This might be too easy, but we'll see. Who referred to "the only king under the Mountain we have ever known"?
Hi,
The quote "the only king under the Mountain we have ever known" is a reference made by Thorin Oakenshield in J.R.R. Tolkien's "The Hobbit." It reflects Thorin's nostalgia for the former glory of the dwarves and their kingdom under the Lonely Mountain before it was taken by Smaug the dragon. It's a poignant line that speaks to the dwarves' desire to reclaim their homeland.
