It would be interesting to explore why the Galochios cursed the Aquatos in the first place. Some bad business maybe? Did one family rip the other off? Did two kids from the families fall in love and somehow it ended in heartache? Somehow I picture it as a fight between to old bitter rivals who've been fighting so long they forgotten that the blame is pretty much on both of them, equally instead of on one completely.
The funny thing is, the Galochios are supposed to be psychics, right? So maybe they didn't curse the Aquatos at all. Maybe they only predicted it.
