Miffli was born while the clan traversed a steep ridge in the Misty Mountains. He grew up among the peaks, cliffs, and caverns there, conquering unclimbed summits, exploring i mysterious boulder fields, and crawling through tunnels frequented by Goblins. He was bolder than the typical Ibûnite , and more curious. How much hidden knowledge he uncovered in the heights and depths of the mountains is open to speculation, but it is certain that he came in time to possess a ring of great magical powers. When he came of age, Miffli led his clan to the twisted hill of Cameth Brin and found the entrance to the caverns lacing its haunted stone. The Ibûnites labored long to delve the halls they called Armoq-al-Wanu, but their numbers were few. Settled at last in a home of their choosing, they died, one by one. But Miffli lived on, far past the lifespan natural to his kind. His ring granted him immortality — at a price. Although undying, Miffli did not cease to age. His libs grew evermore withered, his hair thinner, and his voice more cracked. Tales and legends suggest different origins for his ring; one recounts Miffli's heroic efforts at a forge long forgotten by the Khazad, another tells of bis challenge to the Dragon Angurth, and yet a third suggests that Sauron may have hidden beneath Cameth Brin during the centuries after the War of Wrath which ended the Elder Days. Whatever the truth, Mifflis ring preserved the Ibûnite through the ages and gave him the power to command the undead spirits of his former companions, renamed Ta-Fa-Lish by the Hillmen. In the spring of T.A, 164, Miffli aided the Hillman Mongán Finn in a rebellion against the Dúnedain, Eldacar of Arnor, the Crown Prince of Arnor, crushed the Hillmen and took Cameth Brin to be a royal fortress. Homeless and severed from the ghosts of his clan, Miffli survived the conflict to wander across Middle-Earth once more.
