A while back I added this theory to the Phantasy Spelling page, but I took care of that and now I'll put it here. Runescape has both Vampires and Vampyres. Vampires are savage humanoids with disturbingly wide grins, where as Vampyres are much more intelligent and civilized. Not to mention far more powerful. They also have more human faces. Even the Vyrewatch faces are more human than the plain vampires.
