Princess Luna finds herself in many different realities. In some, she is forced to fight terrifying enemies. But ultimately, she succeeds in defeating many of them. As in the world of Terraria, she defeated the terrifying Moon Lord, restored peace to the world, and defeated the imposter who dared to call himself the ruler of the Moon. She now wears Nebula Armor and wields the powerful magical weapons Last Prism and Nebula Arcanum, which greatly enhance her magical attacks. The Last Prism, however, somehow reminds her of the Elements of Harmony. If only they turned enemies into a bloody mess instead of stone.
