Another very interesting take, but I think Dazzlings/Sirens, could be originally from an equivalent of the Sanctuary faction. Not saying you should make it, but I think it would fit quite well, especially that Japanse mermaids are rather scary ...Another bit is, I'm not sure if Star Swirl's and Dazzlings' situation maybe would be interesting, if it was morally gray here, Starswirl here filling up for the Academy faction, who is pretty morally gray.[EDIT]Especially that before Season 4 retconned it with the Scorpan-Star Swirl friendship, Starswirl was said like Sunset, did not understand/knew friendship exacly, althugh one could say Star Swirl and Scorpan saved each other...
