King of Durin's exiled Folk for sixty years (T.A, 2790-2850), Thrain II led the Dwarves against the Orcs and Wargs in their War (in T.A. 2793-99); he lost an eye at the fateful Battle of Azanulbizar. Driven by greed and alust for power, Thrain II left the Blue Mountains with his followers in T.A. 2841, heading for the Lonely Mountain. In 2845, after years of inconclusive wandering, the valiant but vain King was seized by Orcs in Mirkwood and imprisoned in Dol Guldur. His Dwarven Ring of Power was taken away, the last of the Seven Rings, and he himself was tortured for five years, but Thrain II heroically managed to give the Key to Erebor and a map of the Lonely Mountain to Gandalf before his death in T.A. 2850. The son of Thror, he fathered Thorin Oakenshield, Frerin and Dis.
