Substitution Cipher Puzzle

This line comes from the poem "All That is Gold Does Not Glitter" in J.R.R. Tolkien's "The Fellowship of the Ring," published in 1954. The poem is written about Aragorn, the ranger who is secretly the heir to the throne of Gondor, and it speaks to the idea that appearances can be deceiving and that purpose is not always visible to outsiders.

The verse has taken on a life far beyond its literary origins, becoming one of the most quoted lines in modern culture. It resonates with travelers, adventurers, and anyone who has chosen an unconventional path. Tolkien himself was deeply influenced by his love of languages, mythology, and the English countryside, themes of wandering and discovery that permeate his entire legendarium.
