As she wrote, a green glow appeared above her head. Luna looked up, curious, and watched as a helmet materialized in the glow and dropped down on her head. The helmet covered her entire head and face, and the eyesockets began to glow a bright green.
Luna immediately tried to resist and take the helmet off, but it was as if it was welded to her head. She could feel powerful mind control magic seeping into her mind, and despite her best efforts, she was unable to fight it off.
Her eyes began to glow green inside the helmet, and she felt her resistance fading away. She slumped over in her chair, fully enslaved, and knew that she now served King Sombra, the tyrannical ruler of the Crystal Empire.
Luna's heart ached as she thought of her sister and all that she had lost, but she knew that there was no escaping the grasp of King Sombra's dark magic. She resigned herself to her fate and vowed to serve her new master with all her might.
