“There was Eru, the One, who in Arda is called Ilúvatar” - this is how J. R. R. Tolkien’s famous book “The Silmarillion” begins.

But are the winners really right and were the vanquished such terrible villains? The Black Book of Arda tells about this - a look from the other side at the well-known world of Tolkien.
