The Second Age spans 3441 years and ends with the first downfall of Sauron, the primary antagonist of “The Lord of the Rings.” Jackson’s movies begin with a prologue set at the end of the Second Age explaining Sauron’s defeat, so it would appear Amazon’s series will take place in the years where Sauron rises to power. Events in the Second Age that the series could focus on include Sauron building his forces in Mordor, the creation and distribution of the rings of power, and the destruction of Númenor. Considering the island’s appearance on the map and its legacy within Tolkien’s world, it appears likely the series will have much to do with Númenor.
Sounds great to me! Just keep Peter Jackson away.
