The Dúnedain were the descendants of Númenor, an ancient bloodline of royalty and long life. After the fall of Arnor, these Heirs of Isildur went into hiding, often growing up in Rivendell and spending time in the company of elves. The Dúnedain remained in their self-imposed exile until Aragorn II, son of Arathorn II, reclaimed the crown of Gondor after the War of the Ring.
In Edain Mod, the Dunedain are a sub-faction of Imladris and can be found at the special Outpost expansion, the Dunedain Outpost. Halbarad, Dunedain Swordsmen, Spearmen, Archers and battering rams can all be recruited here.
