User blog comment:7-45 Fire/How Fairies came to be./@comment-29197449-20170812042549/@comment-29197449-20170812044010

I'd imagine that she may have discovered the existence of the Ethereal Fairies sometime before the series began as she may have been looking for more ways to save Domino from the Ancestral Witches. I wouldn't blame her either as she could've feared that the Company of Light may not be enough to properly fend them off and the combined power of the group's core members (her, Griffin, Saladin, Oritel, Marion and Hagen) could've been enough to allow them to contact the Ethereal Fairies. Unfortunately, that little theory holds no water and relies heavily on whether anyone other than Faragonda (and later the Winx) are aware of the Ethereal Fairies existence.

If the Ethereal Fairies made themselves known to Faragonda before the Winx, it wouldn't make much sense because they exist outside of time. They could've just hopped up in the Winx's pad and revealed themselves to them only before they confronted Diana without the need of showing themselves to Faragonda at all.
