Thrór

Thrór (Third Age 2542 – 2790, lived 248 years) was King of Durin's folk for 201 years, from 2589 to 2790. He was the eldest son of Dáin I, and with his younger brother Grór he led his people away from the Grey Mountains after a cold-drake killed both his father and brother Frór. Thrór led some of the Dwarves back to Lonely Mountain, where he became King under the Mountain. Grór continued west with the rest of Durin's folk until he reached the Iron Hills, where he founded his own kingdom.

In 2770 the dragon Smaug attacked and sacked Lonely Mountain. Thrór and other dwarves managed to escape through the hidden Side Door. Despondent and homeless, he left his people and went south with a single companion, Nár, but not before giving his son Thráin II his Ring of Power, along with the map and key to Lonely Mountain. Thrór wished to see the fabled city of his ancestors, Khazad-dûm, and ignored Nár's warnings that it had become the "Black Pit" of Moria. However, at Moria Thrór was captured and butchered by Azog the Goblin King, who carved his own name on Thrór's severed head in Dwarvish runes.

Nár was released by Azog so that all Dwarves would know that an Orc now ruled Moria. Nár told King Thráin II of the abomination, which began the War of the Dwarves and Orcs.
