I have the theory of vila* ( fairy)\ human hybrid who was original product of true love, and he isn't made by sex, he was simply born from emotions of his parents. He has unusual silver-blue eyes, as simbol how he was made by first true love, which was invented by his mother, first Blue Fairy and mentor of current one ( blue is colour of fairy-like creatures). His father was unmagican ( totally unable to use magic but there is blessing in curse: he is also invulnerable to almost any type of magic, only magic that has effect on him is true love,not counting because it is partly his invenrion with vila).
VILA*- FAIRY-LIKE CREATURES OF SLAVIC MYTHOLOGY, MORE POWERFUL THAN OTHER BRANCHES OF FAIRY PEOPLE< LIKE WINGED BUT MORE POWERFUL NUMPHS OF GREEK MYTHOLOGY, HUMAN-SIZED, HAVE PASSION FOR WHITE AND BLUE CLOTHES, USUALLY CONTROL WATER BUT CAN ALSO CONTROL OTHER ELEMENTS OF NATURE, FAMOUS FOR BEAUTY AND MAGICAL BLONDE HAIR AND SILVER-BLUE EYES, LIKE FAIRIES IN OTHER MYTHOLOGY, ARE MAGICAL AND DANGEROUS, BEFORE CHRISTIANS CAME THEY WERE GODS, SOMETIMES HAVE RELATIONSHIPS WITH SMART\ BEAUTIFUL OR STRONG PEOPLE ( DEPENDS ON VILA), ALTROUGH THEY MORE PREFER BLONDES, THERE AREN"T MANY OF THEM IN MONTENEGRO, THEIR MAIN COUNTRY, PEOPLE ARE USUALY BLACK -HAIRED , BLACKISH-BROWN EYES AND DARK SKIN, BUT CHILDREN ARE LIKE MOTHERS ( MALES ARE MORE POWERFUL), WHAT IS STRANGE BECAUSE BLACK PIGMENT ARE MORE STRONG THAN BLUE ONES. THEY ARE CURSED, IF THEY FIND THEIR TRUE LOVE, THEIR FAMILIES AND FAMILIES OF THEIR TRUE LOVE WILL BE UNBELIEVABLE UNFORTUNATE, AND THEY AND THEIR LOVERS WILL DIE WITH TERRIBLE, PAINFUL AND DANGEROUS DEATHS.
