Science fantasy is a hybrid genre that draws upon and combines tropes and elements from science fiction and fantasy. In conventional science fiction, the world is presented as being scientifically logical. Conventional fantasy stories contain mostly supernatural and artistic elements, disregarding the laws of physics and the constraints of the real world. Science fantasy, then, is presented scientifically logical and supplied with science-like explanations of its supernatural elements. Like science fantasy, a hippogryph is a strange paradox. combining the elegance of a giant eagle with the stability of a horse. It is a hybrid of two things that cannot logically go together. Somehow the unlikely remix produces something that elevates both of its antecedents. Hippogryph Future began as a hybrid of the D20 Future SRD and Fate Accelerated. The horse and the eagle. Not a conversion of one to the other, but a whole, new thing incorporating the strengths of both. I like how it turned out. Hopefully, you will enjoy it for what it is. - from the publisher's blurb
