So if they continue making a set of miniseries, what other adventures can the remaining crew of Moya have? John and Aeryn are busy raising Baby D'Argo, Chiana's going to Hyneria with Rygel, Jothi's leading his clique in the Luxan Military, the Scarrans and Sebacceans are at peace (barely), Harvey's destroyed, D'argo and Sikozu are presumed dead, Jool's been nuked, Stark is on a Walkabout, Zhaan is still "dead", Crais and Talyn are space dust, and Gramma is living with the last of the Idolans teaching them their innate powers.
Scorpius is hanging around with no purpose. Maldis might still be around. I believe John still has the ability to track wormholes, not create wormhole weaponry. Hyneria's in political upheaval. Then there's the Uncharted Territories and Tormented Space... Rockne and David might have to make a new threat.
