In Destiny 2, the final boss of the Root of Nightmares raid is Nezarec. The raid takes place aboard Nezarec’s Pyramid ship, which was transformed by the Traveler’s Light after the events of Lightfall. Guardians battle through the ship’s overgrown, surreal interior before confronting him in the final encounter.
Nezarec is known as the Final God of Pain and was one of the Witness’s Disciples. He had previously been associated with the Lunar Pyramid and the Nightmares that tormented the Moon. Although Nezarec was believed to be dead, the Traveler’s intervention inadvertently restored him, allowing the Guardians to face him again.
A common mix-up is Zo’aurc, Explicator of Planets, who is another major boss in Root of Nightmares but appears before Nezarec. Rhulk belongs to the Vow of the Disciple raid, while Oryx and Taniks are final bosses from different Destiny raids. Root of Nightmares was introduced with Lightfall in March 2023.
