this is True Nightmare, a villain I designed for the MLPFiM universe. He will appear in the pony RPG I'm making and possibly in a DnD campaign I might run. Here's his information: True Nightmare was "born" on the day that Nightmare Moon was created. When an unknown outside force taught Princess Luna to transform into a Nightmare, there was a backlash of magic that activated an ancient nightmare-feeding spirit possessing her helmet. It was this spirit that convinced Luna to revolt against her sister and attempt to create an eternal night, resulting her being banished to the moon. There, the spirit spent 1000 years feeding on Princess Luna's negative energies until it became strong enough to possess her long enough to escape the moon, only to have Luna regain control, attempt the eternal night once again and be defeated by Twilight Sparkle and the Elements of Harmony. After the armor shattered, the princesses and Elements had left and the ruined armor was forgotten, the unknown force returned and repaired the helmet, taking it and hiding it in an unknown location inside Equestria, and casting a powerful spell on it, giving the spirit inside the ability to absorb the negative energies found in the nightmares of everypony in Equestria. After another 1000 years of seclusion, the force once again returned to the helmet and cast one more spell on it, giving it the ability to use the nightmare energy it had collected to manifest a physical body and walk on its own. It was at that moment that True Nightmare first became as he is pictured here. He is the embodiment of Equestria's nightmares. this is my latest drawing. I didn't draw the background but I drew the ponies in it. it's for my new RP tumblr I made with a friend of mine. and yes that's Rune Sigilsign AND his Rule63 equivalent, Arcana Sealmark
