbarad has many qualities of both a warrior and a lore-master. He uses his knowledge to coordinate efforts to hinder the advance of Angmar's army until a stronger front can be established, all the while alert to the knowledge that he may be called to battle and fates unknown in lands far away.
Halbarad appears in J.R.R. Tolkien's The Lord of the Rings as the leader of the Grey Company which joins Aragorn in Rohan and follows him through the Paths of the Dead. He later becomes Aragorn's standard-bearer.
