Doctor keith worked for Axel Labs, a research facility that created mutated vaccines and powerful chemicals that changed the human body, inside and out.. Keith was still quite new to Axel labs, and was assigned a patient to test things on before he got promoted. The patient in question was abducted, like all the others, at an early age and was tested on. they were human, though with the huge grey wings that sprouted from their shoulder blades and their lack of english parted them from society.
