Wait, the tantabus forced merged with you? I-i'm sorry Luna, your appearance really caught me off guard. I mean, you basically had the equivalent of any random pony falling into a tar pit and coming out looking like Sombra, are you alright?
“This is the enchanted body that Tantobus gave me before he was forced to merge with my soul. Before the elements hit me, i had lost a large chunk of my soul, usually by sacrificing pieces of it. Tantibus replaced those pieces with corruption and darkness, keeping me alive.” She sighed and looked up, a stern look on her face. She was clearly conflicted on ger current state of being.
“After the elements hit me, they ourged the darkness and corruption in my soul. I had lost too much of my soul for me to survive very long without it. So, against my pleas, tantibus used himself to repair my soul. Doing so perminantly changed by body into Nightmare Moon, as I was no longer able to survive as just Luna.”
