RōkaandAnmír were elves of the Tatyar who awoke upon the shores of Cuiviénen. First of their people, they created a fëa-bond together without a simultaneous union of their hröar. Both were resourceful, inventive elves who were among those to the first develop smithing techniques; Rōka made more practical tools, while Anmír was renowned for hir jewelry and soon lengthened hir name to Anmíridil.
The pair was sundered when the Great Journey began, for Anmíridil was enchanted by the promise of Aman while Rōka turned to follow Morwë and the Hwenti eastward. Anmíridil made it to Aman with the rest of the Noldor and became a masterful jewelsmith, named only after Fëanáro Curufinwë in hir skill. In the east, Rōka worked diligently as a maker of weapons, and the work of his hands was vital to the defense of his people; indeed, in one assault of the Dark Vala’s monstrous creatures, Rōka was himself abducted from his home and carried back to Angband, where he was put to work in the mines. Yet he did not go without a fight, and so fierce was his resistance that he earned the name Rôg, “demon,” amid his captivity.
Eventually the Noldor returned to Middle-earth, and Anmíridil was among them. Not long after, Rôg led a rebellion among the thralls of Angband and broke free, escaping to rejoin his long-sundered kin. Thus RôgandAnmíridil found one another again, unlooked for, and rejoiced to be together once more.
WhenRôg was offered a lordship in Prince Turukáno’s hidden city, he asked Anmíridil, now known as Enerdhil in the Grey-elven tongue, to accompany him. Hir heart was moved, and ze accepted, and together they created the House of the Hammer of Wrath. In Gondolin, RôgandEnerdhil would each create many great works, including the King’s sword Glamdring and the restoration of the famous Elessar.
