Actually, it is more of a prototype version of Fate/Extra and Fate/Apocrypha, back when TM was attempting to make a sequel to Fate/stay night and Fate/hollow ataraxia. Part of it is canon because Most of the material is from Type-Moon, and most of these characters were actually developed for a planned sequel to Fate/stay night and Fate/hollow ataraxia. But I have to admit I wanted to give my own material for it so, I'm writing that too.
