Gandalf reading in the Book of Marzabul in Moria, at the beginning of chapter V "The Bridge of Khazâd-dûm" (in Book Two in "Fellowship) about the final days of Balin's ill-fated expedition to re-settle Moria.What's the Tolkien reference for this? I'm sure there's one...
Edit: I guess I type too slowly ... 😒
