Gerhardt Mechanica, the High Lord of the Research and Development branch of the Human Kingdom, has been cast out of his universe by Silvanus, a lesser god of nature with a serious grudge against him. However, the Equestria he ends up in is not like the one we all know. Instead it is a land cast in eternal night and ruled over by Nightmare Moon, due in no small part to the future temporal interference of Starlight Glimmer. In this world there is no friendship, Harmony is dead, and peace is non-existent there is only fear, nightmares, and violence.

Sometimes to fight a nightmare, one must become a nightmare themselves.

(This is an alternate version of The Mechanical Technomancer in Equestria: Technology is Magic. It is strongly recommended that you read that first otherwise you may lack some context for this story. At the very least you should read the beginning of the prologue in that version before reading this version.)

(I'm not sure if this counts as a sequel so I'm treating it as if it's its own thing for the moment)
