The Silmarillion: Tales of the 1st Age

Beleriand in the First Age — the dark dominion of Morgoth, the elven realms of Hithlum, Gondolin, Nargothrond and Doriath, and the long shadow that fell over them before the Fall of the Hidden City. Wander the wars of Beleriand, from the frozen wastes of Angband to the green havens by the Sundering Sea.
