Third Age 2850
From Tolkien Gateway
Notable events in this year include:
- Gandalf again enters Dol Guldur, and discovers that its master is indeed Sauron, who is gathering all the Rings and seeking for news of the One, and of Isildur's Heir. He finds King Thráin II and receives the key of Erebor, but doesn't know who the Dwarf was as he had forgotten his own name.
- Death of King Thráin II in Dol Guldur. Loss of the Ring of Thrór.
- Around that time Thorin II Oakenshield, son of Thráin II, becomes the King of Durin's Folk.[note 1] </ref>
- It is unclear when Thorin succeeded his father as King, after his disappearance; Thráin was abducted in T.A. 2845 and presumably his companions reported it soon after. Thráin died in capture five years later in 2850 but nobody knew it, as it was Gandalf the only one to witness it, and didn't know who he was. According to Appendix A, it was only in 91 years later, meeting Thorin, when he realised that the captured Dwarf he saw dying in Dol Guldur was Thráin, and presumably (not mentioned in the narrative) he reported it to Thorin. It is hard to believe that the Longbeards knew when their King died, or that they remained kingless almost a century until Gandalf confirmed it to Thorin; it is reasonable that Thorin succeeded his father not too long after his disappearance.
