I wonder how many fairies there are in NL? We know that Tink spent time in FTL, so might well be from FTL, and if so, is she the only fairy in NL? Will pixies who make the pixie dust be a whole other race of beings that are plentiful in NL the way fairies are plentiful in FTL? Or will it be a case that all fairies are “born” in NL, the home of imagination, and some get exported to FTL?
As for the mermaids, I dunno that they’ll necessarily work for PP, but they’re probably happy to help him out if they’re asked, just because they get off on causing chaos and friction, (the one on the JR was loving watching everyone fight).
