Look back many years to the West of Middle Earth, to the misty, dim shores. See it now. See it very well. See The Blades of Arnor answering the call to arms. In the dim and distant past, before history ran into legacy and before the Light Knights were born, The Blades of Arnor gathered their kin together to defend Middle Earth. After many adventures, The Blades formed an alliance with another ancient kin in Middle Earth, The Guardians of Annuminas. Battles were fought together, blood was shed, and victory was taken. From the ashes of this alliance, The Blades became the official LOTRO kinship under the Light Knights gaming community.
The Blades of Arnor are the descendents of the honour guard of Eärendur, the last king of ancient Arnor. When Arnor collapsed into civil war following Eärendur's death in III 861 the Blades sided with his eldest son at his capital of Fornost in the newly founded kingdom of Arthedain, although their loyalty to the idea of Arnor remained undiminished.
As Arnor's greatness slipped into history a new and dark power rose in the north-east: Angmar, led by the chief of Sauron's Nazgûl himself. The Witch King preyed on the old emnities between Arthedain, Rhudaur and Cardolan, the three successor kingdoms of Arnor, and eventually he brought sword and flame to all of them.
After centuries of bitter war and treachery, the final battle against Angmar was fought at Fornost. Strengthened by forces from Gondor and elves from Lindon and Rivendell, the remnants of Arthedain's armies broke Angmar and pushed the Witch King out of Eriador and back to Mordor, far to the south. The victory, however, was too late to save the dream of Arnor. Arthedain, the last hope for a united kingdom in the north, was utterly destroyed.
In the centuries since then the Blades of Arnor have remained as a secret society spread across the whole of Middle-earth, watching and preparing for the next war with the Witch King and his master Sauron. Their membership has been handed down from father to son and their numbers maintained by recruiting others loyal to their cause. Men, elves, dwarves and even humble halflings from the Shire all now muster under the banner of ancient Arnor, waiting for Isildur's Heir to return to rebuild the great northern kingdom and its capital of Annúminas.
And now, two thousand years after the final destruction of Arnor, the icy claw of the Witch King of Angmar once more stretches across Eriador. Orcs, goblins and other fell creatures issue from Carn Dûm intent on spreading death and destruction at the behest of their foul master and, through him, of Sauron himself. Once more the ancient lands of Arnor are under siege.
The call to arms is sounded! And again the Blades of Arnor answer.
