Thorin's Hall

So Thráin and Thorin with what remained of their following (among whom were Balin and Glóin) returned to Dunland, and soon afterwards they removed and wandered in Eriador, until at last they made a home in exile in the east of the Ered Luin beyond the Lune. Of iron were most of the things that they forged in those days, but they prospered after a fashion, and their numbers slowly increased.
- Appendix A, Durin's Folk

Established as the chief dwelling of Durin's Folk following the loss of Erebor, Thorin's hall is a dwarven settlement in the Ered Luin. It entered a century of prosperity after its namesake, Thorin Oakenshield, became its ruler in T.A. 2845, becoming the largest dwarven settlement west of the Misty Mountains.

After the retaking of Erebor in T.A. 2941, many of Thorin's halls' inhabitants deserted the Ered Luin, choosing to live in the Lonely Mountain instead. This ended its time of prosperity, leaving it a lesser realm of Durin's Folk.
