Main Story
Nightbringer is first mentioned in Lesson 8-16 (of Obey Me! Nightbringer!) by a human named Adam who possessed Mammon's body. Adam was searching for his lost love in the Devildom. But, he became lost in the darkness as the Devildom wasn't a place meant for humans. Adam ended up wandering around lost for a long time. For a while, he was unable to see or hear anything until he heard the sound of a trumpet one day. After the trumpet stopped playing, Nightbringer appeared in front of him. Adam begged Nightbringer to help him find his lost love, but Nightbringer replied that he was unable to do anything for Adam right now. But, he promised that there would be a person who would one day appear and be able to help him. Nightbringer then offered to bring Adam to the place where he would one day meet that person and Adam accepted his offer. He told Adam that this person would possess the ring of light that could open the gates of the Celestial Realm which would help him reunite with his lost love.

In Lesson 8-18, Adam states that Nightbringer left a message with him for MC stating that it wasn't time for them to return just yet. In Lesson 9-2, Solomon and MC speculated about whether the person who sent MC to the past was actually Nightbringer since he left them that message.
