Zera is quite the interesting existence, is she just an illusion created by a past void within Mavis where her feelings for Zera ended up manifesting itself into an actual existence or is she really Zera’s soul existing? What ever the case, “Zera” exist and now has rejoined with Mavis becoming one once again. Potentially “Zera” may be key in the magic behind Fairy Heart or at the very least help explain what Fairy Heart really is.
