Northstar and Aurora were revealed to be half-elven. This "explained" Aurora's multiple personality disorder as being a side effect of her dual nature, and also Northstars pointy ears, and presumably his proclivity for wanting to have sex with men (Though whether that came from the human or elven halves of his nature was, amusingly, never defined). That storyarc ended, IIRC, with both of them being welcomed to Asgard... or somesuch.
