Audiobooks of Words of the Faithful and of Slumbered may be added to your reading of these texts, as they are mostly oral histories of ancient days, really. You may also download these files from the Internet Archive: Faithful and Slumbered. I recommend using the Smart AudioBook player.
Second, a collaborative Book of Mormon/Tolkien/Words website is bringing together these different writings, enriching the story.
Many thanks to friends who brought to both projects, their own EA!
And here’s a little map, not to scale.
