Forbidden

Inside the castle of the two sisters, one sister is missing. Luna, or formerly Nightmare Moon, was out. Somewhere. That... Celestia had no idea where. It had been two moons since Luna was un-banished from the moon, or rather, came down herself and was forgiven by her sister. Luna had been going out random nights and Celestia let it slide, although she was getting a bit suspicious. Meanwhile, Luna sat in the ruins of the old castle of the two sisters located in the Everfree Forest. Next to her, clearly very, very happy, was King Sombra. He had changed. The evil was gone from him and he was smiling. There seemed to be a glow about him. At least, when he was with Luna. He had his arm around her, not necessarily in a romantic way. Up above, stars seemed to smile at them, the unusual pairing. The moon was not in the sky that night; Luna had decided only the stars would shine on that special night. Sombra had requested it, after all. He gazed at the stars for a moment, then turned to Luna.

"My dearest...it is getting late. You should return to your castle." Luna looked him in the eye.

"Yes, but 'tis only just getting dark. I could lengthen the night for thou..."

Sombra shook his head and smiled. "Oh, Luna, you were always so humourous. I have to go, in the Crystal Empire I have duties to attend to." Luna nodded sadly.

"I will, um...see you tomorrow night? Be prepared for something tomorrow..." he said, a bit awkwardly. He waved, and then in a flash of his new wings was gone. Luna sat there for a moment, staring at the stars and then using her magic arranged them into the shape of Sombra's face. She sighed contentedly and then shivered. She had made that night too cold. Slowly she started to fly back to Canterlot. Behind her, one witness stood. Er, hovered. Rainbow Dash stared at Luna.

"What?" she thought. "Luna is in love?"
