I think we've already established that Lostbelt 6 faeries don't have reproductive glands and just pop up out of thin air when they're "born" and become part of the land when they expire, otherwise they turn into mors

Since Morgan (Tonelico/Vivian) and Castoria are faeries who originated from the planet's inner sea/the Reverse Side of the World, I wonder if they have complete reproductive glands or something
