Part 4/8:

Despite his failures, Auli's contributions to the world of Arda are monumental. Long before the First Age, when the original spirits descended into the world, Auli took it upon himself to combat the all-encompassing darkness. At the request of his wife, Yavanna, he created two powerful lamps designed to illuminate Middle-earth. These lamps, located in the north and south, lit the land for millennia until Melkor shattered them, plunging the world back into darkness.

Auli was also responsible for constructing Angainor, an unbreakable chain that held Melkor, the mightiest of the Valar, captive in Mandos’ halls for three millennia. This act further solidifies Auli's role as a bulwark of order against chaos.
