My headcanon: Perhaps Merlin created Blue (and the other fairies then) with his faith and belief. At first it was only Blue. She becomed into a legend (Reul Ghorm and the Blue Star) and then people started to believe in fairies and the others (TL, Nova, Tink, FGM, Silvermist) borned too with the time.
