A Vampyre (spelled with a Y) is a real life Human person (sometimes seen as OtherKin or part of Satanism) related to a spiritual state and similar to Magick spelled with a K which is spiritual art and real.
Just as the use of the letter K in magick is used to distinguish imagined from real, the Y in Vampyer is also used to separate imagined and real.
