Thrór

Thrór (2542 TA-2790 TA) was a King of Durin's folk, the son of Dáin I and the father of Thráin II, and brother to Frór and Grór. In 2790 he journeyed with Nár to Moria, upon entering it, he was killed by Azog the Goblin, which started the War of the Dwarves and Orcs.
 * Thrór was the first King who lived in exile: after a cold-drake had killed Dáin I and Frór, only a part of Durin's folk joined him in the mines of Erebor, the greater part moving to the Iron Hills under Grór (see also Encyclopedia of Arda: Thrór).
