The implication being that A: Communications have been restored between the tribes and B: The Heterodyne Boys got to bring back some goodies from Skifander. Could the Skifandrans be, like the Bana-Mighdall, a 'lost' tribe as a result of the tumult when the Amazons were enslaved and Antiope went her own way, splitting the tribe between herself and her sister-Queen Hippolyte? A proto-Skifandran fragment could have been lost during the wanderings and travails of the Bana-Mighdall, or even come from an untold tale of attrition as the gods led Hippolyte's group to Paradise Island and New Themiscyra.
