Heroes of the Northern Lands
After the fall of the Northern Kingdon of Arnor, few remnants of the Dunedain were left to guard it.
After suffering a great loss of men, as Elendil lead their armies to battle against Sauron at the Battle of the Last Alliance, the northern Kingdom of Arnor, fell prey to more catastrophe.
As no king returned to claim lordship, the kingdom broke down into three factions; Arthedain, Cardolan and Rhurdaur. These territories fought each other in civil war to contest the right to rule.
And so it was the kingdom was further weakened... and became ripe for conquest by the armies of the Witch King of Angmar.
To finally seal their doom, a great plague swept the lands, which left virtually none left to populate the lands. The Northern Kingdom was destroyed... but for a handful of survivors, succored by Elrond of Rivendell. Here in Imladris the line of kings was maintained through the centuries...
Arathorn, actually Arathorn II, father of Aragorn. He was slain fighting trolls and orcs, with the Rangers of Arnor in Eriador, when Aragorn was only two years old.
Halbarad, Dunedain, Captain of Rangers and the Grey Company, at the time of the War of the Ring.
Halbarad, bearing the banner of Arwen Evenstar.
Elladan and Elrohir, sons of Elrond of Rivendell, and brothers to Arwen. They fought ever to defend the lands around Rivendell, and joined the Grey Company of rangers that joined with Aragorn and the forces of Rohan, arriving after the Battle of Helms Deep. They and the Grey Company traveled with Aragorn, Gimli and Legolas, through the Dimholt, and joined with the Armies of the Dead, defeated the Corsairs of Umbar and used their ships to arrive in the nick of time at the Battle of the Pelenor Field, and saved Minas Tirith from downfall.
