J.R.R. Tolkien famously described the Second Age of Middle-earth as a ‘dark age, and not very much of its history is (or need be) told’. And for many years readers would need to be content with the tantalizing glimpses of it found within the pages of The Lord of the Rings and its appendices, including the forging of the Rings of Power, the building of the Barad-dûr and the rise of Sauron.

It was not until Christopher Tolkien published The Silmarillion after his father’s death that a fuller story could be told. Although much of the book’s content concerned the First Age of Middle-earth, there were at its close two key works that revealed the tumultuous events concerning the rise and fall of the island of Númenor. Raised out of the Great Sea and gifted to the Men of Middle-earth as a reward for aiding the angelic Valar and the Elves in the defeat and capture of the Dark Lord Morgoth, the kingdom became a seat of influence and wealth; but as the Númenóreans’ power increased, the seed of their downfall would inevitably be sown, culminating in the Last Alliance of Elves and Men.
