The final artifact was said to be hidden within the treacherous Temple of Shadows, a place of unspeakable darkness. Mr. E, Harumi, and the ninja arrived at the temple, ready to confront whatever awaited them. But it was here that a shocking revelation unfolded.

Harumi had been secretly communicating with Lord Garmadon all along. She had been feeding him information about their progress and the locations of the artifacts. In return, Garmadon promised to spare her village, Birchwood Forest, from his wrath.

Mr. E felt a profound sense of betrayal. He had believed in Harumi's desire for redemption, and now he saw that she was willing to sacrifice their mission and the safety of Ninjago for the sake of her village.
