Amazon Prime Video's The Rings of Power delves deep into the First Age of Middle-earth. That said, the history of Arda begins with the Years of the Lamps, Illuin and Ormal, which were created by the Valar to illuminate the world. Melkor wrecks the lamps, forcing his brethren to cultivate Laurelin and Telperion, effectively initiating the Years of the Trees.
