The Darkening of Valinor was an event that occurred at the end of the Years of the Trees. This event in particular refers to the killing of the two trees, Telperion and Laurelin, by Melkor and Ungoliant. This event ultimately included the murder of Finwë, High King of the Ñoldor, at Formenos, the stronghold of Feanor, and the theft of the Silmarils. This all brought about the exile of the Noldorin elves from Valinor, the first risings of the sun and moon, and the Awakening of Men in Middle-earth at Hildórien. It was during this time that Melkor was named Morgoth by Feanor and escaped to his stronghold at Angband, where he would remain for the remainder of the First Age.
